EXHIBIT 99.1 Gasco - ----- Energy For Immediate Release on Wednesday, April 6, 2005 GASCO ENERGY PROVIDES PRODUCTION AND OPERATIONS UPDATE SEQUENTIAL MONTHLY NET PRODUCTION RISES 25% DENVER - (PR Newswire) - April 6, 2005 - Gasco Energy, Inc. (AMEX: GSX) today provided an interim production and operations update on its Riverbend Project in Utah's Uinta Basin. Quarterly and Monthly Production Estimated cumulative net production for the quarter ended March 31, 2005 was 142.1 million cubic feet equivalent (MMcfe), a sequential increase of 7.6% over the fourth quarter of 2004 (132.1 MMcfe) and 4.5% above first quarter 2004's production of 135.9 MMcfe. Estimated cumulative monthly net production for March 2005 was 54.0 MMcfe, or 210 MMcfe gross. This is a 25% increase from February net production of 43.3 MMcfe and a 27% increase from February gross production of 166.0 MMcfe. Production increases are attributed to completion of new wells during the month partially offset by normal production declines in existing wells. Drilling Activity During the first quarter Gasco spudded five gross wells (2.9 net) and reached total depth on five gross wells (2.9 net). During March, Gasco reached total depth on two wells, the Lamb Trust 24-14 (30% WI) and the Gate Canyon 41-20 (100% WI). In addition, two wells were spudded in March, the Gate Canyon 41-20 (100% WI) and the Lamb Trust 24-22 (30% WI). Completion Activity Gasco conducted initial completion operations on five wells during 2005's first quarter and re-entered four wells to complete pay zones that were behind pipe. March 2005 activity accounted for two of the initial completions and three of the re-entries. Exiting March, Gasco had 24 gross wells on production, a 118% increase from the same date last year, with two more gross wells awaiting completion. The Company currently has three drilling rigs operating in its Uinta Basin Riverbend project area. Management expects 2005 drilling and completion activity in the Company's key operating areas will be greater than the prior year's mark.
