NEWS RELEASE / FOR RELEASE AT 9:00 AM EST, TUESDAY, DECEMBER 23, 2003

                      GASCO ANNOUNCES RIVERBEND COMPLETIONS
                      LYTHAM FEDERAL 22-22 IPS AT 2.3MMCFD

DENVER - (PR Newswire) - December 23, 2003 - Gasco  Energy,  Inc. (OTC BB: GASE)
today  provided an interim  operational  update on oil and gas activities on its
Riverbend Project in Utah's Uinta Basin.

LYTHAM FEDERAL 22-22 (GASCO-OPERATED: APPROXIMATELY 70% WI)
Gasco is pleased to announce that it successfully  completed eight stages over a
gross interval of greater than 4,700 feet in the Wasatch and Mesaverde sections.
During a 24-hour test, the well had initial  potential of 2.3 million cubic feet
of natural gas per day (MMcfd) with  initial  flowing  tubing  pressure of 2,100
psi,  utilizing a 26/64 inch choke.  The well was  constrained at the surface by
the production equipment.  Associated fluid production was 360 barrels of water,
consisting almost entirely of frac fluid, and four barrels of condensate.

FEDERAL 32-31 (GASCO-OPERATED: APPROXIMATELY 80% WI)
All  Mesaverde  and Wasatch pay in the Federal  32-21 has been fully  completed.
Initial production for the well during the first 24 hours was approximately 1.26
MMcfd.  The well is now flowing gas to sales and is notable because it is one of
the lowest-cost completions performed by Gasco in the Uinta Basin.

Using  the  Schlumberger   proprietary  PowerSTIM*  well  optimization  service,
Schlumberger  and Gasco  personnel  collaborated  to evaluate the  reservoir and
design cost-efficient, high productivity completions for these two wells.

Commenting  on the  successful  implementation  of the PowerSTIM  process,  Gary
Kolstad,  Schlumberger Vice President for US Land said, "This is another example
of a successful  PowerSTIM  implementation  in tight gas  reservoirs.  PowerSTIM
integrates  the  technical  and economic  considerations  of the  reservoir  and
delivers exemplary results for our Clients."

The Lytham  22-22 and the  Federal  32-31 are the first two wells  completed  by
Gasco using Schlumberger's  technique to complete all available wellbore net pay
in one completion  process.  Schlumberger  has been  successful in applying this
technique in several other fields and basins.

MANAGEMENT COMMENTS
Commenting on Uinta Basin  operations,  Gasco CEO and  President,  Mark Erickson
said: "The Lytham Federal 22-22 appears to be a commercial success. While we are
excited about the early results,  we are monitoring its progress and are working
to  resolve  the  surface  constraints  that can come with wells that IP at much
higher  rates than  anticipated.  The bigger  lesson to be taken from the Lytham
22-22  is  that  engineering  and  completions  techniques  are  so  vital  to a
successful  well in these  tight gas sands.  We are  pleased to be working  with
Schlumberger's  talented team.  They are bringing a whole new thought process to
Uinta completion design. We admire their progressive ideas and focus on lowering
per-unit  development  costs and will work  together to improve cost savings and
initial  production rates for the wells drilled in the 2004 program.  It is good
timing to have  additional  gas  flowing  to  sales.  Gasco is  unhedged  and is
benefiting from seasonally  constricted Rocky Mountain price differentials.  Our
average  wellhead price for December  through today is ranging between $5.25 and
$6.00 Mcfe."
