Gasco Energy Provides Q1-12 Operations Update

DENVER — (PR Newswire) — April 24, 2012 — Gasco Energy, Inc. (NYSE Amex: GSX) today provided an interim operations update on its Riverbend Project in Utah’s Uinta Basin and on its California projects in the San Joaquin Basin.

Riverbend Project Operations Update

Green River Oil Well Completion Operations

As previously announced, during Q1-12 Gasco successfully completed two Green River Formation oil wells, the Federal #34-19 and the Federal #23-30.  The wells are on artificial lift and continue to produce oil as expected.  The Company expects to drill additional Green River oil wells during the second half of 2012.  As previously announced, the wells had seven-day average initial production rates of 67 barrels of oil per day (BOPD) and 50 BOPD, respectively.  After nearly 90 days on production, the wells have averaged approximately 21 and 15 BOPD and both have now stabilized at approximately these same average rates.

Natural Gas Completion Operations

During Q1-12, Gasco recompleted 1.0 gross wells (0.4 net without adjusting for JV interest) natural gas wells to target up-hole pay zones in exiting wellbores.  Gasco currently has an inventory of 14 operated wells with up-hole recompletions and has one Upper Mancos well awaiting initial completion activities.  The Company contracts drilling rigs as needed and does not currently have a rig under contract at this time.  Increased activity in drilling natural gas wells and in recompletions is scheduled to commence during the second half of 2012.  As of April 23, 2012, Gasco operated 135 gross wells.

Quarterly Production

Estimated cumulative net production for the quarter ended March 31, 2012 was 891 million cubic feet equivalent (MMcfe), a 7.1% decrease from Q1-11’s production of 959 MMcfe, and a 0.1% increase in sequential quarterly equivalent production of 884 MMcfe.  During Q1-12, Gasco’s Uinta Basin joint venture partner received its 50% interest in 10 days of production subsequent to the March 22, 2012 closing of the joint venture.  The Company estimates that approximately 36 MMcfe of production was attributed to the joint venture partner’s interest in the 10-day period.  On a comparable basis, sequential quarterly production would have grown by 4.9% and quarter-over-quarter production would have decreased by 3.3%.

By commodity, Gasco posted improved crude oil volumes of 9,885 barrels of oil for Q1-12, as compared to 7,950 barrels in Q4-11, a 24.3% increase sequentially.  The Company attributes the oil production growth to the addition of two new-drill Green River Formation oil wells that began producing during Q1-12.  Natural gas volumes of 832 MMcf for Q1-12 were off only fractionally as compared to the Q4-11 sequential quarter.

California Projects Update

Willow Springs

The Willow Springs operator recently commenced testing the initial well.  Testing is ongoing and further details will be provided once testing operations have been completed to the satisfaction of the operator.

Antelope Valley Trend

The operator of this prospect trend is finalizing 3-D seismic data processing.  They are working the data and have begun to select initial locations.

Management Comment

“We are encouraged that the Willow Springs operator has opted to test the well to determine the potential for economic rates of hydrocarbon production,” said King Grant, Gasco’s President and CEO.  “While it is too early to determine the ultimate success of this well, oil shows and log analysis indicated that further testing should be performed.  The impact of our Green River oil program was evidenced by the 24% growth in sequential quarter oil production  Q1-12 did not reflect the full effect of the sale of reserves and production to our JV partner, but it does demonstrate the potential impact of our Green River oil program on our operations.”
