Exhibit 99.1 For Release at 4:30 PM EDT on Tuesday, May 6, 2008 Gasco Energy Announces First Quarter 2008 Financial and Operational Results - Record Cash Flow From Operations - Record Oil & Gas Sales - Mancos Shale Operations Update Provided DENVER, May 6 /PRNewswire-FirstCall/ -- Gasco Energy (Amex: GSX - News) today reported its financial and operating results for the quarter ended March 31, 2008. Financial Results For the first quarter 2008, Gasco reported a net loss attributable to common shareholders of $4.4 million, or $0.04 per share, as compared to $0.2 million, or breakeven results of $0.00 per share, for the same period in 2007. All per-share figures are basic and diluted. Included in the first quarter 2008 results are derivative losses of $6.4 million attributed to hedge effect which is discussed below. Excluding the effect of unrealized derivative losses, a non-GAAP measure, Gasco would have posted net income of $1.5 million or $0.01 per share. The Company did not hedge its volumes in the comparable period in 2007. The Company reported record oil and gas sales for the first quarter 2008 of $8.5 million as compared to $5.9 million for the same period in 2007. The increase in oil and gas sales during the first quarter 2008 is attributed to higher prices received for sales of the Company's natural gas and oil volumes and to greater oil and gas sales volumes during the quarter. Gathering revenues from Gasco's midstream assets were also a Company-record $0.9 million for the first quarter 2008 as compared to $0.5 million in the prior-year period. Greater throughput of third-party natural gas volumes contributed to the rise in gathering revenue. Total revenues for the first quarter were $3.4 million, as compared to $6.4 million in the first quarter 2007. The decrease in total revenues is attributed to the derivative loss. Gasco's average realized gas price was $7.19 per thousand cubic feet of natural gas (Mcf) for the first quarter of 2008, including the effect of hedges, compared to $5.47 per Mcf for the first quarter of 2007. The Company's risk management activities decreased its average gas price by $0.42 per Mcf during the first quarter of 2008. Prior to the impact of hedges, the Company's average price received for its natural gas production during the first quarter of 2008 was approximately $7.61 per Mcf as compared to $5.47 in the prior-year period. The Company did not hedge its volumes in the comparable period in 2007. The average realized oil price was $75.28 per barrel for the first quarter of 2008, up from $45.38 per barrel for the first quarter of 2007. Gasco does not hedge its crude oil volumes. 1 Unit Cost Comparisons - LOE / DD&A / G&A Lease operating expense (LOE) for the first quarter increased to $1.3 million from $0.6 million in the same period in 2007. On a per-unit basis, LOE was at $1.17 per thousand cubic feet of natural gas equivalent (Mcfe) in the first quarter 2008, as compared to $0.57 per Mcfe in the year-ago period. The increase in LOE quarter-over-quarter is attributed to increased operating expenses and production taxes primarily due to the increase in natural gas prices as well as an increase in the number of producing wells. Additionally, Gasco engineers are using a more active wellbore treatment program to inhibit scale build-up and improve rates, which contributed to LOE. With unprecedented crude oil prices, Gasco recently embarked on a Green River oil producer workover program to help improve production from this inventory of wells which it acquired from Dominion in 2006. By comparison, LOE unit costs were down by $0.19 per Mcfe in the first quarter of 2008, as compared to the fourth quarter of 2007. Depletion, depreciation and amortization (DD&A) was $2.4 million for the first quarter 2008, as compared to $2.3 million for the same period in 2007. On a per-unit basis, DD&A for the first quarter 2008 was $2.25 per Mcfe, as compared to $2.22 in the 2007 period. The Company reported general and administrative expense (G&A) of $2.2 million in the first quarter 2008 versus $2.3 million in the same period in 2007. On a per-unit basis, total G&A for first quarter 2008 was $2.02 per Mcfe, as compared to $2.21 per Mcfe for the same period in 2007. G&A expense for the first quarter 2008 includes $0.7 million of non-cash, stock-based compensation expense, or, on a per-unit basis, $0.67 per Mcfe, as compared to the prior-period total of $1.0 million, or $0.91 per Mcfe. Gathering operations expense increased to $0.7 million from $0.4 million in the first quarter 2007. Gasco's total assets at March 31, 2008 were $125.6 million, as compared to $122.5 million at year-end 2007. Net cash provided by operating activities for the first quarter 2008 was a Company-record $5.9 million, as compared to $1.7 million in the same period in 2007. Cash and investments were $2.4 million at March 31, 2008. Also at March 31, 2008, the Company had $12 million drawn on its $250 million reserve-based revolving line of credit with JPMorgan, of which $45 million is currently available for borrowing. Quarterly Production Cumulative net production for the quarter ended March 31, 2008 was 1,085 MMcfe, an increase of 3% from the prior-year net production of 1,051 MMcfe. Operations Update & Subsequent Events Mancos Update In its Mancos program, Gasco has one Full Mancos producer and has drilled 10 wells