Cabot Oil & Gas Finalizes Year-End Reserves
Feb 12, 2001

HOUSTON, Feb. 12 /PRNewswire/ -- Cabot Oil & Gas Corporation (NYSE: COG) today announced the final results of its year-end reserve audit. Total proved reserves increased to 1,018.7 Bcfe at December 31, 2000, compared to 978.7 Bcfe in the prior year. For the year, Cabot replaced 165% of production and reported finding and development costs of $.98 per Mcfe. In total, 104.4 Bcfe was added through the drill bit (adjusted for revisions) and 5.8 Bcfe through acquisitions. Also, at year end, discounted future net cash flows (pre-tax PV10) attributable to proved oil and gas reserves grew from $737.8 million in 1999 to $3.5 billion in 2000 based on a Henry Hub price movement from $2.14 per Mcf in 1999 to an unprecedented $9.52 per Mcf for 2000.

"The significant success of our Gulf Coast drilling program was the primary contributor that drove reserves back over the 1 Tcfe level for the third time in our history," said Ray Seegmiller, Chairman and Chief Executive Officer. "While the year-end natural gas price had a definite impact on the present value of proved reserves, Cabot's reserve base did not change appreciably due to the higher prices."

Seegmiller added, "If our reserves had been valued at a $4.00 price, (which is close to the Henry Hub average for 2000) using the same year-end price differentials, total proved reserves would still be above the 1 Tcfe mark at 1,005.4 Bcfe with a resulting pre-tax PV10 of $1.3 billion."

Listed below are reserve-related disclosures that will be part of the 2000 Form 10-K.
