                       HARVEST NATURAL RESOURCES ANNOUNCES
                           THIRD QUARTER 2004 RESULTS

         HOUSTON, Texas (November 4, 2004) - Harvest Natural Resources, Inc.
(NYSE: HNR) today announced 2004 third quarter earnings of $5.3 million, or
$0.14 per diluted share. These results compare with net income of $46.4 million,
or $1.25 per diluted share, for the same period last year. The 2004 third
quarter results include $1.0 million of charges related to project evaluation of
Russian properties and $2.9 million for the $85 million prepayment of the
Company's 2007 senior notes. Excluding these charges, 2004 third quarter net
income would have been $9.2 million, or $0.24 per diluted share. The 2003 third
quarter results included a $46.3 million gain on the sale of the Company's 34
percent equity interest in LLC Geoilbent, a Russian company operating in West
Siberia. See Reconciliation of GAAP Measures to Non-GAAP Measures in table
below.

         Net income for the nine months ended September 30, 2004 was $19.1
million, or $0.50 per diluted share, compared with net income of $19.5 million,
or $0.53 per diluted share, for the same period last year. The nine months ended
September 30, 2003 included a $46.3 million gain on sale, offset in part by
$30.5 million equity in net loss related to Geoilbent. See Reconciliation of
GAAP Measures to Non-GAAP Measures in table below.

         Discretionary cash flow (defined as cash flows from operating
activities before changes in operating assets and liabilities) was $19.6 million
for the 2004 third quarter compared with $7.6 million for the 2003 third
quarter. Discretionary cash flow for the nine months ended September 30, 2004
was $54.8 million, compared with the $21.9 million for the same period last
year. See Reconciliation of GAAP Measures to Non-GAAP Measures in table below.

         Production for the 2004 third quarter was 1.9 million barrels of oil
and 7.9 billion cubic feet (Bcf) of natural gas for a combined total production
of 3.2 million barrels of oil equivalent. Production for the first nine months
of 2004 was 9.7 million barrels of oil equivalent including 5.7 million barrels
of oil and 23.8 Bcf of gas. Production for the same periods last year, which
consisted of oil only, was 2.0 million for the third quarter and 5.3 million
barrels for the nine months respectively.

         Harvest President and Chief Executive Officer, Dr. Peter J. Hill, said,
"We continue to deliver strong results based on sustained high gas production,
high oil prices and lower operating expenses. We have two rigs drilling oil
wells in our Uracoa Field and expect both rigs to continue drilling through the
rest of the year and into 2005. As of November 4th, the rigs have completed 10
wells and are projected to drill and complete another six wells by year end.
October oil sales exceeded 25,000 barrels of oil per day (Bopd) and we now
expect to exit the year comfortably within our 25,000 and 30,000 Bopd guidance."

         The Company received an average of $19.87 per barrel of oil for 2004
third quarter sales, an increase of $5.90 per barrel over the $13.97 per barrel
average for the same period last year. The average the Company received for the
nine months ended September 30, 2004 was $17.88 per barrel of oil, an increase
of $3.77 per barrel over the $14.11 per barrel average for the same period in
2003. Revenue for the nine months ended September 30, 2004 included 0.5 million
barrels of oil at a $7.00 fixed price. The volume of fixed price oil delivered
to PDVSA is based on the volumes of the Company natural gas sales. The Company
receives $1.03 per thousand cubic feet of natural gas delivered to PDVSA.

         Hill said, "During the third quarter, our 80% owned Venezuelan
subsidiary, Harvest Vinccler, purchased West Texas Intermediate (WTI) puts for
10,000 barrels of oil per day (Bopd) for 2005. The puts have an average floor
price of $42.20 per barrel. Historically, Harvest Vinccler receives
approximately 48% of WTI for most of the oil it delivers to PDVSA. Consequently,
the puts have the effect of hedging almost 21,000 Bopd of our 2005 production.
The floor price set by the puts help protect our 2005 cash flow and give us the
opportunity to both fund our capital expenditure program and maintain our cash
position."

         Operating expenses were $7.9 million, or $2.46 per barrel of oil
equivalent (Boe), for 2004 third quarter compared with $7.7 million, or $3.87
per barrel of oil equivalent, for last year's third quarter. Operating expenses
for the 2004 first nine months were $22.6 million, or $2.34 per Boe, compared
with $23.7 million, or $4.45 per Boe, for the same period in 2003.

         Hill continued, "We prepaid the $85 million of senior notes
outstanding, reducing total debt to $13.4 million and eliminating $8 million of
annual interest expense. Our $68 million cash balance and our cash generating
capacity provide us with the financial flexibility to pursue growth
opportunities. We continue to evaluate properties in Venezuela and Russia to
find opportunities which meet our focused acquisition criteria."
