1 PETSEC ENERGY LTD (A.C.N. 000 602 700) May 6, 1999 PETSEC ENERGY REPORTS MARCH 1999 QUARTER RESULTS Sydney, Australia - Petsec Energy Ltd (ASX: PSA and NYSE: PSJ), today announced its results for the three months ended March 31, 1999. Under Australian accounting standards, the Company reported an after tax loss of A$9.1 million in the quarter ended March 31, 1999 (1998: a net loss of A$14.3 million). Under U.S. generally accepted accounting principles the Company reported a net loss of US$5.8 million, or US$0.27 per American Depositary Receipt ("ADR"). This is compared to a net loss in the 1998 quarter of US$8.9 million, or US$0.41 per ADR. Net sales in the March quarter were US$9.3 million, down from US$28.0 million in 1998. Net production of 4.1 Bcfe for the quarter was down 65% on the March 1998 quarter production of 11.7 Bcfe. The lower production and reduced net sales follows the sale, effective January 1, 1999 of a 50% working interest in 17 production leases and 6 exploration leases, coupled with natural decline over the twelve month period. On February 1, 1999, Petsec completed the sale to Apache Corporation for US$68.3 million. Proceeds were used to repay bank debt. Cash flow from operating activities in the March quarter was US$8.9 million or US$0.42 per ADR. In 1998 cash flow from operating activities totaled US$23.3 million or US$1.08 per ADR. The Company was the high bidder for two leases at the OCS Central Gulf of Mexico Lease Sale in March 1999. A sole bid of US$1.7 million on Vermilion 258 was successful, and a joint bid with Coastal Corporation for West Delta 113 was also successful with Petsec's share being US$0.3 million. The leases are expected to be awarded within the next two months. No wells were drilled in the first quarter. The Company expects to commence its 1999 drilling program in the June quarter. A total of 6 to 8 wells are anticipated to be drilled during the remainder of 1999, exposing the Company to an unrisked 60 Bcfe in net reserve potential. It is anticipated that most of the wells will be in joint venture with Gulf of Mexico industry partners in order to spread risk and operate within the constraints of operating cash flow. Petsec Energy is an independent oil and gas exploration and production company with its operations in the offshore Gulf of Mexico (based in Lafayette, Louisiana) and its head office in Sydney, Australia.
