EXHIBIT 99.1 Gasco - ------ Energy For Release at 8:30 AM EST on Thursday, January 11, 2007 GASCO ENERGY PROVIDES OPERATIONS UPDATE SETS QUARTERLY AND ANNUAL PRODUCTION RECORDS EXITS DECEMBER AT 12 MMCFE/D NET DENVER - (PR Newswire) - January 11, 2007 - Gasco Energy, Inc. (AMEX: GSX) today provided an interim operations update on its Riverbend Project in Utah's Uinta Basin and on its Wyoming Projects in the Green River Basin. Record Quarterly and Annual Production Estimated cumulative net production for the quarter ended December 31, 2006 was 1,092 million cubic feet equivalent (MMcfe), an increase of 15% over third quarter 2006 production of 947 MMcfe, and 41% above fourth quarter 2005's production of 776 MMcfe. Estimated cumulative net production for the year-ended December 31, 2006 was 3,803 MMcfe, an increase of 122% over full-year 2005 production of 1,713 MMcfe. Gasco's exit rate at year-end 2006 was approximately 12 MMcfe per day net to the Company's interest. The Riverbend Project constitutes 100% of Gasco's gross and net production. The Company attributes the rise in sequential production volumes to increased well completion activity during the fourth quarter and full-year 2006 which more than off-set normal production declines. - ------------------------------------------------------------------------------------------------------------------------------------ Three-months Three-months Full-year Ended Ended Ended Dec.31* Sept. 30, Dec.31,* Dec. 31, Dec.31,* Dec.31, 2006 2006 % Change 2006 2005 % Change 2006 2005 % Change -------- ---- ------ ----- ---- ------- ---- ---- ------ Natural Gas / MMcf 1,048 913 15% 1,048 750 40% 3,670 1,649 123% Oil / MBbls 7.3 5.7 28% 7.3 4.3 70% 22.1 10.6 108% Natural Gas Equivalents / MMcfe 1,092 947 15% 1,092 776 41% 3,803 1,713 122% - ------------------------------------------------------------------------------------------------------------------------------------ *Includes Q406 and FY06 preliminary production estimates. Company estimates may differ from the actual results to be reported in its forthcoming filing on Form 10-K for the year-ended December 31, 2006. Drilling Activity During the fourth quarter of 2006, Gasco spudded eight gross wells (5.0 net) and reached total depth on nine gross wells (6.2 net). The Company is currently running three drilling rigs on its Riverbend project and expects to take delivery of a fourth rig, a Nabors new-build, during March 2007. Year-to-date in Utah, Gasco has spudded 30 gross wells (18.4 net), and reached total depth on 29 gross wells (18.0 net). Completion Activity During the fourth quarter of 2006, Gasco conducted initial completion operations on 11 wells (7.5 net) and re-entered two wells (1.3 net) to complete behind-pipe pay zones. 1 - ------------------------------------------------------------------ Gasco Energy Operations Summary Period Q406 FY06 Utah Spudded 8 30 Reached TD 9 29 Completed 11 26 Wyoming Spudded 0 2 Reached TD 0 0 Suspended 0 1 WIP 1 1 - -------------------------------- ----------------- --------------- For the full-year 2006, Gasco conductedinitial completion operations on 26 wells (16.5 net) and re-entered 16 wells (8.0 net) to complete behind-pipe pay zones. Gross and net data provided for wells spudded and wells to total depth include three non-operated wells in which Gasco participated in the third quarter of 2006 with a 25% working interest in each well. Two of the wells spudded during the third quarter of 2006 were in Gasco's Wyoming Projects. This is in line with the revised target of 28 to 30 gross wells (15 net) in Utah that Gasco reiterated at the end of the third quarter after reducing its Utah drilling fleet to three rigs from four rigs. One rig was dropped due to poor performance and excessive downtime for maintenance and repairs. At December 31, 2006, Gasco operated 88 gross wells with two additional wells awaiting completion activities. The Company currently has an inventory of 16 wells with up-hole recompletions. Mancos Shale Test - Riverbend Project, Utah Gasco also today announced that it will spud a deep shale-gas well to test the productive potential of the Wasatch, upper and lower Mesaverde and Blackhawk formations, the Mancos Shale, Juana Lopez and Dakota / Morrison sandstones. The Company permitted the Federal 14-31-9-19 (75% WI - GSX operates) to a proposed total depth of 16,650 feet and expects to spud this well before the end of January 2007. The preliminary well cost estimate to drill and complete the well is $7.3 million ($5.5 million net to Gasco). Estimated time to reach total depth is 75 days from spud. The Federal 14-31-9-19 is located in the core Riverbend Blackhawk Spring Canyon marine trend where Gasco has the most geological control and continues to have consistent and favorable results. Gasco's geological and engineering team expects to encounter numerous stacked over-pressure natural gas pay zones throughout the wellbore. Increased activity by industry targeting deeper pay zones is ongoing in the Uinta Basin with encouraging preliminary results. Geological modeling indicates that the Mancos Shale and associated sandstone members are prevalent under much of Gasco's Uinta Basin leasehold where the natural gas resource can be more efficiently recovered using the proven, modern drilling and completion technologies currently benefiting Rockies operators. Riverbend Gas Gathering - Riverbend Project, Utah Gasco recently completed the linking of the Wilkin Ridge and West Desert gathering systems to its existing 50 MMcfd gas processing facility which began operations in June 2006. Now, up to 95% of produced volumes are processed in the plant, ensuring that production will meet pipeline specifications reducing the likelihood of any future curtailments. The Company currently operates nearly 100 miles of gathering system along with the processing facility. Riverbend Environmental Assessment Approved - Riverbend Project, Utah Gasco recently received approval of its Riverbend Environmental Assessment (EA). The approved EA includes 45 proposed wells within the Spring Canyon marine trend of the Blackhawk Formation. The EA should provide for accelerated permitting approvals from the Bureau of Land Management as the environmental and cultural studies of the 45 proposed well sites have already been completed. Daniel Anticline Prospect - Sublette County, Wyoming Gasco and its partner Hunt Petroleum are currently drilling through 14,800 feet on the Cottonwood Ranch 24-21 (25% WI; Gasco operates), which is permitted to test natural gas potential in the Lance, Mesaverde, Ericson, Rock Springs and Hilliard Shale formations to a proposed total depth of 16,500 feet. The Company expects to reach total depth on the well sometime in the first quarter of 2007. 2 Management Comment Mark Erickson, Gasco's CEO and President said: "The strength and viability of the Company are excellent both on financial and operational fronts. We have a strong cash position along with existing cash flows from operations. We enter 2007 with momentum generated by what we expect will have been the best operational quarter in Gasco's history. Substantial contributions and improvements continue to be implemented by our technical and operational staff. Their efforts are helping to lower drilling costs by reducing drilling days, and by lowering completion costs through aggressive bidding of services. "During the quarter: we reached total depth on a Blackhawk well in a Company-record 17 days, and we now average 25 days based on recent wells; reduced fracturing and open hole logging costs on average by $350,000; increased sequential net production by 15%; and grew gas production to an exit rate of 12 MMcfe/d. These significant achievements are exactly what we would have anticipated in the field lifecycle at Riverbend. By consistently lowering per-well investment, we can confidently say we are moving into the development stage of the Riverbend project. The operations team continues to work diligently to further drive costs out of the system, ultimately improving per-well economics in our plays. "Additionally, we are well positioned to continue production growth in 2007 with our large inventory of low-cost up-hole recompletion opportunities. The addition of a new fourth rig along with improving the quality and performance of our existing rig fleet should also contribute to helping grow production." 2006 Results Gasco expects to announce its full-year 2006 results on March 1, 2007. The Company will schedule a conference call to discuss financial and operational results, which will be announced at a later date.
