                             NUEVO ENERGY COMPANY
             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   The accompanying unaudited condensed consolidated financial statements have
   been prepared in accordance with the rules and regulations of the Securities
   and Exchange Commission and, therefore, do not include all disclosures
   required by accounting principles generally accepted in the United States.
   However, in the opinion of management, these statements include all
   adjustments, which are of a normal recurring nature, necessary to present
   fairly the financial position at June 30, 2001 and December 31, 2000 and the
   results of operations and changes in cash flows for the periods ended June
   30, 2001 and 2000.  These financial statements should be read in conjunction
   with the financial statements and notes to financial statements in the 2000
   Form 10-K of Nuevo Energy Company (the "Company").

   USE OF ESTIMATES

   In order to prepare these financial statements in conformity with accounting
   principles generally accepted in the United States, management of the Company
   has made a number of estimates and assumptions relating to the reporting of
   assets and liabilities and the disclosure of contingent assets and
   liabilities, as well as reserve information, which affects the depletion
   calculation.  Actual results could differ from those estimates.

   DERIVATIVE FINANCIAL INSTRUMENTS

   In June 1998, the Financial Accounting Standards Board ("FASB") issued
   Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
   Derivative Instruments and Hedging Activities".  This statement, as amended
   by SFAS No. 137 and SFAS No. 138, establishes standards of accounting for and
   disclosures of derivative instruments and hedging activities.  This statement
   requires all derivative instruments to be carried on the balance sheet at
   fair value and was effective for the Company beginning January 1, 2001.

   The Company adopted SFAS No. 133 on January 1, 2001. In accordance with the
   current transition provisions of SFAS 133, the Company recorded a net-of-tax
   cumulative-effect transition adjustment of $(16.0) million (net of related
   tax benefit of $10.8 million) in accumulated other comprehensive income
   (loss) to recognize the fair value of its derivatives designated as cash-flow
   hedging instruments at the date of adoption.

   All of the Company's derivative instruments are recognized on the balance
   sheet at their fair value.  The Company currently uses swaps and options to
   hedge its exposure to material changes in the future price of crude oil.

   At June 30, 2001, the Company had recorded $7.2 million (net of related tax
   benefit of $4.8 million) of cumulative hedging losses in other comprehensive
   loss, of which $6.4 million (based on June 30, 2001 forecasted future prices)
   is expected to be reclassified to earnings within the next 12 months.  The
   amounts ultimately reclassified to earnings will vary due to changes in the
   fair value of the open derivative contracts prior to settlement.

   As a result of hedging transactions, oil and gas revenues were reduced by
   $40.9 million and $51.3 million in the first six months of 2001 and 2000,
   respectively.   The portion of the Company's hedging transactions that was
   ineffective was $3,000 for the first six months of 2001 and was recorded in
   interest and other income.

   For the remainder of 2001, the Company has entered into swap arrangements for
   the third quarter on 20,000 BOPD at an average WTI price of $21.22 per Bbl,
   and for the fourth quarter on 15,500 BOPD at an average WTI price of $22.95
   per Bbl. On a physical volume basis, these hedges cover 39% of the Company's
   remaining estimated 2001 oil production.

                                       7

       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                  (UNAUDITED)


   For 2002, the Company has entered into swap arrangements on 12,500 BOPD for
   the first quarter at an average WTI price of $25.91 per Bbl.  For the
   remainder of 2002, the Company purchased put options with a WTI strike price
   of $22.00 per Bbl, on 19,000 BOPD for the second quarter, and on 14,000 BOPD
   for both the third and fourth quarters. All of these agreements expose the
   Company to counterparty credit risk to the extent that the counterparty is
   unable to meet its settlement commitments to the Company.

   In February 1999, the Company entered into a swap arrangement with a major
   financial institution that effectively converted the interest rate on $16.4
   million notional amount of the 9 1/2 % Senior Subordinated Notes due 2008
   ("Notes") to a variable LIBOR-based rate. In addition, the swap arrangement
   also effectively hedged the price at which the Company could repurchase these
   Notes.  For the six months ended June 30, 2000, the Company recorded an
   unrealized loss of $371,000 related to the change in the fair value of the
   Notes.  This swap arrangement was settled in the third quarter of 2000.

   COMPREHENSIVE INCOME (LOSS)

   Comprehensive income (loss) includes net income (loss) and all changes in
   other comprehensive income (loss) including, among other things, foreign
   currency translation adjustments, unrealized gains and losses on certain
   investments in debt and equity securities and changes in the fair value of
   derivatives designated as cash-flow hedges. Comprehensive income (loss) for
   the first six months of 2001 and 2000 was as follows:



                                                 2001              2000

   RECENT ACCOUNTING PRONOUNCEMENTS

   In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
   Obligations."  The statement requires entities to record the fair value of a
   liability for legal obligations associated with the retirement obligations of
   tangible long-lived assets in the period in which it is incurred.  When the
   liability is initially recorded, the entity increases the carrying amount of
   the related long-lived asset.  Over time, accretion of the liability is
   recognized each period, and the capitalized cost is depreciated over the
   useful life of the related asset.  Upon settlement of the liability, an
   entity either settles the obligation for its recorded amount or incurs a gain
   or loss upon settlement.  The standard is effective for fiscal years
   beginning after June 15, 2002, with earlier application encouraged.  The
   Company is currently evaluating the effect of adopting Statement No. 143 on
   its financial statements and has not determined the timing of adoption.

   INVENTORY VALUATION

   Prior to December 2000, the Company recorded inventory relating to quantities
   of processed fuel oil and natural gas liquids in storage at current market
   pricing.  Also, fuel oil in inventory was stated at period-end market prices
   less transportation costs, and the Company recognized changes in the market
   value of inventory from one period to the next as oil revenues.  In December
   2000, the staff of the Securities and Exchange Commission announced that
   commodity inventories should be carried at lower of cost or market rather
   than at market value.  As a result, the Company changed its inventory
   valuation method to the lower of cost or market in the fourth quarter of
   2000, retroactive to the beginning of the year.  Accordingly, the Company's
   quarterly results for 2000 have been restated to reflect this change in
   accounting.

