                Gasco Energy Announces Gate Canyon Drilling Plans
                     And Provides Riverbend Activity Update

DENVER - (PR  Newswire) - December 2, 2003 - Gasco  Energy,  Inc. (OTC BB: GASE)
today  provided an interim  operational  update on oil and gas activities on its
Uinta Basin leasehold including the Gate Canyon Area.

Gasco Gate Canyon State 31-21 (Gasco-operated: 100% WI)
Gasco has  scheduled  a re-entry  of the Gate  Canyon  State  31-21 in  southern
Duchesne    Co.,    Utah.     (please    see    attached    locator    map    at
http://www.gascoenergy.com/gatecanyon.html.  The  Gate  Canyon  State  31-21  is
designed to continue the  exploitation of the Uinta Basin's  basin-centered  gas
accumulation and the western extent of Gasco's acreage.  The well is expected to
begin  drilling  before the end of 2003 and is  permitted  to 11,500  feet total
depth.  By drilling this well,  Gasco earns the rights to 1,560  additional  net
acres of all depths.  Gasco can earn an additional 2,525 net acres of all depths
by spudding a second well one year from the rig release of the Gate Canyon State
31-21.

The Gate  Canyon  31-21  will test  natural  gas  potential  of three  important
potentially   productive  intervals,   the  Wasatch,   Mesaverde  and  Blackhawk
formations.  The Blackhawk Formation is located just below the Castlegate Member
of the Lower Mesaverde at approximately  10,300 feet to 11,700 feet in this part
of the Uinta Basin. Company engineers expect that testing the Blackhawk will add
five to10 days to the drilling schedule and could yield  incremental,  estimated
net reserve additions of 0.60 Bcfe to 1.0 Bcfe.

The well,  located  approximately  25 miles  southwest of Gasco's core Riverbend
Project,  will continue to create the footprints of economic  development across
Gasco's extensive acreage position.  Increased  drilling activity by independent
operators is ongoing on acreage adjacent to Gasco's. The Gate Canyon State 31-21
is an offset location to a Texaco  wellbore that was drilled in the 1960s.  Logs
from the original  Texaco well  indicate gas pay in the Wasatch,  Mesaverde  and
Blackhawk.  Gasco  engineers,  along with  third-party  engineers,  believe that
modern frac  techniques  when applied to these pay zones can help  significantly
increase production as compared to the technology available in the 1960s.

                                       1


Lytham Federal 22-22 (Gasco-operated: 70% WI)
Utilizing  the  less  expensive,   potentially  more  effective  Induced  Stress
Diversion (ISD) fracture  technique for the first time, Gasco engineers  working
with third-party  engineers,  developed a fracture  stimulation  program for two
stages in the lower Mesaverde of the Lytham Federal 22-22.  Initial results from
these two stages are  considered  to be very  successful.  Frac  fluids  rapidly
flowed back from the formation after  completion,  and the well has been selling
gas to sales  since  November  8. Flow rates from the well are  currently  being
stabilized.  In order to  complete  all of the net pay in the well,  the  Lytham
Federal 22-22 has six frac jobs  remaining,  which are scheduled to be completed
by  December  5, 2003.  The six frac jobs will be  completed  using a mixture of
flow-through plugs and ISD. This will be the first time Gasco has simultaneously
completed all of a wellbore's pay.

Successive,  multiple  completions  is a  technique  that  is  used  with  great
effectiveness in Wyoming's Pinedale Anticline and Jonah Field, which are similar
in that those fields are marked by tight gas, basin-centered  accumulations.  If
successful,  the  combination of ISD and  flow-through  plugs should improve the
economics by saving time to complete a well and by substantially  higher initial
production rates which can lead to quicker pay out on the well.

Federal 32-31 (Gasco-operated: 80% WI)
All Mesaverde and Wasatch pay in the Federal 32-21 has been fully  completed and
the well is  currently  flowing  back frac fluids and  cleaning up. The well was
frac'd  utilizing slick water as opposed to gels and is the first time Gasco has
used  this  technique.  Slick  water is  being  successfully  utilized  by major
operators  completing  the Mesaverde  and Wasatch  sands in Colorado's  Piceance
Basin,  which is a tight gas,  basin-centered  accumulation  bordering the Uinta
Basin.  Successful  use of slick water in Riverbend  should further help improve
the economics of marginal  wells  encountered in the area because frac costs may
be reduced by as much as 75%.  First  sales of natural  gas is  expected  by the
middle of December.

Federal 42-49 (Gasco-operated: 30% WI)
The 42-49 has been completed in the Lower Mesaverde and is flowing gas to sales.
Gasco is scheduled to add the Upper  Mesaverde  (Dark Canyon) in early  December
with the  remainder of the Wasatch pay scheduled to be completed by December 15,
2003.  The  Wasatch  Formation  will  be  completed  as a  six-stage  completion
utilizing  coiled  tubing.  Coiled  tubing is expected to save  capital  through
operational  efficiencies,  allowing individual  treatment of Wasatch pay sands.
This  technique  is being  effectively  utilized by major  operators  completing
Wasatch sands in the Piceance Basin.

Federal 23-21 (Gasco-operated: 30% WI)
The 23-21 has also  been  completed  in the  Lower  Mesaverde  and is  currently
producing gas to sales.  Gasco will be adding the Upper  Mesaverde (Dark Canyon)
and a single Wasatch zone in early December.  These two stages will be completed
utilizing the more traditional  style frac plug and gels.  Potentially  three to
five  additional  zones are possible in the Wasatch  depending on the results of
the initial Wasatch completion.


Management Comments
Commenting on Unita Basin  operations,  Gasco CEO and  President,  Mark Erickson
said:  "Gasco's  sizeable  Uinta Basin acreage  position  provides us with ample
drillable  locations.  We have  evaluated the Gate Canyon area for some time and
feel we have the data needed to test these three hydrocarbon  bearing zones, the
Wasatch,  Mesaverde  and  Blackhawk.  The Gate  Canyon  State  31-21 well should
provide Gasco with additional geological data about this part of our leasehold.

"Gasco's  exploitation  and  production  program  is  based on  engineering  and
ever-developing  completion technology. The company seeks to drive down drilling
and completion costs through  improved  efficiencies in every stage of the well.
Our  utilization  of ISD,  coiled  tubing and slick  water are good  examples of
teaming  up with  oilservice  providers  to create  cost-saving  techniques.  We
estimate that if successful over a wider well sampling,  capital savings through
the ISD  technique  alone could be as high as 40% to 50% per well  completion or
25% of the total drill and complete  cost of  approximately  $2 million.  We are
carefully  monitoring  the continued  completion of the Lytham Federal 22-22 and
the other wells. We will update investors when the wells are fully completed and
are flowing commingled production to sales."
