News Release / For Release at 9:00 AM EST, Wednesday, February 5, 2003 Gasco Riverbend Compression Installation Complete DENVER - (PR Newswire) - February 05, 2003 - Gasco Energy, Inc. (OTCBB: GASE) today announced that a new compressor is operating on its Riverbend Project in Utah's Uinta Basin. The additional compression capacity allows the company to begin producing from wells that were shut-in or flowing through constricted orifices and should meet the Company's projected compression needs for the next 12 months. Production was curtailed last fall due to inadequate pipeline compressor capacity on the system that is owned by another independent operator. The wells placed on line are the Federal 23-29 (Gasco-operated; Gasco 25% working interest [WI] and the Federal 42-29 (Gasco-operated; Gasco approximately 65% WI). After 48 hours, the Federal 42-29 is currently producing 1,336 thousand cubic feet per day (Mcfd) and 240 barrels of water per day (BWD) at 1400 psi flowing casing pressure on a 16/64" choke to the sales line. Seven additional completion intervals remain behind pipe in the 42-29. After 48 hours, the Federal 23-29 is currently producing 806 Mcfd and 10 BWD at 1300 psi flowing tubing pressure on a 14/64" choke in a fully completed wellbore to the sales line. The Federal 23-21 (Gasco-operated; Gasco, 50% minimum WI) has been hooked up to the sales line and production facilities are installed with completion to commence immediately. The Lytham Federal 22-22 (Gasco-operated; Gasco minimum 50% WI) remains shut-in pending hookup to the sales line and completion. "We are pleased with the performance of the two wells in these first days of production," said Mike Decker, Gasco's COO. "The 42-29 is currently producing at higher water volumes as we recover our fracture stimulation fluid from the completions and we expect this to decline as the well cleans up. These production results are further confirmation of our belief that commercial development of our Riverbend project is feasible."
