                     GASCO ENERGY PROVIDES OPERATIONS UPDATE
       THIRD QUARTER NET PRODUCTION UP 56% OVER SECOND QUARTER OF 2005 AND
                       UP 239% OVER THIRD QUARTER OF 2004

DENVER - (PR Newswire) - October 3, 2005 - 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, 2005 was
468.2 million cubic feet equivalent  (MMcfe), an increase of 56% over the second
quarter of 2005  production of 300.2 MMcfe,  and 239% above third quarter 2004's
production  of 138.2 MMcfe.  Net  production  increases  are  attributed  to the
completion  of new wells  during the  quarter  and to a higher  average  working
interest  in those  wells  partially  offset by normal  production  declines  in
existing wells.

Third  quarter 2005 gross  production  increased 43% to 1,238.6 MMcfe over gross
production of 863.4 MMcfe for the second quarter of 2005.

*Includes preliminary production estimates for the third quarter 2005

Drilling Activity
During the third  quarter of 2005 Gasco  spudded  five gross wells (4.3 net) and
reached total depth on five gross wells (4.3 net). The Company  continues to run
three rigs,  which were in the process of drilling  three wells as of the end of
the  quarter.  Year-to-date  Gasco has  spudded  16 gross  wells  (11.1 net) and
reached  total  depth on 14 gross  wells  (9.1 net).  The  Company  believes  it
activity levels keep it on track to drill and complete the previously  announced
target of 20 gross wells (13 net) for the full-year 2005.

Completion Activity
Gasco conducted initial  completion  operations on five wells and re-entered one
well to complete  behind-pipe  pay zones  during the third  quarter of 2005.  At
September 30, 2005, Gasco had 35 gross wells on production, and one well flowing
back frac fluids from recent completion operations. During the first nine months
of 2005, the Company  conducted  initial  completion  operations on 17 wells and
re-entered 9 well bores to complete behind-pipe pay.

Management Comment
Mark Erickson, Gasco's President and CEO, said: "Production growth and continued
success  in the  Blackhawk  Formation  were  two  positives  for  third  quarter

                                       1


operations.  Even  with a  quarterly  production  record,  two  of the  fracture
stimulation   jobs  occurred  late  in  the  quarter  and  did  not   contribute
meaningfully to net production.  These  completions  along with planned activity
for the fourth quarter  should allow Gasco  continued  production  growth in the
fourth  quarter of 2005.  Operationally,  we continue  to focus on refining  our
completion  techniques and reducing drilling days.  Gasco's current plans are to
emphasize  delineation  drilling  to further  define  the  aerial  extent of two
Blackhawk  marine  trends  it has  identified.  To this end,  two rigs  continue
drilling  close-in  field  extension  wells  taking  advantage  of  the  current
commodity  price  environment,  while one rig will be drilling  in less  defined
areas of the Riverbend Project to further extend the play."

Third Quarter Financial Results
Gasco  expects to announce its third  quarter  results on or before  November 9,
2005.  The Company will  schedule a  conference  call to be announced at a later
date to discuss third quarter operational and financial progress.
