                 GASCO ENERGY PROVIDES RIVERBEND ACTIVITY UPDATE

DENVER - (PR Newswire) - April 13, 2004- 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.

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  Ridge12-32-10-17,  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.