   RECLASSIFICATIONS

   Certain reclassifications of prior year amounts have been made to conform to
   the current presentation.

2. PROPERTY AND EQUIPMENT

   The Company utilizes the successful efforts method of accounting for its
   investments in oil and gas properties. Under successful efforts, oil and gas
   lease acquisition costs and intangible drilling costs associated with
   exploration efforts that result in the discovery of proved reserves and
   costs associated with development drilling, whether or not successful, are
   capitalized when incurred. When a proved property is sold, ceases to produce
   or is abandoned, a gain or loss is recognized. When an entire interest in an
   unproved property is sold for cash or cash equivalent, gain or loss is
   recognized, taking into consideration any recorded impairment. When a partial
   interest in an unproved property is sold, the amount received is treated as a
   reduction of the cost of the interest retained.

   Unproved leasehold costs are capitalized pending the results of exploration
   efforts.  Significant unproved leasehold costs are reviewed periodically and
   a loss is recognized to the extent, if any, that the cost of the property has
   been impaired. Exploration costs, including geological and geophysical
   expenses, exploratory dry holes and delay rentals, are charged to expense as
   incurred.

   Costs of successful wells, development dry holes and proved leases are
   capitalized and depleted on a unit-of-production basis over the life of the
   remaining proved reserves.  Capitalized drilling costs are depleted on a
   unit-of-production basis over the life of the remaining proved developed
   reserves.  Estimated costs (net of salvage value) of dismantlement,
   abandonment and site remediation are computed by the Company and an
   independent consultant, and are included when calculating depreciation and
   depletion using the unit-of-production method.

   In accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived
   Assets and for Long-Lived Assets to be Disposed of", the Company reviews its
   long-lived assets to be held and used, including proved oil and gas
   properties accounted for using the successful efforts method of accounting,
   on a depletable unit basis whenever events or circumstances indicate that the
   carrying value of those assets may not be recoverable. SFAS No. 121 requires
   an impairment loss be recognized when the carrying amount of an asset exceeds
   the sum of the undiscounted estimated future cash flows.  In this
   circumstance, the Company recognizes an impairment loss equal to the
   difference between the carrying value and the fair value of the asset.  Fair
   value is estimated to be the present value of expected future net cash flows
   from proved reserves, utilizing a risk-adjusted rate of return.

3. INDUSTRY SEGMENT INFORMATION

   As of June 30, 2001, the Company's oil and gas exploration and production
   operations were concentrated primarily in two geographic regions:
   domestically, onshore and offshore California, and internationally, offshore
   the Republic of Congo in West Africa (the "Congo").

5. EARNINGS PER SHARE COMPUTATION

   SFAS No. 128 requires a reconciliation of the numerator (income) and
   denominator (shares) of the basic earnings per share ("EPS") computation to
   the numerator and denominator of the diluted EPS computation. The Company's
   reconciliation is as follows:

   Certain of the Company's stock options that would potentially dilute Basic
   EPS in the future were not included in the computation of Diluted EPS because
   to do so would have been antidilutive for the three and six months ended June
   30, 2000.

6. CONTINGENCIES AND OTHER MATTERS

   On June 15, 2001, the Company experienced a failure of a carbon dioxide
   treatment vessel at the Rincon Offshore Separation Facility ("ROSF") located
   in Ventura County, California.  There were no injuries associated with this
   event and the cause of the failure is under investigation.  Crude oil and
   natural gas produced from three fields offshore California are transported
   onshore by pipeline to the ROSF plant where crude oil and water are separated
   and treated, and carbon dioxide is removed from the natural gas stream.  The
   daily net production associated with these fields is 3,000 barrels of crude
   oil and 2.4 MMcf of gas, representing approximately 6% of Nuevo's daily
   production. As of early July, the crude oil production resumed and efforts
   are underway to bring the natural gas production back online. The cost of
   repair less a $20,000 deductible is expected to be covered by insurance. The
   Company may have exposure to costs that may not be recoverable from
   insurance. Such costs would not be expected to be material to the Company's
   operating results, financial condition or liquidity.

   On September 22, 2000, the Company was named as a defendant in the lawsuit
   Thomas Wachtell et. al. v. Nuevo Energy Company et. al. in the Superior Court
   of Los Angeles County, California. The Company successfully removed this
   lawsuit to the United States District Court for the Central District of
   California. The plaintiffs, who own certain interests in the Point Pedernales
   properties, have asserted numerous causes of action including breach of
   contract, fraud and conspiracy in connection with the plaintiff's allegation
   that: (i) royalties have not been properly paid to them for production from
   the Point Pedernales field, (ii) payments have not been made to them related
   to production from the Sacate field, and, (iii) the Company has failed to
   recognize the plaintiff's interests in the Tranquillon Ridge project. The
   plaintiffs have not specified damages. The Company has not yet been required
   to file an answer, but believes the allegations are without merit and intends
   to vigorously contest these claims. Management does not believe that the
   outcome of this matter will have a material adverse impact on the Company's
   operating results, financial condition or liquidity.

   In September 1997, there was a spill of crude oil into the Santa Barbara
   Channel from a pipeline that connects the Company's Point Pedernales field
   with shore-based processing facilities.  The volume of the spill was
   estimated to be 163 barrels of oil. Repairs were completed by the end of
   1997, and production recommenced in December 1997.  The costs of the clean-up
   and the cost to repair the pipeline either have been or are expected

                                       11

   to be covered by insurance held by the Company, less the Company's
   deductibles of $120,000. Additionally, the Company has exposure to certain
   costs that are expected to be recoverable from insurance, including certain
   fines, penalties, and damages, for which the Company has accrued $0.7 million
   as of June 30, 2001 and December 31, 2000, as a receivable and payable. The
   Company may also have exposure to costs that may not be recoverable from
   insurance. Such costs are not quantifiable at this time, but are not expected
   to be material to the Company's operating results, financial condition or
   liquidity.

   The Company has been named as a defendant in certain other lawsuits
   incidental to its business.  Management does not believe that the outcome of
   such litigation will have a material adverse impact on the Company's
   operating results or financial condition.  However, these actions and claims
   in the aggregate seek substantial damages against the Company and are subject
   to the inherent uncertainties in any litigation.  The Company is defending
   itself vigorously in all such matters.

