EXHIBIT 99.1 [HARVEST LETTERHEAD] FOR IMMEDIATE RELEASE HARVEST NATURAL RESOURCES ANNOUNCES FOURTH QUARTER AND 2003 RESULTS HOUSTON, TX - (March 4, 2004) - Harvest Natural Resources, Inc. (NYSE:HNR) today announced 2003 fourth quarter earnings of $7.8 million, or $0.21 per diluted share, compared with $10.4 million, or $0.28 per diluted share, for the same period last year. The 2002 fourth quarter included an income tax benefit of $7.8 million. Discretionary cash flow (defined as cash flows from operating activities before changes in operating assets and liabilities) was $14.9 million for the 2003 fourth quarter compared with $19.8 million for the 2002 fourth quarter. See reconciliation to Generally Accepted Accounting Principles (GAAP) in table below. Net income for the year ended December 31, 2003 was $27.3 million, or $0.74 per diluted share compared with $100.4 million, or $2.78 per diluted share, for 2002. Net income for 2003 includes a $46.6 million gain on the sale of LLC Geoilbent offset, in part, by a $28.9 million equity in net losses of affiliated companies which were related primarily to Geoilbent's full cost ceiling test write down. The $100.4 million net income for 2002 included a $144.0 million gain on the Company's sale of its interest in the Arctic Gas Company. Discretionary cash flow was $36.8 million for 2003 compared with $59.3 million for 2002. See reconciliation to GAAP in table below. Harvest President and Chief Executive Officer, Dr. Peter J. Hill, said, "At the start of the year we said 2003 was a period of transition for Harvest, moving from a company totally dependent on oil production to one that seeks transformational value growth. Taken overall, 2003 was a success. We met our guidance despite losing 37 days of production as a result of the national civil work stoppage in Venezuela and the changing landscape in Russia. Gas sales started in November diversifying our revenue and cash flow streams. Including the new gas sales for the full year, production for 2004 is projected to increase between 50 to 75 percent resulting in strong growth of net income and cash flow. We also signed a Memorandum of Understanding with PDVSA to evaluate, prepare a field development plan and negotiate the rights to develop the Temblador and El Salto Fields. During the year, we closely managed our cash reserves to preserve our financial health and provide a platform for future investment in growth." In Venezuela, production for 2003 was 7.3 million barrels of oil and 2.7 billion cubic feet of natural gas for a combined total production of 7.8 million barrels of oil equivalent. The Company began sales of natural gas on November 25, 2003 and by December 2003 sales had stabilized at volumes between 70 to 80 million cubic feet per day. Production for 2002 was 9.7 million barrels of oil. Sales to Petroleos de Venezuela, S.A. ("PDVSA") were disrupted from December 14, 2002 until February 6, 2003 reducing 2002 sales approximately 0.6 million barrels and 2003 sales by an estimated 1.2 million barrels. In 2003, the Company received an average price of $14.07 per barrel of oil including 7.2 million barrels at an average price of $14.13 and 0.1 million barrels at an average price of $7.00 per barrel. The Company received $1.03 per thousand cubic feet of natural gas sold during 2003. The 2002 average sales price for oil was $13.05 per barrel. Hill said, "During the year we elected to sell our interest in Geoilbent to a major Russian oil and gas company at an attractive price. Our 34 percent minority equity interest in Geoilbent did not provide us with the level of control we wanted with respect to operating plans and financial management consistent with our strategy. Our decision to sell Geoilbent released capital for reinvestment in multiple growth opportunities in Venezuela and Russia and for other corporate purposes." Hill continued, "In 2004, we will pursue investment opportunities in both Venezuela and Russia, drive cost improvements and increase production. We are working to improve margins, enhance cash flows and maximize recovery of our remaining reserves in the South Monagas Unit which is generating strong cash flow based on attractive world oil prices, increased production and lower operating costs per barrel of oil equivalent produced. For the next several years, we believe Venezuela and Russia can provide Harvest with good opportunities for additional growth through the acquisition of large oil and gas development or reactivation projects."
