GASCO ENERGY UPDATES UINTA BASIN ACTIVITY

DENVER - (PR Newswire) - October 10, 2007 - Gasco Energy, Inc. (AMEX: GSX) today
provided an interim operations update on its Riverbend Project in Utah's Uinta
Basin.

Quarterly Production
Estimated cumulative net production for the quarter ended September 30, 2007 was
990 million cubic feet equivalent (MMcfe) a 4.5% increase over the third quarter
of 2006. Gasco has elected to curtail its Utah production operations, which
constitute approximately 100% of its net production, due to low gas prices which
averaged $2.93 per MMBtu during the quarter. Significant price differentials
associated with limited pipeline capacity and increasing regional supply has
resulted in low Rocky Mountain prices, specifically in the Uinta Basin. Given
the current takeaway capacity, Gasco has delayed completions in new wells and
up-hole recompletions in existing wells. The Company expects to increase
activity during November and December as natural gas prices are expected to
rebound with increased winter demand.

Gasco reported an increase in year-over-year quarterly production volumes
despite its decision to curtail production and delay completion and
re-completion activity. Curtailed and facilities-constrained net volumes for the
quarter are estimated to be approximately 130 MMcf, or 1.4 MMcf/d.

Drilling Activity
During the third quarter of 2007, Gasco spudded eight gross wells (2.0 net) and
reached total depth on nine gross wells (2.4 net) in Utah. All of these wells
were drilled to target the Blackhawk Spring Canyon trend. Of these eight wells,
Gasco elected to drill two wells into the deeper Mancos Formation. One well,
targeted the Upper Mancos shale and the second targeted approximately one half
of the Mancos Shale interval. The second well, the Federal 21-19, was drilled to
a total depth of 14,800 feet and penetrated approximately 1,950 feet of Mancos
interval. This well was drilled in 20.5 total days from surface casing to total
depth, averaging 722 feet per day. This was a 7% improvement, when compared to
the average drilling time of 19 days achieved for the last 10 wells drilled to
the Blackhawk Spring Canyon formation at approximately 12,800 feet, for an
average of 673 feet per day. The Company is currently running three drilling
rigs on its Riverbend project. Two of these are capable of drilling
significantly into the Mancos Formation. Gasco is evaluating the testing of the
Mancos Shale on a well-by-well basis.

Completion Activity
During the quarter, Gasco conducted initial completion operations on five
operated (2.8 net) wells. During the first nine months of 2007, Gasco conducted
initial completion operations on 14 operated wells (8.0 net) and re-entered one
operated well to complete behind-pipe pay zones. The Company also participated
in the completion of one outside operated well (0.25 net). At September 30,
2007, Gasco operated 103 gross producing wells and currently has an inventory of
10 operated wells awaiting initial completion operations and 28 operated wells
with up-hole recompletions.

Mancos Shale Test - Riverbend Project, Utah
Gasco's Federal #14-31 (100% working interest) was spud during the second
quarter of 2007 and was completed in five Mancos shale stages in August. Gasco
currently estimates potential reserves from the Mancos interval at 1.2 to 2.0
Bcfe. From its preliminary analysis, Gasco believes that approximately 67% of
the production from the Mancos shale in our area is from the upper half of the
Mancos formation. The Federal 21-19 was drilled to a depth of 14,800 feet based
on this analysis. The 21-19 was drilled about 2.5 miles north of the initial
Mancos test, the Federal 14-31, and preliminary results indicate a similar
geologic section and an equal amount of natural fracturing as the upper Mancos
in the Federal 14-31. This test resulted in only 4.5 days of incremental
drilling with a total cost to drill and log of $250,000, as estimated from daily
drilling records. We expect the well to require three stages of fracing in the
Upper Mancos interval with an estimated completion cost of $750,000 to $800,000
bringing the total cost to drill and complete this incremental interval to $1.00
to $1.25 million for reserve potential of .75 to 1.5 Bcf.

Mark Erickson, President and CEO said: "We continue to see significant
reductions in drilling time along with lowering overall completed well costs.
Rig 99 is on the verge of setting new drilling time records as crews become
better trained and more familiar with the modern rig's operating capabilities.
The Mancos continues to prove itself. The first well's production is holding up
well. The recent well drilled faster than we projected and identified
extensively fractured intervals in the upper half of the Mancos. These results
support our belief that we can add significant production and reserves from this
interval with finding costs below what we have historically experienced. We're
excited about the opportunity to expand the Mancos program as we go forward."

Third Quarter 2007 Results
Gasco expects to announce its third quarter results on November 1, 2007 and will
schedule a conference call to discuss those results. Details of the call will be
announced at a later date.