   The Company's international investments involve risks typically associated
   with investments in emerging markets such as an uncertain political,
   economic, legal and tax environment and expropriation and nationalization of
   assets.  In addition, if a dispute arises in its foreign operations, the
   Company may be subject to the exclusive jurisdiction of foreign courts or may
   not be successful in subjecting foreign persons to the jurisdiction of the
   United States.  The Company attempts to conduct its business and financial
   affairs so as to protect against political and economic risks applicable to
   operations in the various countries where it operates, but there can be no
   assurance that the Company will be successful in so protecting itself.  A
   portion of the Company's investment in the Congo is insured through political
   risk insurance provided by the Overseas Private Investment Corporation
   ("OPIC").  The political risk insurance through OPIC covers up to $25.0
   million relating to expropriation and political violence, which is the
   maximum coverage available through OPIC.  The Company has no deductible for
   this insurance.

   In connection with their respective February 1995 acquisitions of two
   subsidiaries (each a "Congo subsidiary") owning interests in the Yombo field
   offshore Congo, the Company and a wholly-owned subsidiary of CMS NOMECO Oil &
   Gas Co.  ("CMS") agreed with the seller of the subsidiaries not to claim
   certain tax losses ("dual consolidated losses") incurred by such subsidiaries
   prior to the acquisitions. Under the tax law in the Congo, as it existed when
   this acquisition took place, if an entity is acquired in its entirety and
   that entity has certain tax attributes, for example tax loss carryforwards
   from operations in the Republic of Congo, the subsequent owners of that
   entity can continue to utilize those losses without restriction. Pursuant to
   the agreement, the Company and CMS may be liable to the seller for the
   recapture of dual consolidated losses (net operating losses of any domestic
   corporation that are subject to an income tax of a foreign country without
   regard to the source of its income or on a residence basis) utilized by the
   seller in years prior to the acquisitions if certain triggering events occur,
   including (i) a disposition by either the Company or CMS of its respective
   Congo subsidiary, (ii) either Congo subsidiary's sale of its interest in the
   Yombo field, (iii) the acquisition of the Company or CMS by another
   consolidated group or (iv) the failure of the Company or CMS's Congo
   subsidiary to continue as a member of its respective consolidated group.  A
   triggering event will not occur, however, if a subsequent purchaser enters
   into certain agreements specified in the consolidated return regulations
   intended to ensure that such dual consolidated losses will not be claimed.
   The only time limit associated with the occurrence of a triggering event
   relates to the utilization of a dual consolidated loss in a foreign
   jurisdiction.  A dual consolidated loss that is utilized to offset income in
   a foreign jurisdiction is only subject to recapture for 15 years following
   the year in which the dual consolidated loss was incurred for US income tax
   purposes.  The Company and CMS have agreed among themselves that the party
   responsible for the triggering event shall indemnify the other for any
   liability to the seller as a result of such triggering event.  The Company's
   potential direct liability could be as much as $42.5 million if a triggering
   event with respect to the Company occurs. Additionally, the Company believes
   that CMS's liability (for which the Company would be jointly liable with an
   indemnification right against CMS) could be as much as $61.0 million.  The
   Company does not expect a triggering event to occur with respect to it or CMS
   and does not believe the agreement will have a material adverse effect upon
   the Company.

7. ACQUISITIONS

   In July 2001, Nuevo entered into a definitive agreement with Coho Anaguid,
   Inc, Anadarko Tunisia Anaguid Company, and Pioneer Natural Resources Anaguid
   Ltd., to acquire a portion of Coho's interest in the Anaguid Permit, a 1.1
   million-acre permit located onshore southern Tunisia in the Ghadames Basin.
   Nuevo's 10.42% working interest increased to 22.5%, subject to approval by
   the Tunisian government. The Anaguid Permit, operated by Anadarko, is on
   trend with the prolific Hassi Berkine and El Borma fields located to the west
   in Algeria and Tunisia. Under the current work commitment, a well is expected
   to be drilled in the Anaguid Permit during the first quarter of 2002.

   In January 2001, the Company acquired approximately 2,900 acres previously
   held by Naftex ARM, LLC, in Kern County, California. The Company paid
   approximately $28.5 million in connection with this acquisition. The newly
   acquired acreage is southeast of the Company's interest in the Cymric field,
   and has current production of approximately 800 BOE per day, of which more
   than half is natural gas. In addition, the acreage provides significant
   development potential.

8. DIVESTITURES

   As of June 17, 2001, Nuevo relinquished the 1.9 million-acre Accra-Keta
   Permit offshore the Republic of Ghana. The Permit was relinquished prior to
   the commencement of the second phase of the work program. Nuevo was the
   operator of this Permit and held a 50% working interest.  An impairment of
   $0.9 million was recorded during the second quarter of 2001 in connection
   with this relinquishment.

   In May 2000, the Company sold its working interest in the Las Cienegas field
   in California for proceeds of approximately $4.6 million.  The Company
   reclassified these assets to assets held for sale during the third quarter of
   1999, at which time it discontinued depleting and depreciating these assets.
   No impairment charge was recorded upon reclassification to assets held for
   sale.  In connection with this sale, the Company unwound hedges of 2,800 BOPD
   for the period May 2000 through December 2000 and recorded an adjusted net
   gain on sale of approximately $0.9 million.

9. SHARE REPURCHASES

   On February 12, 2001, Nuevo's Board of Directors authorized the open market
   repurchase of an additional 1,000,000 shares of common stock increasing the
   amount authorized since December 1997 of up to 5,616,600 shares of
   outstanding Common Stock at times and at prices deemed appropriate by
   management and consistent with the authorization of the Board. During the
   first quarter of 2001, the Company repurchased 127,800 shares at an average
   purchase price of $16.32 per share, including commissions. There were no
   shares repurchased during the second quarter of 2001.  As of June 30, 2001,
   the Company has repurchased 3,608,900 shares since December 1997, on a
   cumulative basis, at an average purchase price of $16.56 per share, including
   commissions, under the current share repurchase program.

