ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

On September 16, 2003, Harvest Natural Resources, Inc. (the "Company") entered
into an agreement to sell our equity investment consisting of our 34 percent
interest in LLC Geoilbent ("Geoilbent") to a nominee of the YUKOS Oil Company, a
Russian oil and gas company, for cash of $75.0 million, which included $5.5
million as repayment of an inter-company loan and payables owed to us by
Geoilbent. The proceeds of the sale were reduced by approximately $2.0 million
of selling costs (primarily consulting and legal fees). The Company was paid a
$2.0 million earnest money deposit and the balance of $73.0 million was
deposited in a third-party escrow account with closing conditioned upon final
consents from the Russian Ministry for Antimonopoly Policy and Support for
Entrepreneurship and the European Bank for Reconstruction and Development. These
consents have been received and closing occurred on September 25, 2003. The
amount of consideration that the Company received for this sale was determined
by arms'-length negotiations between the Company and the purchaser's
representatives.

ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

(a)  FINANCIAL STATEMENTS OF BUSINESSES ACQUIRED.

     Not applicable.

(b)  UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

     The Unaudited Pro Forma Condensed Consolidated Financial Information
     reflects the disposition of the entire 34 percent investment in Geoilbent
     and repayment of intercompany loan and payables. The Pro Forma adjustments
     reflect a net gain after tax of $31.9 million which is not reflected in the
     unaudited pro forma condensed consolidated statements of operations. The
     estimated taxable gain on the sale will be offset by net operating losses
     for U.S. federal income tax purposes.

     The unaudited pro forma condensed consolidated balance sheet as of June 30,
     2003 assumes the disposition transaction occurred on that date. The
     unaudited pro forma condensed consolidated statements of operations for the
     six months ended June 30, 2003 and the year ended December 31, 2002 assume
     the disposition occurred at the beginning of the earliest period presented.
     The Company believes the assumptions used provide a reasonable basis for
     presenting the significant effects directly attributable to the disposition
     transaction.

     The unaudited pro forma condensed consolidated financial statements do not
     purport to represent what the Company's results of operations would have
     been if such transactions had occurred on such dates. These unaudited pro
     forma condensed consolidated financial statements should be read in
     conjunction with the Company's Consolidated Financial Statements and
     Management's Discussion and Analysis of Financial Condition and Results of
     Operations.

(1)  To record the sales price ($75.0 million) less selling expenses ($2.0
     million) of the entire 34 percent equity interest in Geoilbent, repayment
     of an intercompany note and other receivables, alternative minimum tax
     ($400) offset by a valuation allowance, and state income tax ($20) on the
     gain. No deferred taxes have been provided due to the utilization of net
     operating loss carry forward and the reversal of our valuation allowance.
     The Company accrued as deferred income 34 percent of Geoilbent's actual
     second quarter and estimated third quarter operating results. The Company
     reports Geoilbent's equity income with a one quarter delay.
