Gasco Energy Provides Third Quarter 2010 Operations Update

DENVER — (PR Newswire) — October 12, 2010 — Gasco Energy, Inc. (NYSE Amex: GSX) today provided an interim operations update on its Riverbend Project in Utah’s Uinta Basin and on its California projects in the San Joaquin Basin.

Riverbend Project Third Quarter Operations Update

Completion Operations

Since beginning its up-hole recompletion program in February 2010, Gasco has successfully completed the initial stages on one Upper Mancos well (none in Q310) and recompleted 16 gross wells (6.47 net) with five gross wells (1.67 net) occurring in the third quarter. The Company is experiencing strong results from the program, resulting in improved production.

Gasco continues to employ cost-effective frac stage designs which average $30,000 per stage and contribute to improved per-well economics.

At September 30, 2010, Gasco operated 133 gross wells. Gasco currently has an inventory of 24 operated wells with up-hole recompletions and has one Upper Mancos well awaiting initial completion activities. Gasco does not have a drilling rig under contract at this time.

Quarterly Production

Estimated cumulative net production for the quarter ended September 30, 2010 was 1,106 million cubic feet equivalent (MMcfe), an increase of 5.9% over third quarter 2009 production of 1,044 MMcfe. The year-over-year increase is new production from up-hole zones added during the first nine months of 2010 which more than offset normal production decline expected from existing wells. The 4% decline in sequential quarter production is attributed to seasonal pipeline curtailments in September 2010 and to the lower number of net wells recompleted in third quarter (1.67), as compared to the second quarter (3.0).