   FORWARD LOOKING STATEMENTS

   This document includes "forward looking statements" within the meaning of
   Section 27A of the Securities Act of 1933, as amended (the "Securities Act"),
   and Section 21E of the Securities Exchange Act of 1934 ("Exchange Act") and
   the Private Securities Litigation Reform Act of 1995.  All statements other

   CAPITAL RESOURCES AND LIQUIDITY

   Since inception, the Company has expanded its operations through a series of
   disciplined, low-cost acquisitions of oil and gas properties and the
   subsequent exploitation and development of these properties.  The Company has
   complemented these efforts with divestitures of non-core assets and an
   opportunistic exploration program, which provides exposure to high-potential
   prospects.  The funding of these activities has historically been provided by
   operating cash flows, bank financing, private and public placements of debt
   and equity securities and property divestitures.  Net cash provided by
   operating activities was $65.1 million and $36.3 million for the six months
   ended June 30, 2001 and 2000, respectively.  The Company invested $104.1
   million (including acquisitions of $28.5 million) and $43.2 million in oil
   and gas properties for the six months ended June 30, 2001 and 2000,
   respectively.

   The current borrowing base on the Company's credit facility is $225.0
   million.  At June 30, 2001, there were no outstanding borrowings under the
   revolving credit agreement.  Accordingly, $225.0 million of committed
   revolving credit capacity was unused and available at June 30, 2001. At June
   30, 2001, the Company had a working capital deficit of $31.7 million.

   On February 12, 2001, Nuevo's Board of Directors authorized the open market
   repurchase of an additional 1,000,000 shares of common stock increasing the
   amount authorized since December 1997 of up to 5,616,600 shares of
   outstanding Common Stock at times and at prices deemed appropriate by
   management and consistent with the authorization of the Board. During the
   first quarter of 2001, the Company repurchased 127,800 shares at an average
   purchase price of $16.32 per share, including commissions. There were no
   shares repurchased during the second quarter of 2001.  As of June 30, 2001,
   the Company had repurchased 3,608,900 shares since December 1997, on a
   cumulative basis, at an average purchase price of $16.56 per share, including
   commissions, under the current share repurchase program.

   The Company believes its cash flow from operations and available financing
   sources are sufficient to meet its obligations as they become due and to
   finance its exploration and development programs.

   The following is a description of significant exploration and development
   activity during the first six months of 2001.

   Exploration Activity

   Domestic

   As part of its strategy to explore for deeper, larger prospects and lighter
   hydrocarbons onshore California, in January 2001 the Company acquired
   approximately 2,900 acres previously held by Naftex ARM, LLC, in Kern County,
   California for approximately $28.5 million. The newly acquired acreage is
   southeast of Nuevo's deep Point of Rocks ("POR") discovery, the Star Fee 701
   well. While there is considerable exploration potential in this acreage, it
   has the additional benefit of current production of approximately 800 BOE per
   day, of which more than half is natural gas. In addition, the acreage
   provides significant development potential.

   The Star Fee 701 well has produced more than 250,000 BOE since mid-August
   2000. The Star Fee 701 well is currently producing approximately 260 BOE per
   day, consisting of  30 API oil and just under 400 thousand cubic feet per day
   of associated gas, from a single sand package within the POR formation. This
   discovery well was drilled to a total depth of 11,200 feet and penetrated
   four POR sand packages.  Total net pay from the upper two sand packages is
   approximately 500 feet. The production capability of the two lower zones is
   currently unknown.

   In June, Nuevo spud its second POR prospect, Cutthroat. The Cutthroat
   exploratory well will be drilled to a total depth of 14,000 feet and is
   designed to test five zones within the POR formation. The Cutthroat prospect
   is located on acreage acquired from Naftex ARM, LLC, in Kern County.  During
   the second quarter, Nuevo acquired almost 100 miles of 2D seismic and
   purchased approximately 23 square miles of 3D seismic data in southern Kern
   County to better delineate the deep Star Fee structure and to help identify
   new opportunities within the POR trend.

   Two shallow Stevens Sand prospects, Moneypenny and Doubleshot, were drilled
   during the second quarter in the Buena Vista Hills area. Both wells were dry
   holes and Nuevo held a 30% working interest in each prospect. Net dry hole
   costs to Nuevo totaled about $375,000 for both wells.

   During the first quarter of 2001, Nuevo drilled a shallow gas discovery, the
   Golden 1-21 well, in Kern County California.  This well was drilled to a
   total depth of 6,050 feet and initially produced at a rate of approximately 1
   MMcfd.  The Golden 1-21 well produced cumulative production of 32 MMcf.
   After an unsuccessful workover, the productive interval was found to be
   depleted, and the well will be plugged and abandoned.

                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


   Six exploration wells will spud in California in July and August. These
   include two Temblor Formation tests, Thunderball and Steelhead, two shallow
   gas wells, Brook and a follow-up to the Golden 1-21, and one Stevens Channel
   test, Goldeneye.

   International

   In July 2001, Nuevo entered into a definitive agreement with Coho Anaguid,
   Inc, Anadarko Tunisia Anaguid Company, and Pioneer Natural Resources Anaguid
   Ltd., to acquire a portion of Coho's interest in the Anaguid Permit, a 1.1
   million-acre permit located onshore southern Tunisia in the Ghadames Basin.
   Nuevo's 10.42% working interest increased to 22.5%, subject to approval by
   the Tunisian government. The Anaguid Permit, operated by Anadarko, is on
   trend with the prolific Hassi Berkine and El Borma fields located to the west
   in Algeria and Tunisia. Under the current work commitment, a well is
   scheduled to be drilled in the Anaguid Permit during the fourth quarter 2001.

   During the past several years Nuevo has built a 2.2 million-acre portfolio of
   assets onshore and offshore Tunisia which includes the Anaguid Permit as well
   as two additional permits. Nuevo has a 100% interest and is operator of the
   171,000-acre Alyane Permit located offshore Tunisia in the Gulf of Gabes.
   Nuevo also has a 42.8% non-operated interest in the 900,000-acre Fejaj Permit
   onshore Tunisia.

