                    GASCO ENERGY UPDATES UINTA BASIN ACTIVITY

DENVER - (PR Newswire) - July 11, 2007 - Gasco Energy,  Inc.  (AMEX:  GSX) today
provided an interim  operations  update on its Riverbend Project in Utah's Uinta
Basin.

Record Quarterly Production
Estimated  cumulative  net  production  for the quarter  ended June 30, 2007 was
1,135  million  cubic feet  equivalent  (MMcfe),  an increase of 7.9% over first
quarter 2007  production  of 1,051 MMcfe,  and 32% above second  quarter  2006's
production  of 863  MMcfe.  Utah  operations  constitute  approximately  100% of
Gasco's net production.

The Company  reported an increase in sequential  production  volumes despite its
decision to delay completion activity on its recently drilled wells due entirely
to seasonally low natural gas prices received in the Rockies.  Gasco has elected
to also  curtail  production  from some of its existing gas wells and will bring
this   production    back   online   when   prices   improve.    Curtailed   and
facilities-constrained   net  volumes  for  the  quarter  are  estimated  to  be
approximately  100 MMcf or 1.1 MMcf/d.  Relief from lower regional gas prices is
expected upon additional takeaway capacity exiting Rockies basins,  specifically
with the  January  2008  anticipated  in-service  date of Phase I of the Rockies
Express pipeline.

     *Includes Q207  preliminary  production  estimates.  Company  estimates may
     differ from the actual results to be reported in its forthcoming  filing on
     Form 10-Q for the quarter-ended June 30, 2007.

Drilling Activity
During the second quarter of 2007, Gasco spudded eight gross wells (5.6 net) and
reached  total depth (TD) on six gross  wells (4.4 net) in Utah.  The Company is
currently running three drilling rigs on its Riverbend project.  Average time to
TD on the last 10  Gasco-operated  wells  was 18.6  days.  The  operations  team
continues  to record  excellent  results in the ongoing  initiative  to reducing
drilling days and other project costs that are within its control. Year-to-date,
Gasco spudded 13 gross  operated  wells (10.1 net) and reached total depth on 13
gross wells (9.4 net).  Gasco also  participated  in one  outside-operated  well
(0.25 net),  and had its second well (Non-op;  GSX carried for 20% WI) in Nevada
begin drilling.

Completion Activity
Also during the quarter,  Gasco conducted initial  completion  operations on two
wells (1.5 net),  and  re-entered  no wells to complete  behind-pipe  pay zones.
There were also no outside-operated  wells completed in the quarter.  During the
first six months of 2007, Gasco conducted initial completion  operations on nine


                                       1


operated  wells (6.2 net) and re-entered one operated well (1.0 net) to complete
behind-pipe  pay zones.  The Company also  participated in the completion of one
outside  operated  well (0.25 net).  At June 30, 2007,  Gasco  operated 98 gross
producing  wells  with  eight  additional  wells  awaiting  initial   completion
activities, including the Mancos test, the Federal #14-31. The Company currently
has  an  inventory  of 24  operated  wells  with  up-hole  recompletions.  Gasco
continues  to build its  recompletion  inventory  in advance of what the Company
believes could be a stronger Rockies commodity price environment.

Mancos Shale Test - Riverbend Project, Utah
Completion  operations  commenced on Monday, June 25, 2007 on the Gasco-operated
Federal #14-31 (GSX:  100% WI), a deep gas test drilled to total depth of 16,763
feet to  evaluate  the  productive  potential  of the  Wasatch,  upper and lower
Mesaverde,  Blackhawk,  Mancos and Dakota formations. The deeper Dakota interval
had numerous  sands that were gas charged but tight,  and was  determined  to be
non-commercial.  A cast iron plug was set in the Dakota  allowing for completion
activities in the Mancos Shale.

During initial  completion  work, the  lower-most  Mancos Shale frac stage,  the
first of five stages in the completion  design,  was successfully  hydraulically
fractured.  The completed  interval  flowed back frac fluids and delivered first
gas to sales at an initial  turn-on rate of 1.132  million cubic feet of natural
gas per day while continuing to flow back frac fluid.

While attempting to complete the second Mancos Shale stage, a flow-through  frac
plug became  stuck in the hole at  approximately  4,590 feet.  While  working to
remove the stuck plug, the completion vendor  accidentally fired the perforating
guns at about 4,580 feet  preventing  completing  additional  stages  until well
remediation  is  successfully  concluded.  The stuck  frac  plug has since  been
extricated from the hole. Well remediation is underway with plans to cut-off the
4 1/2 inch casing below the perforation damage and pull out of the hole with the
damaged string.  The accidentally  perforated casing joint will be replaced with
an  overshot  joint  especially  designed to  maintain  17,000 psi.  The well is
currently shut-in while well-bore remediation work is underway.

Upon  completion of the  remediation  process,  which is  anticipated  to take a
month, the Company expects full wellbore  integrity to be restored  allowing the
completion to proceed as originally  planned.  The technique  being employed has
been successfully  utilized previously by industry,  and Gasco engineers believe
it to have a high  probability  of  success.  In the event that the  remediation
design  does not fully  restore the  wellbore,  Gasco  believes  that the vendor
responsible for the damage will  ultimately  bear full financial  responsibility
for the error resulting in this problem, including repairs and remediation.

Mark Erickson,  Gasco's  President and CEO, said: "We are very encouraged by the
initial  flow rates from the lone Mancos Shale  interval in the Federal  #14-31.
However,  the data is inconclusive until we can successfully  fracture stimulate
all five Mancos  stages.  Based on  open-hole  log  analysis,  it is our initial
assessment  that  most of the  remaining  Mancos  zones  appear  to be of higher
quality than the first completion stage. We believe that results to date confirm
our  geologic  model  for the  deeper  gas  pay and  look  forward  to  resuming
completion activities on the well once the remediation work is completed."

Erickson continued: "With respect to shut-in production, given the nature of our
tight-gas  reservoirs,  we are not  forced  to give our gas away at these  lower
prices  when we have  wells that can  essentially  act as  storage  fields.  The
current  shut-in  volumes can  entirely be produced  into sales as prices in the
Rockies improve with winter,  seasonal demand and improved  takeaway capacity in
the Rockies comes on line. We expect to have a large inventory of completion and
recompletion  opportunities  that will allow us to rapidly  increase  production
once pipeline issues are resolved."

Q207 Results
Gasco  expects to announce  its second  quarter  results on August 1, 2007.  The
Company will schedule a conference  call to discuss  financial  and  operational
results, which will be announced at a later date.