to the Upper Mancos. Of these 10 wells, four are currently producing, two are flowing back frac fluid, and four are awaiting completion. Gasco is currently drilling an additional Upper Mancos well and a Mancos/Dakota deep test. 2 - ---------------------------------------------------------------------------------------------------------------------------- Gasco Energy Mancos Shale Well Data - ---------------------------------------------------------------------------------------------------------------------------- Initiated 24-hour Initial Well Completion Flow Rate Comment - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Full Mancos; added BH and Mv on 2/11/08, Federal 14-31 6/25/07 1.132 MMcf commingled production - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Federal 21-19 10/23/07 1.764 MMcf Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Federal 32-20 10/23/07 0.200 MMcf Only 300' of Upper Mancos drilled - -------------------------------- ----------------------- ---------------- -------------------------------------------------- State 21-32b 3/25/08 0.934 MMcf Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- SW Federal 12-25 4/7/08 1.495 MMcf Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- State 21-32a 4/15/08 Cleaning up Upper Mancos / BH commingled - -------------------------------- ----------------------- ---------------- -------------------------------------------------- SW Federal 32-25 4/22/08 Cleaning up Upper Mancos / Spring Canyon commingled - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Federal 34-30 Awaiting completion -- Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Lamb Trust 12-23 Awaiting completion -- Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- SW Federal 23-26 Awaiting completion -- Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Federal 14-19 Awaiting completion -- Recently reached TD in Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Federal 32-19 Drilling -- Drilling ahead to Upper Mancos - -------------------------------- ----------------------- ---------------- -------------------------------------------------- GC State 23-16 Drilling -- Rig on down time; Mancos / Dakota test - -------------------------------- ----------------------- ---------------- -------------------------------------------------- Riverbend Area The Company is currently drilling below 9,500 feet in the Federal 32-19 (GSX-operated - 33.33% WI) and recently reached total depth of 14,960 feet on the Federal 14-19 (GSX-operated - 33.33% WI). Gate Canyon Area The Gate Canyon State 23-16 (GSX-operated - 25% WI), a Mancos/Dakota deep test, is currently 2,000 feet below the top of the Mancos Formation, at a depth of approximately 13,550 feet. The drilling rig is on "down time" while the drilling contractor addresses mechanical issues with the rig. Gasco is not responsible for the day-rate charges until the mechanical issues are resolved. Gasco has not received an estimated time at which drilling will recommence. The well was drilled with numerous gas shows and associated flares in the target intervals. The well's proposed total depth is 16,500 feet. Gasco originally estimated that the well would reach total depth in early May, which it believes would have achieved were it not for the rig problems. Other The Company is currently documenting a commitment for a financial partner to take 25% of Gasco's working interest in a 10-well Mancos shale drilling program. Gasco continues to work with its partner NFR Energy to take up to 41.7% of Gasco's working interest in the program. The Riverbend Environmental Impact Statement (EIS) is progressing. The Draft EIS is anticipated to be available for public comment in the coming months and is a top priority for Gasco. 3 Gasco is currently in the process of completing an update of its 3P and Resource report. It expects the results to be available during the second quarter of 2008. Netherland Sewell & Associates, Inc. Gasco's independent reserve engineering firm, is preparing the evaluation. Management Comment Commenting on the first quarter operations and results, Gasco President and CEO Mark Erickson said: "The first quarter was a great start for the year. We demonstrated record cash flow from operations. We are currently producing at record daily rates averaging 31.4 MMcf gross and 14.4 MMcf net production during April 2008. Rockies producers continue to enjoy robust commodity prices for this time of year. "We are encouraged with the results from our Mancos completion program which have demonstrated high initial flow rates with strong flowing pressures. We have made important technological advances with our Mancos completion designs, although there is still much to learn on how to best stimulate the over-pressured interval. Early data, including mud log shows and flares from the Gate Canyon well, indicates potential in each of our historical producing uphole intervals in addition to the Mancos. We are looking forward to evaluating the deeper potential pay zones including the Dakota, which has proven successful for other Uinta operators. "We are more firmly committed to the long-term potential of our large acreage position in the Uinta Basin. We are focused during the remainder of 2008 and beyond to best position the Company to define and capture its leasehold value as highlighted by recent Uinta Basin M&A activity."