   As of June 17, 2001, Nuevo relinquished the 1.9 million-acre Accra-Keta
   Permit offshore the Republic of Ghana. The Permit was relinquished prior to
   the commencement of the second phase of the work program. Nuevo was the
   operator of this Permit and held a 50% working interest.  During January and
   February 2001, Nuevo drilled the NAK #1 exploratory well in the Accra-Keta
   Permit, offshore the Republic of Ghana. This well was located in
   approximately 1,000 feet of water and was drilled to a total depth of 10,100
   feet.  The Company plugged and abandoned the NAK #1 well as a dry hole.
   Costs to drill this well were approximately $12.5 million (approximately $1.5
   million net to Nuevo), and were incurred and expensed in the first quarter of
   2001.

   Development Activity

   Domestic

   Due to recent high gas prices in California, Nuevo has deferred certain
   capital spending associated with its thermal operations, assuming gas prices
   remain at these high levels for the remainder of the year.   The Company is
   currently evaluating its plans after the recent reduction in California gas
   prices.

   Onshore California, the Company's single largest exploitation project in 2001
   is the continuing development of its Star Fee acreage in the Cymric Field.
   In the first six months of 2001, this development included drilling 20
   Diatomite development wells and one follow-up well to the highly successful
   Star Fee 701 well. The Star Fee 702 well is currently being completed and
   results should be reported in the third quarter of 2001.

   International

   During the first quarter of 2001, the Company replaced the pipelines from the
   two platforms in the Yombo field offshore Congo.  The net cost of the
   pipeline replacements was approximately $5.0 million.  In addition, three
   wells were drilled on the B Platform and one well on the A Platform as part
   of a five-well drilling program. These wells have been completed and are
   currently producing at a combined rate of approximately 4,000 BOPD.  The
   remaining well in this program will be completed in July 2001.

   CALIFORNIA NATURAL GAS AND ELECTRICITY MARKETS

   The price of natural gas and the threat of electrical disruptions are factors
   that create volatility in the California oil and gas operations. Because of
   recent developments, Nuevo has made significant changes in its natural gas
   disposition and electricity production in California.  Regarding natural gas,
   Nuevo has a net long position in California - producing more natural gas than
   consumed in thermal crude production. Moreover, as gas shortages occurred in
   California during late 2000 and early 2001, Nuevo diverted gas from its
   cyclic steaming operations to gas sales.  The prices received for these gas
   sales were higher than would have been

                                       16

                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


   received for oil produced from the cyclic operations using the gas sold. In
   the future, Nuevo's sale of its gas production or use of its gas production
   to generate steam for its cyclic operations will depend on market conditions
   in California for oil and natural gas.

   In California, Nuevo can generate a total of 22.5 Megawatts ("MW") of power
   at various sites.  Two turbines came on-line at the Company's Brea Olinda
   field during 2000 and began using gas that was previously flared.  Three
   turbines in Kern County can produce 12 MW of power and cogenerate 10% of
   Nuevo's total steam needs in thermal operations under normal conditions.  By
   self-generating power in Kern County, Nuevo has reduced it exposure to rising
   electricity prices and unexpected power outages. Nuevo's facilities receive
   power under interruptible service contracts.  Considering the fact that
   California is short of electricity and some Nuevo facilities receive
   interruptible service, the Company could experience periodic power
   interruptions.  In addition, the State of California could change existing
   rules or impose new rules or regulations with respect to power that could
   impact the Company's operating costs.

   DERIVATIVE FINANCIAL INSTRUMENTS

   In June 1998, the Financial Accounting Standards Board ("FASB") issued
   Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
   Derivative Instruments and Hedging Activities".  This statement, as amended
   by SFAS No. 137 and SFAS No. 138, establishes standards of accounting for and
   disclosures of derivative instruments and hedging activities.  This statement
   requires all derivative instruments to be carried on the balance sheet at
   fair value and was effective for the Company beginning January 1, 2001.

   The Company adopted SFAS No. 133 on January 1, 2001. In accordance with the
   current transition provisions of SFAS 133, the Company recorded a net-of-tax
   cumulative-effect transition adjustment of $(16.0) million (net of related
   tax benefit of $10.8 million) in accumulated other comprehensive income
   (loss) to recognize the fair value of its derivatives designated as cash-flow
   hedging instruments at the date of adoption.

   All of the Company's derivative instruments are recognized on the balance
   sheet at their fair value.  The Company currently uses swaps and options to
   hedge its exposure to material changes in the future price of crude oil.

   At June 30, 2001, the Company had recorded $7.2 million (net of related tax
   benefit of $4.8 million) of cumulative hedging losses in other comprehensive
   loss, of which $6.4 million (based on June 30, 2001 forecasted future prices)
   is expected to be reclassified to earnings within the next 12 months.  The
   amounts ultimately reclassified to earnings will vary due to changes in the
   fair value of the open derivative contracts prior to settlement.

   As a result of hedging transactions, oil and gas revenues were reduced by
   $40.9 million and $51.3 million in the first six months of 2001 and 2000,
   respectively.   The portion of the Company's hedging transactions that was
   ineffective was $3,000 for the first six months of 2001 and was recorded in
   interest and other income.

   For the remainder of 2001, the Company has entered into swap arrangements for
   the third quarter on 20,000 BOPD at an average WTI price of $21.22 per Bbl,
   and for the fourth quarter on 15,500 BOPD at an average WTI price of $22.95
   per Bbl. On a physical volume basis, these hedges cover 39% of the Company's
   remaining estimated 2001 oil production.

   For 2002, the Company has entered into swap arrangements on 12,500 BOPD for
   the first quarter at an average WTI price of $25.91 per Bbl.  For the
   remainder of 2002, the Company purchased put options with a WTI strike price
   of $22.00 per Bbl, on 19,000 BOPD for the second quarter, and on 14,000 BOPD
   for both the third and fourth quarters. All of these agreements expose the
   Company to counterparty credit risk to the extent that the counterparty is
   unable to meet its settlement commitments to the Company.

   In February 1999, the Company entered into a swap arrangement with a major
   financial institution that effectively converted the interest rate on $16.4
   million notional amount of the 9 1/2 % Senior Subordinated Notes

                                       17

   due 2008 ("Notes") to a variable LIBOR-based rate. In addition, the swap
   arrangement also effectively hedged the price at which the Company could
   repurchase these Notes. For the six months ended June 30, 2000, the Company
   recorded an unrealized loss of $371,000 related to the change in the fair
   value of the Notes. This swap arrangement was settled in the third quarter of
   2000.

