EXHIBIT 99.1 PRESS RELEASE DATED MARCH 7, 2002 4 GASCO ENERGY NEWS RELEASE FOR IMMEDIATE RELEASE GASCO UPGRADES ACREAGE POSITION IN PROPERTY EXCHANGE WITH EL PASO DENVER - March 7, 2002 (PR Newswire) - Gasco Energy, Inc. (OTC BB: GASE) today announced that it has successfully completed a strategic exchange of certain properties located in Utah's Uinta Basin with El Paso Corporation. In the transaction, Gasco receives approximately 2571 net acres located in its Uinta Basin Riverbend Project in exchange for the contractural right to earn Wasatch rights on approximately 10,850 gross Uinta Basin acres (2,713 net acres). Gasco now substantially increases its working interest, essentially making the deal a one-for-one exchange on a net-acreage basis. The acreage Gasco receives contains four well bores, two of which are producing, and three of which have recompletion opportunities. Mike Decker, Gasco's Executive Vice President and Chief Operating Officer, said, "This strategic asset swap facilitates our continued efforts to consolidate and upgrade our acreage position. The transaction nets Gasco a 100% working interest in the Wasatch, Mesaverde, Mancos and deeper formations, a significant improvement from our original contractural right to earn a 25% working interest in the Wasatch. Additionally, Gasco acquires numerous potential drilling locations (100% WI), complemented by recompletion opportunities that may yield near-term cash flow." The Uinta Basin is known to hold a significant amount of recoverable natural gas resources and has recently seen a substantial increase in drilling and production activity. More than 99 Mesaverde wells have been drilled and completed in and around Gasco's Riverbend holdings in the Uinta Basin during the past two years, with only one dry hole.
