Gasco Energy Provides Riverbend Activity Update

DENVER, April 13 /PRNewswire-FirstCall/ -- Gasco Energy, Inc. (OTC Bulletin Board: GASE -News ) today provided an interim operational update on oil and gas activities on its Riverbend Project in Utah's Uinta Basin.

As of the end of the first quarter of 2004, Gasco had gross daily oil and natural gas production of 3.2 million cubic feet equivalent (MMcfe) and net daily oil and natural gas production of 1.9 MMcfe, surface constrained. Production volumes are the highest in company history. Gasco estimates that an additional 0.3 MMcfe of production per day (0.2 MMcfe per day, net) is shut-in due to temporary operational constraints on an interstate pipeline that are expected to be resolved in the next 30 days.

Gate Canyon State 31-21-11-15
During the first quarter of 2004, the Gate Canyon State 31-21-11-15 well was drilled to total depth of 11,430 feet and is awaiting completion design, implementation and pipeline hookup. The well was drilled to test natural gas potential of the Wasatch, Mesaverde and Blackhawk formations. Gasco is continuing to evaluate the well, and the completion activities are initially scheduled to commence during the second quarter of 2004. The gathering line is expected to be completed during April 2004. This well is part of the first 10-well bundle contemplated by agreements with service providers entered into in January 2004.

Wilkin Ridge 12-32-10-17
The Wilkin Ridge 12-32-10-17, which spud on March 16, 2004, has been drilled through 10,775 feet and is expected to reach total depth of 13,100 feet during the month of April 2004. This well is being drilled to test the Wasatch, Mesaverde and Blackhawk formations. This well is also part of the first 10-well bundle under the service parties' agreement.

Second Quarter 2004 Activity
Gasco plans to spud two new wells during the second quarter of 2004 using the current rig. The Company is leasing a second rig that it expects to begin drilling during April 2004. This rig is expected to spud a total of two wells by the end of the second quarter of 2004, making a total of four Gasco- operated wells to be spud this quarter.

Recompletion/Workover Activity
Gasco anticipates leasing a workover rig during the second quarter of 2004 to begin adding additional behind-pipe production from two producing wells located in the Uinta Basin. Gasco is the operator of these wells and acquired interests in them during the first quarter of 2004. The workover rig will also be used in the completion of the wells that are being drilled.

Management Comment
"We are pleased to step up activity on our acreage," said Gasco CEO and president, Mark Erickson. "We anticipate the addition of the second rig will provide additional petrophysical and production data that we will use to reduce drilling and completion costs and improve flow rates as we continue exploiting the Riverbend project."

Upcoming Conference
Gasco management will be presenting at the upcoming Independent Petroleum Association of America Oil and Gas Investment Symposium in New York on April 21, 2004. The Company will be visiting investors in the Midwest during the week of April 12, 2004 and again in the New York area during the week of April 19, 2004.