   RECENT ACCOUNTING PRONOUNCEMENTS

   In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
   Obligations."  The statement requires entities to record the fair value of a
   liability for legal obligations associated with the retirement obligations of
   tangible long-lived assets in the period in which it is incurred.  When the
   liability is initially recorded, the entity increases the carrying amount of
   the related long-lived asset.  Over time, accretion of the liability is
   recognized each period, and the capitalized cost is depreciated over the
   useful life of the related asset.  Upon settlement of the liability, an
   entity either settles the obligation for its recorded amount or incurs a gain
   or loss upon settlement.  The standard is effective for fiscal years
   beginning after June 15, 2002, with earlier application encouraged.  The
   Company is currently evaluating the effect of adopting Statement No. 143 on
   its financial statements and has not determined the timing of adoption.

Revenues

Oil and Gas Revenues:

Oil and gas revenues for the three months ended June 30, 2001, were $100.3
million, or 45% higher than oil and gas revenues for the same period in 2000.
This increase is primarily due to a 15% increase in realized oil prices and a
234% increase in realized gas prices. Second quarter 2001 oil price realizations
reflect hedging losses of $19.4 million, or $4.60 per barrel compared with
hedging losses of $24.8 million, or $6.03 per barrel in the second quarter of
2000.

Domestic:  Oil and gas revenues for the three months ended June 30, 2001, were
48% higher than oil and gas revenues for the same period in 2000.  This increase
is primarily due to a 17% improvement in average realized oil prices and a 234%
improvement in average realized gas prices, slightly offset by a 2% decrease in
total production. The realized oil price of $15.32 per barrel for the second
quarter of 2001 includes negative hedging results of $5.26 per barrel of oil
compared with a realized oil price of $13.12 per barrel for the second quarter
of 2000, which includes negative hedging results of $6.81 per barrel of oil.

                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


International:  Oil revenues for the three months ended June 30, 2001, increased
18% as compared to the same period in 2000.  This increase relates to the timing
of oil shipments and the recognition of revenue.  Current production is stored
and inventory is recorded on the balance sheet at the lower of cost or market.
Revenue is then recognized at the date of shipment. There were no hedges in
place for the second quarter of 2001 relating to international production.  The
realized oil price for the second quarter of 2000 includes hedging gains of
$1.44 per barrel of oil.

Expenses

Lease Operating Expenses:

Lease operating expenses for the three months ended June 30, 2001, were $49.0
million, or 45% higher than for the three months ended June 30, 2000.  The
majority of this increase is due to a $9.7 million increase in steam costs
related to the Company's thermal oil producing operations.  Lease operating
expenses per BOE were $10.30 in the second quarter of 2001, compared to $7.07 in
the same period in 2000.

Domestic: Lease operating expenses per BOE were $10.95 in the second quarter of
2001, compared to $7.12 in the same period in 2000.  Higher steam costs
contributed to the higher lease operating expenses per BOE quarter over quarter.

International: Lease operating expenses per BOE were $5.06 in the second quarter
of 2001, compared to $6.58 in the same period in 2000. The decrease in lease
operating expenses per BOE is primarily attributable to the timing of oil
shipments and the recognition of associated expenses.  Current production is
stored and inventory is recorded on the balance sheet at the lower of cost or
market.  Expense is then recognized at the date of shipment.

Exploration Costs:

Exploration costs, including geological and geophysical ("G&G") costs, dry hole
costs, delay rentals and expensed project costs, were $5.4 million and $1.5
million for the three months ended June 30, 2001 and 2000, respectively. For the
three months ended June 30, 2001, exploration costs were comprised of $3.0
million in G&G, $0.5 million in dry hole costs, $0.1 million in delay rentals,
$0.9 million in impairment costs associated with the Accra-Keta Prospect, and
$0.9 million of other exploration related activities.  For the three months
ended June 30, 2000, exploration costs were comprised of $0.1 million of dry
hole costs, $0.6 million in G&G, $0.2 million in delay rentals and $0.6 million
of other exploration related activities.

Depreciation, Depletion and Amortization:

Depreciation, depletion and amortization for the three months ended June 30,
2001, reflects a 35% increase from the same period in 2000, due to a higher
depletion rate, which primarily resulted from a decrease in reserve estimates at
year-end 2000 versus year-end 1999.  The decrease in reserve estimates was due
to higher gas prices, which are held flat under the SEC reserve case and
adversely impact the economics of the Company's thermally produced oil fields.

Gain on Sale of Assets, net:

Gain on sale of assets for the three months ended June 30, 2001, was $0.2
million, representing subsequent sales price adjustments relating to the
Company's sale of certain oil and gas properties in 2000.  Gain on sale of
assets for the three months ended June 30, 2000, was $0.4 million, representing
subsequent sales price adjustments relating to the Company's sale of certain oil
and gas properties in 1999.

General and Administrative Expenses:

General and administrative expenses were $9.2 million and $7.5 million in the
three months ended June 30, 2001 and 2000, respectively.  The 23% increase is
due primarily to a $1.6 million severance payment related to the resignation of
the Company's Chairman, President and Chief Executive Officer in May 2001.

Interest Expense:

Interest expense of $10.4 million for the three months ended June 30, 2001,
increased 23% as compared to interest expense in the same period in 2000.  The
increase is primarily attributable to the issuance of 9 3/8% Senior Subordinated
Notes due 2010 in the third quarter of 2000, partially offset by a decrease in
outstanding borrowings on the Company's credit facility.

Other Expense:

The 96% decrease in other expense from the second quarter of 2000 to the second
quarter of 2001 is primarily due to the $2.0 million accrual for a lawsuit
settlement and $0.7 million in costs to evaluate potential business
transactions, which were both included in other expense during the second
quarter of 2000.

Net Income (Loss)

Net income of $2.7 million, $0.16 and $0.14 per common share - basic and
diluted, respectivley, was reported for the three months ended June 30, 2001, as
compared to a net loss of $0.7 million, $(0.04) per common share - basic and
diluted, reported for the same period in 2000.

