1 EXHIBIT 99.3 TUESDAY, FEBRUARY 10, 1998 CONTACT: JEANNE BUCHANAN (713) 653-5095 UMC INCREASES RESERVES 36 PERCENT, REPLACES 366 PERCENT OF PRODUCTION Houston, TX -- United Meridian Corporation today announced that proved energy reserves at year-end 1997 reached a record 162 million barrels of oil equivalent (MMBOE), 36% greater than the 120 MMBOE reported at year-end 1996. After record production volumes of 55 billion cubic feet (BCF) of gas and 8 million barrels of oil, gas reserves totaled 560 BCF and crude oil reserves totaled 69 million barrels compared to year-end 1996 totals of 451 BCF and 45 million barrels. Proved oil reserves accounted for 42 percent of UMC's total proved reserves compared to 37 percent at year-end 1996, a significant step toward achieving the company's goal of more balanced production and reserves. During 1997, the company replaced 366 percent of total production with additions to proved reserves, marking the eighth straight year the company has more than replaced its oil and gas production. UMC achieved this at an all-sources finding cost of $5.47 per barrel of oil equivalent (including additions, revisions of prior reserve estimates, and acquisitions). UMC's North American activities accounted for 58 percent of the company's total reserves and West Africa contributed the balance. On the continued success of the company's drilling program on Block B in Equatorial Guinea, UMC doubled proved oil reserves in the country, booking 40 million barrels (net). "Proved reserves are at the highest level in the company's history, driven by our most active annual drilling program to date," said chairman and chief executive officer John B. Brock. "We drilled 337 wells in 1997 and had an 84% success rate compared to 169 wells drilled in 1996 and a success rate of 80%. We expect 1998 to be another record-breaking year as we complete the merger with Ocean Energy and drill many of the high-impact prospects in our respective exploration inventories." United Meridian Corporation is a Houston-based independent energy company engaged in the exploration, exploitation and acquisition of natural gas and crude oil properties in the United States and Canada. Internationally, the company has exploration and development activities in West Africa's Cote d'Ivoire and Equatorial Guinea, and was recently awarded a block offshore Angola. UMC also has exploration programs underway in Pakistan and Bangladesh.
