             GASCO ENERGY PROVIDES RIVERBEND PROJECT ACTIVITY UPDATE

DENVER - (PR Newswire) - August 2, 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.

Drilling Activity
Year to date,  Gasco has drilled six gross wells.  Three have been completed and
are flowing to sales,  one well is flowing back frac fluid and is  continuing to
clean up, and two are awaiting completion.

Near-term  drilling  plans  include  two new  wells in the  Riverbend  Project's
Riverbend Area. One will test the Wasatch and Mesaverde intervals and the second
well will be Gasco's third  Blackhawk  test.  The  Blackhawk  test will evaluate
Blackhawk  potential on the northeastern flank of Gasco's leasehold,  an 11-mile
stepout from the Wilkin Ridge Blackhawk discovery announced in early June 2004.

Increased  drilling  activity has led to decreased  drilling time to total depth
and  improved  overall  performance  and  efficiencies  as Gasco  engineers  and
drilling and service crews continue to perfect  operations by learning from each
well drilled. A well-by-well  comparison for the first five wells is provided in
chronological order.

Riverbend Gas Gathering
Gasco recently  installed  compression  to the previously  announced Gate Canyon
Blackhawk  discovery.  The  addition  of  compression  resulted  in  incremental
additional  production  of  250 - 300  thousand  cubic  feet  per  day  (Mcf/d).
Engineers are encouraged by the production  boost in the well which now averages
700 Mcf/d from the Wasatch, Upper and Lower Mesaverde and Blackhawk intervals.

Company-owned gas gathering assets include 70,000 feet of pipeline with plans to
lay another  53,000 feet of gathering in the  Riverbend  area within the next 60
days.  Gasco  will be adding  compression  to Wilkin  Ridge in the next  several
weeks,  dependent upon compressor  availability.  Engineers continue to evaluate
additional gathering and compression needs in each of the four Riverbend Project
areas: Riverbend, West Desert, Wilkin Ridge and Gate Canyon.

Production

Net  cumulative  production  for second  quarter 2004 was 130 million cubic feet
equivalent (MMcfe).  This is a 20% increase over second quarter 2003 production.
Sequential  quarterly  production  was off 4% from the 136 MMcfe produced in the
first quarter 2004. First half 2004 production of 266 MMcfe was 82% greater than
the 146 MMcfe  produced in the first six months of 2003.  Production on July 29,
2004 was 6.5 MMcfe/d gross and 2.2 MMcfe/d net. The average  price  received for
natural  gas  sales in the  second  quarter  was $5.96  per  Mcfe.  Natural  gas
comprised 94% of Gasco's second quarter and first half production.





Gasco attributes the fractional  decline in net production to normal  production
declines in wells that were brought  online  early in the first  quarter and the
slow pace of  completion  activity as the 2004  drilling  program got  underway.
Long-lived wells marked by hyberbolic  decline deplete rapidly early in the life
of the well and at a much lower rate later in the wells' lives.  Two  additional
wells were brought online late in the second quarter,  the production benefit of
which will be realized in the third quarter.

Management Comment
"Drilling  efficiencies and improving  performance in Riverbend are exactly what
we expected to see," said Gasco CEO and president,  Mark Erickson.  "We have two
rigs running,  move times are improving and we are getting  better at exploiting
our Uinta  Basin  leasehold.  We will soon spud  another  Blackhawk  test in the
Riverbend  Area which will further  delineate the Blackhawk  potential  over our
acreage. Gasco remains on track to drill 13-15 gross wells in 2004, our greatest
activity level in company history"

Upcoming Conference
Gasco  management will be presenting at The Ninth Oil & Gas Conference in Denver
on  Tuesday,  August  3  at  10:00  AM.  Please  visit  the  conference  website
www.theoilandgasconference.com  for a delayed  webcast of CEO,  Mark  Erickson's
presentation. Slides from the presentation are available at www.gascoenergy.com.