Revenues

Oil and Gas Revenues:

Oil and gas revenues for the six months ended June 30, 2001, were $217.4
million, or 56% higher than oil and gas revenues for the same period in 2000.
This increase is primarily due to a 13% increase in realized oil prices and a
329% increase in realized gas prices.  These increases were partially offset by
a 19% decrease in international oil production that resulted from two pipeline
replacements in the first quarter of 2001. First half 2001 oil price
realizations reflect hedging losses of $40.9 million, or $4.89 per barrel,
compared to hedging losses of $51.3 million, or $6.16 per barrel in the first
half of 2000.

Domestic:  Oil and gas revenues for the six months ended June 30, 2001, were 68%
higher than oil and gas revenues for the same period in 2000.  This increase is
primarily due to a 329% improvement in average realized gas prices and a 17%
improvement in average realized oil prices.  The realized oil price of $15.39
per barrel for the first half of 2001 includes negative hedging results of $40.9
million, or $5.40 per barrel of oil, compared to hedging losses of $53.4
million, or $7.26 per barrel in the first half of 2000.

                CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


International: Oil revenues for the six months ended June 30, 2001 decreased 24%
as compared to the same period in 2000. This increase relates to the timing of
oil shipments and the recognition of revenue. Current production is stored and
inventory is recorded on the balance sheet at the lower of cost or market.
Revenue is then recognized at the date of shipment. There were no hedges in
place for the second quarter of 2001 relating to international production. The
realized oil price for the first half of 2000 includes hedging gains of $2.08
per barrel of oil.

Gain (loss) on Sale of Assets, net:

Loss on sale of assets for the six months ended June 30, 2001, was $0.1 million,
representing subsequent sales price adjustments relating to the Company's sale
of certain oil and gas properties in 2000.  Gain on sale of assets for the six
months ended June 30, 2000, was $0.5 million, primarily representing a gain on
the sale of certain non-core California properties.

Expenses

Lease Operating Expenses:

Lease operating expenses for the six months ended June 30, 2001, were $106.3
million, or 63% higher than for the six months ended June 30, 2000.  This
increase is primarily due to a $31.1 million increase in steam costs resulting
from higher natural gas prices.  Lease operating expenses per BOE were $11.09 in
the first half of 2001, compared to $6.70 in the same period in 2000.

Domestic: Lease operating expenses per BOE were $11.51 in the first half of
2001, compared to $6.70 in the same period in 2000.  Higher steam costs
accounted for $3.56 of the per BOE increase, period over period.

International:  Lease operating expenses per BOE were $6.43 in the first half of
2001, compared to $6.71 in the same period in 2000.  The increase in lease
operating expenses per BOE is primarily attributable to the timing of oil
shipments and the recognition of associated expenses.  Current production is
stored and inventory is recorded on the balance sheet at the lower of cost or
market.  Expense is then recognized at the date of shipment.

Exploration Costs:

Exploration costs, including G&G costs, dry hole costs, delay rentals and
expensed project costs, were $8.0 million and $4.7 million for the six months
ended June 30, 2001 and 2000, respectively. For the six months ended June 30,
2001, exploration costs were comprised of $2.0 million of dry hole costs (for
the dry hole in Ghana), $4.1 million in G&G, $0.1 million in delay rentals, $0.9
million in impairment costs associated with the Accra-Keta prospect, and $0.9
million of other exploration related activities.  For the six months ended June
30, 2000, exploration costs were comprised of $3.8 million in G&G (primarily for
3-D seismic acquisition and processing in the Accra-Keta prospect offshore
Ghana), $0.1 million in dry hole costs, $0.2 million in delay rentals, and $0.6
million of other exploration related activities.

Depreciation, Depletion and Amortization:

Depreciation, depletion and amortization for the six months ended June 30, 2001,
reflects a 28% increase from the same period in 2000 due to a higher depletion
rate, which primarily resulted from a decrease in reserve estimates at year-end
2000 versus year-end 1999.  The decrease in reserve estimates was due to higher
gas prices, which are held flat under the SEC reserve case and adversely impact
the economics of the Company's thermally produced oil fields

General and Administrative Expenses:

General and administrative expenses were $16.5 million and $16.2 million for the
six months ended June 30, 2001 and 2000, respectively.  The first six months of
2001 includes a positive adjustment to bonus accruals for 2000, which is offset
by a $1.6 million severance payment related to the resignation of the Company's
Chairman, President and Chief Executive Officer in May 2001.

Interest Expense:

Interest expense of $21.6 million for the six months ended June 30, 2001,
increased 28% as compared to interest expense in the same period in 2000. The
increase is primarily attributable to the issuance of 9 3/8% Senior Subordinated
Notes due 2010 in the third quarter of 2000, partially offset by a decrease in
outstanding borrowings on the Company's credit facility.

Other Expense:

The 51% decrease in other expense from the first half of 2000 to the first half
of 2001 is primarily due to a $2.0 million accrual for a lawsuit settlement in
2000 and $0.7 million in costs to evaluate potential business transactions
incurred during the second quarter of 2000.

Net Income (Loss)

Net income of $12.3 million, $0.74 and $0.71 per common share - basic and
diluted, respectively, was reported for the six months ended June 30, 2001, as
compared to net loss of $1.2 million, ($0.07) per common share - basic and

ITEM 1.  LEGAL PROCEEDINGS

     See Note 6 to the Notes to Condensed Consolidated Financial Statements.

     On April 5, 2000, the Company filed a lawsuit against ExxonMobil
     Corporation in the United States District Court for the Central District of
     California, Western Division.  The Company and ExxonMobil each own a 50%
     interest in the Sacate Field, offshore Santa Barbara County, California,
     which can only be accessed from an existing ExxonMobil platform. The
     Company has alleged that by grossly inflating the fee that ExxonMobil
     insists the Company must pay to use an existing ExxonMobil platform and
     production infrastructure, ExxonMobil failed to submit a proposal for the
     development of the Sacate field consistent with the Unit Operating
     Agreement. The Company therefore believes that it has been denied a
     reasonable opportunity to exercise its rights under the Unit Operating
     Agreement. ExxonMobil contends that Nuevo had not consented to the
     operation and therefore cannot receive its share of production from Sacate
     until ExxonMobil has first recovered certain costs and fees.  As a result,
     Nuevo has neither received revenues nor incurred operating expenses related
     to Sacate.  The Company has alleged that ExxonMobil's actions breach the
     Unit Operating Agreement and the covenant of good faith and fair dealing.
     The Company is seeking damages and a declaratory judgment as to the payment
     that must be made to access ExxonMobil's platform and facilities. The
     Company's capitalized costs associated with Sacate are insignificant.

