EXHIBIT 99.1 PRESS RELEASE DATED FEBRUARY 4, 2002 GASCO ENERGY News Release For Immediate Release GASCO ANNOUNCES STRATEGIC RELATIONSHIP WITH HALLIBURTON 10-WELL UINTA BASIN DRILLING PROGRAM BEGINS IN FEBRUARY DENVER - February 4, 2002 (PR Newswire) - Gasco Energy, Inc. (OTC BB: GASE) announced the signing of a strategic relationship with Halliburton Energy Services, a business segment of Halliburton Company (NYSE: HAL). The agreement encompasses a 10-well pilot program over a period of three years, whichever occurs first, and is part of Gasco's Riverbend Project in the Uinta Basin of northeast Utah. Upon completion of the initial 10 wells, Halliburton has the option to extend the agreement on the same basis for an additional 10 wells during the contract period. The agreement with Halliburton represents a portion of Gasco's drilling activities on its Uinta Basin properties. Mark Erickson, Gasco President and CEO, said, "This is great news. Halliburton's Integrated Solutions Group will team with Gasco engineers on field development planning and solutions integration. A joint technical team brings together Halliburton's best-of-class completion experience and Gasco's substantial exploitation expertise. The structure of this agreement ensures that Halliburton and Gasco are equally motivated to achieve maximum success on each of the wells. The first development well under this agreement, the Federal 23-29 #1, is expected to begin drilling in early February." 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 98 Mesaverde wells have been drilled and completed in the Uinta Basin during the past two years, with only one dry hole.
