ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On November 4, 2004, Harvest Natural Resources, Inc. ("Harvest") issued a Press
Release (the "Press Release") providing results for the third quarter ended
September 30, 2004. The Press Release contains information regarding Harvest's
discretionary cash flow, a non-GAAP financial measure which Harvest's management
believes provides useful information to investors regarding the net cash
provided by operating activities without regard to the changes in the operating
assets and liabilities. These changes are short-term in nature and can fluctuate
based on the activities within a single reporting period. The Press Release
includes a reconciliation of the differences between discretionary cash flow and
net cash provided by operating activities.

The foregoing is qualified by reference to the Press Release which is furnished
as an exhibit to this report and incorporated herein by reference.