                         GLOSSARY OF OIL AND GAS TERMS

TERMS USED TO DESCRIBE QUANTITIES OF OIL AND NATURAL GAS

  .   Bbl -- One stock tank barrel, or 42 US gallons liquid volume, of crude oil
             or other liquid hydrocarbons.

  .   Bcf -- One billion cubic feet of natural gas.

  .   Bcfe -- One billion cubic feet of natural gas equivalent.

  .   BOE -- One barrel of oil equivalent, converting gas to oil at the ratio of
             6 Mcf of gas to 1 Bbl of oil.

  .   MBbl -- One thousand Bbls.

  .   Mcf -- One thousand cubic feet of natural gas.

  .   MMBbl -- One million Bbls of oil or other liquid hydrocarbons.

  .   MMcf -- One million cubic feet of natural gas.

  .   MBOE -- One thousand BOE.

  .   MMBOE -- One million BOE.


TERMS USED TO CLASSIFY OUR RESERVE QUANTITIES

  .   Proved reserves -- The estimated quantities of crude oil, natural gas and
      natural gas liquids which, upon analysis of geological and engineering
      data, appear with reasonable certainty to be recoverable in the future
      from known oil and natural gas reservoirs under existing economic and
      operating conditions.

  The SEC definition of proved oil and gas reserves, per Article 4-10(a)(2) of
Regulation S-X, is as follows:

    Proved oil and gas reserves. Proved oil and gas reserves are the estimated
  quantities of crude oil, natural gas, and natural gas liquids which geological
  and engineering data demonstrate with reasonable certainty to be recoverable
  in future years from known reservoirs under existing economic and operating
  conditions, i.e., prices and costs as of the date the estimate is made. Prices
  include consideration of changes in existing prices provided only by
  contractual arrangements, but not on escalations based upon future conditions.

    (a) Reservoirs are considered proved if economic producibility is supported
  by either actual production or conclusive formation test. The area of a
  reservoir considered proved includes (A) that portion delineated by drilling
  and defined by gas-oil and/or oil-water contacts, if any; and (B) the
  immediately adjoining portions not yet drilled, but which can be reasonably
  judged as economically productive on the basis of available geological and
  engineering data. In the absence of information on fluid contacts, the lowest
  known structural occurrence of hydrocarbons controls the lower proved limit of
  the reservoir.

    (b) Reserves which can be produced economically through application of
  improved recovery, techniques (such as fluid injection) are included in the
  "proved" classification when successful testing by a pilot project, or the
  operation of an installed program in the reservoir, provides support for the
  engineering analysis on which the project or program was based.

    (c) Estimates of proved reserves do not include the following: (1) oil that
  may become available from known reservoirs but is classified separately as
  "indicated additional reserves"; (2) crude oil, natural gas, and natural gas
  liquids, the recovery of which is subject to reasonable doubt because of
  uncertainty as to geology, reservoir characteristics, or economic factors; (3)
  crude oil, natural gas, and natural gas liquids, that may occur in undrilled
  prospects; and (4) crude oil, natural gas, and natural gas liquids, that may
  be recovered from oil shales, coal,

                                       28


  gilsonite and other such sources.

  . Proved developed reserves -- Proved reserves that can be expected to be
    recovered through existing wells with existing equipment and operating
    methods.

  . Proved undeveloped reserves -- Proved reserves that are expected to be
    recovered from new wells on undrilled acreage, or from existing wells where
    a relatively major expenditure is required.

TERMS USED TO DESCRIBE THE LEGAL OWNERSHIP OF THE COMPANY'S OIL AND GAS
PROPERTIES

  .   Royalty interest -- A real property interest entitling the owner to
      receive a specified portion of the gross proceeds of the sale of oil and
      natural gas production or, if the conveyance creating the interest
      provides, a specific portion of oil and natural gas produced, without any
      deduction for the costs to explore for, develop or produce the oil and
      natural gas. A royalty interest owner has no right to consent to or
      approve the operation and development of the property, while the owners of
      the working interests have the exclusive right to exploit the mineral on
      the land.

  .   Working interest -- A real property interest entitling the owner to
      receive a specified percentage of the proceeds of the sale of oil and
      natural gas production or a percentage of the production, but requiring
      the owner of the working interest to bear the cost to explore for, develop
      and produce such oil and natural gas. A working interest owner who owns a
      portion of the working interest may participate either as operator or by
      voting his percentage interest to approve or disapprove the appointment of
      an operator and drilling and other major activities in connection with the
      development and operation of a property.

TERMS USED TO DESCRIBE SEISMIC OPERATIONS

  .   Seismic data -- Oil and gas companies use seismic data as their principal
      source of information to locate oil and gas deposits, both to aid in
      exploration for new deposits and to manage or enhance production from
      known reservoirs. To gather seismic data, an energy source is used to send
      sound waves into the subsurface strata. These waves are reflected back to
      the surface by underground formations, where they are detected by
      geophones which digitize and record the reflected waves. Computers are
      then used to process the raw data to develop an image of underground
      formations.

  .   2-D seismic data -- 2-D seismic survey data has been the standard
      acquisition technique used to image geologic formations over a broad area.
      2-D seismic data is collected by a single line of energy sources which
      reflect seismic waves to a single line of geophones. When processed, 2-D
      seismic data produces an image of a single vertical plane of sub-surface
      data.

  .   3-D seismic -- 3-D seismic data is collected using a grid of energy
      sources, which are generally spread over several miles. A 3-D survey
      produces a three dimensional image of the subsurface geology by collecting
      seismic data along parallel lines and creating a cube of information that
      can be divided into various planes, thus improving visualization.
      Consequently, 3-D seismic data is a more reliable indicator of potential
      oil and natural gas reservoirs in the area evaluated.
