1 Exhibit 99.1 NEWS RELEASE CONTACT: KEVIN R. WHITE OR SHAWN ABERNATHY 405 749-1300 FOR IMMEDIATE RELEASE Tuesday, February 3, 1998 LOUIS DREYFUS NATURAL GAS ANNOUNCES 1997 RESULTS AND YEAR-END RESERVES RECORD REVENUES, CASH FLOWS AND PRODUCTION; NET LOSS FROM ACQUISITION IMPAIRMENT CHARGE Oklahoma City, Oklahoma -- Louis Dreyfus Natural Gas Corp. (NYSE: LD) today announced its financial results for the year ended December 31, 1997. Excluding the effects of a fourth-quarter impairment charge, the Company reported net income of $31.1 million, or $1.03 per share, on total revenue of $232.9 million for 1997. This compares with net income of $21.1 million, or $.76 per share, on total revenue of $189.5 million for 1996. The Company reported record cash flows from operating activities (before working capital changes) for the year ended December 31, 1997 of $127.1 million, which compares to $101.0 million for 1996, an increase of 26%. The 1997 increase in revenues and operating cash flows was achieved primarily through growth in oil and gas production and higher oil and gas prices. The Company reported a net loss of $16.1 million, or $.53 per share, after the effects of a $75.2 million non-cash impairment charge ($47.1 million after tax), substantially all of which was recognized as anticipated in connection with the October 1997 acquisition of American Exploration Company. RECORD PRODUCTION LEVELS Oil and gas production for the year ended December 31, 1997 was 12% higher in relation to the prior year. In total, the Company produced 84.3 Bcfe in 1997 compared to 75.0 Bcfe in 1996. Natural gas production increased to 71.7 Bcf, up 12% compared to 63.9 Bcf produced in 1996. Oil production for 1997 increased 13% to 2.1 MMBbls compared to 1.8 MMBbls for 1996. These 1997 production increases are largely attributable to the October 1997 acquisition of American Exploration Company and the results of the Company's exploration and development drilling program. The Company received an average gas price of $2.52 per Mcf for its 1997 gas production, an 8% increase compared to $2.34 per Mcf for 1996. The average oil price received for 1997 was $19.86 per Bbl compared to $19.56 per 2 Bbl for 1996, an increase of 2%. The prices for both years include the results of the Company's hedging activities. FOURTH QUARTER 1997 RESULTS Excluding the non-cash impairment charge, the Company reported net income of $8.4 million, or $.23 per share, on total revenue of $80.1 million for the quarter ended December 31, 1997. This compares to net income of $7.8 million, or $.28 per share, on total revenue of $54.9 million for the fourth quarter of 1996. Cash flows from operating activities (before changes in working capital) for the fourth quarter of 1997 were sharply higher, increasing 43% to $46.8 million compared to $32.6 million for the fourth quarter of 1996. This improvement was primarily attributable to higher oil and gas production as a result of the American acquisition. The Company reported a net loss of $38.7 million, or $1.03 per share, after the effects of the acquisition impairment charge. 1997 DRILLING PROGRAM The Company expanded its exploration and development activities in each of its core operating areas during 1997. For the year, the Company successfully completed 311 productive wells out of 343 total wells drilled (or 91%), including 233 wells drilled in the state of Texas and 80 wells in Oklahoma. This well count includes 48 exploratory wells, 36 (or 75%) of which were successfully completed as producers. The Company's 1997 drilling activities resulted in the addition of 125 Bcfe of new reserves, replacing 148% of production. 1997 YEAR-END RESERVES The Company added 213 Bcfe to proved oil and gas reserves during 1997, a 22% increase over 1996's year-end proved reserve position of 990 Bcfe. The Company's proved reserves at December 31, 1997 are comprised of 29.1 MMBbls of oil and 1.0 Tcf of natural gas, or 1.2 Tcfe. The present value of the estimated future net revenues from proved reserves discounted at 10% was $1.1 billion. In addition to the reserve growth resulting from the Company's 1997 drilling program, the Company acquired 198 Bcfe (net of sales) during 1997. MANAGEMENT COMMENT Mark Monroe, President and Chief Executive Officer, stated, "1997 was a year of significant achievement for Louis Dreyfus Natural Gas. Through our drilling and acquisition efforts, the Company added reserves equal to more than 350% of production. Compared to last year, we are a substantially larger, stronger company, with total assets now exceeding $1.2 billion. Our 1997 drilling program established records in terms of number of wells drilled and reserves added. We ended the year with an exciting exploration position which has the potential to make a significant impact on our future results. Our growth prospects for 1998 look very bright. Production averaged 320 MMcfe per day for December, a 20 MMcfe per day increase over pro forma combined results for the first half of 1997. We will continue to focus on the 3 strategy that has served us well -- large-scale, risk-balanced drilling in our core operating areas and opportunistic acquisitions." - ----------------------------------- This press release includes certain statements that may be deemed to be "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.
