Cabot Oil & Gas Corporation Reports 294% Reserve Replacement
Feb 18, 1998

HOUSTON, Feb. 18 /PRNewswire/ -- Cabot Oil & Gas Corporation (NYSE: COG) announced today that for the year-end December 31, 1997, the Company replaced 294% of its production through its ongoing drilling and acquisition efforts. From the drill bit alone, Cabot Oil & Gas Corporation successfully replaced 168% of production, adding 114.0 Bcfe, while acquisitions replaced 114%, or 77.4 Bcfe. Positive revisions of 7.3 Bcfe constitute the balance of additions.

Charles P. Siess, Jr., Chairman and Chief Executive Officer stated, "These results continue to verify our ongoing strategy to grow through the drill bit while pursuing synergistic acquisitions. In a time when companies in our industry are struggling to replace reserves, we accomplished this task in a cost efficient manner. Finding costs from drilling, including revisions, totaled $.67 per Mcfe while finding costs from all sources was $.64 per Mcfe." Siess added, "This brings our three-year average finding costs to a very competitive level near $.60 per Mcfe."

After taking into account the 139 Bcfe of reserves that were sold and the 67.7 Bcfe of production during 1997, year-end reserves were 939 Bcfe, less than 1% below the comparable number at December 31, 1996. "We are pleased that we were able to maintain our level of reserves and, at the same time, improve on the overall quality of our asset base," commented Siess. Also, at year-end, discounted future net cash flows (pre-tax PV-10) attributable to proved oil and natural gas reserves totaled $839 million. This is down from last year due to a $1.11 per Mcf reduction in year-end gas prices between periods.
