                 GASCO ENERGY PROVIDES INTERIM OPERATIONS UPDATE


DENVER - (PR Newswire) - August 21, 2007- Gasco Energy,  Inc. (AMEX:  GSX) today
provided an interim operations update on its Riverbend Project in Utah.

As previously  announced,  Gasco successfully  completed the Federal #14-31 (GSX
operates with 100% working interest) in five Mancos shale stages.  Upon drilling
out the frac plugs,  the well was turned on at a rate of 4.7 million  cubic feet
of  natural  gas per day  (MMcf/d)  with a casing  pressure  of 7,500  psi and a
flowing tubing pressure of 5,128 psi against a line pressure of 722.1 psi.

During the next 24 hours,  the well flowed back  associated frac fluids and sold
gas to sales of 2.1 MMcf with  approximately  421 barrels of water,  included in
which is primarily frac fluids,  on a 14/64" choke with 2,700 psi flowing tubing
pressure and 4,500 psi flowing casing pressure.

Commenting on the Federal  #14-31,  Gasco Chief Operating  Office,  Mike Decker,
said,  "We are pleased with the results from the Mancos pay. The initial gas and
fluid rates are in line with what we had modeled for our first Mancos test.  The
results  are also in line with other Uinta Basin  operators'  Mancos  production
data that is now becoming available through Utah state agencies.  After thorough
monitoring and analysis of production attributes and reservoir  characteristics,
we plan to re-enter the well to further complete the uphole pay which is present
in the Wasatch, Mesaverde and Blackhawk formations."
