                                       1


In accordance  with SEC  requirements,  Gasco's proved  reserves at December 31,
2008 were computed using  unescalated  year-end 2008 commodity  prices (based on
Rocky Mountain  regional  prices) of $23.60 per barrel for black wax, $14.33 per
barrel for  condensate and $4.63 per million  British  thermal units for natural
gas including  necessary  adjustments  for quality and location to arrive at the
net price received by the Company as of December 31, 2008. The average price net
to Gasco in the  reserve  report is $15.34 per barrel for  liquids and $4.63 per
Mcf for natural gas. Based on these prices the estimated  discounted net present
value of Gasco's proved reserves, before projected income taxes, using a 10% per
annum  discount  rate  ("PV-10")  was $69.5  million at December 31,  2008.  For
December 31, 2007, the SEC PV-10 number was $161.8 million and used net year-end
commodity  prices of $6.53 per Mcf of natural gas and $73.95 per barrel of crude
oil.

All of the  reserves  valued in the  report are  located  in  Gasco's  Riverbend
Project  area in Carbon,  Duchesne,  and Uintah  Counties in Utah's Uinta Basin.
Reserve   estimates  are   engineered  by  independent   reservoir   engineering
consultants, Netherland, Sewell & Associates, Inc. and conform to the definition
as set  forth  in the SEC  Regulation  S-X Part  210.4-10  (a) as  clarified  by
subsequent Commission Staff Accounting  bulletins.  The proved reserves are also
in  accordance  with  Financial  Accounting  Standards  Board  Statement  No. 69
requirements.  In  accordance  with SEC  guidelines,  reserve  estimates  do not
include  any  probable  or  possible   reserves  which  may  exist  for  Gasco's
properties.

While the Company has not completed its December 31, 2008  financial  statements
including its valuation of unproved properties, management does not believe that
the Company will record an impairment charge of the carrying value of its proved
oil and gas properties for the fourth quarter 2008.

Important  definitions  pertaining  to oil and gas  reserves may be found in the
"Glossary of Natural Gas and Oil Terms" in the  Company's  annual Filing on Form
10-K.

2009 Initial Capital Expenditure Budget
Gasco also today  announced  that its Board of Directors  has approved a revised
initial  2009  capital  expenditure  budget  (CAPEX)  of $10  million.  From the
preliminary budget presented in a November 4, 2008 news release, the Company has
reduced its CAPEX budget for 2009 by $20 million. The change in plan is a direct
result of further weakening in commodity prices, high service costs for drilling
and completing wells and limited capital  markets.  The revised program includes
completing  the Gate  Canyon  State  #23-16,  the  drilling  and  completion  of
approximately two gross (0.84 net) wells and 12 recompletions (4 net) of up-hole
zones on Gasco's Riverbend Project located in the Uinta Basin of Utah. The wells
in the program will be drilled to develop the  natural-gas-bearing  upper Mancos
shale  intervals and associated  up-hole pay zones in each  wellbore.  The CAPEX
budget does not include possible  acquisitions,  but may include installation of
pipeline   infrastructure,   distribution  facilities  and  certain  geophysical
operations.

The  Company  intends  to fund  its  budget  entirely  through  cash  flow  from
operations.  Consequently,  the  Company  will  monitor  spending  and cash flow
throughout  the  year  and may  accelerate  or  delay  investment  depending  on
commodity prices and cash flow  expectations.  The Company currently  operates a
single rig. This rig will be released after it completes drilling  operations on
the well it is currently drilling.  It is scheduled to reach total depth (TD) in
late  February  2009.  At rig  release,  the Company is obligated to pay the rig
contractor  approximately  $4.6  million for early  termination  of the drilling
contract (as calculated at $12,000/day  from rig release through March 15, 2010,
the expiration date of the contract).

Gasco has a $250 million reserve-based  revolving line of credit facility with a
borrowing  base of $45  million,  of which $31 million was drawn at December 31,
2008.

Interim Gate Canyon Area Update
The GCS #23-16 (25% working interest,  Gasco operated), a Dakota and full Mancos
shale interval  test,  reached TD of 16,610 feet on June 13, 2008. As previously
announced,  the well was  completed in the Morrison and Dakota  formations  with
four frac stages, where it encountered mechanical issues.

                                       2


After  setting a bridge  plug above the Dakota to  isolate  production  from the
lower intervals, completion operations have subsequently moved up-hole to target
Mancos  Shale and  Blackhawk  pay.  Gasco  has now  successfully  completed  two
additional frac stages, the fifth and sixth stages in the wellbore.  The initial
two lower Mancos stages (five and six) were  initially  tested at combined rates
of up to 4.2 million cubic feet of natural gas per day (MMcf/d),  with a flowing
casing pressure of 7,700 psi on a 12/64" choke.  During a 12-hour test, the well
averaged a  combined  flow-rate  of 2.5 MMcf/d on a 12/64"  choke with a flowing
casing pressure of 4,900 psi. All production  rates were observed while the well
was cleaning up and flowing back frac fluid.  Gasco is currently  moving up-hole
to complete  seven  additional  Mancos / Blackhawk  frac stages.  At that point,
production   testing  will  resume  before  completing  and  testing  additional
Blackhawk, Mesaverde and Wasatch pay zones located further up-hole.

Management Comment
Gasco's  President and CEO Mark  Erickson  said:  "The high flow rates  observed
during the early stages of our Gate Canyon well are encouraging initial signs of
the GCS #23-16 productive  potential.  There remains  additional  up-hole pay to
complete in the well,  which should allow us to learn more from the  completions
and  further  production  testing.   The  results  are  early,  but  indicate  a
gas-charged  system at least in this part of Gate  Canyon.  We have  focused the
majority of our historical drilling program and CAPEX in the eastern part of the
Riverbend  project and have  limited  drilling and  completion  data and results
to-date from the Gate Canyon Unit located to the extreme west of our  leasehold.
The well  should  give us a good  look at  reservoir  characteristics  and other
important data to help us better understand the Gate Canyon area.

"With respect to reserves, the drop in commodity prices along with high services
costs did not allow us to  clearly  demonstrate  the  critical  improvements  we
continue to achieve on our  Riverbend  Project.  Our  revisions of 46.6 Bcfe are
attributed  to lower  prices  received  and higher well costs  during 2008 which
resulted  in the  booking  of no proved  undeveloped  (PUD)  locations.  We also
experienced a write down of 290,000 barrels, or 88% of our Black Wax production,
attributed  again  to the  sharply  lower  price at  December  31,  2008.  It is
interesting to note that during 2008 the Company drilled and completed six wells
that were  previously  booked as PUD  locations  in 2007.  The proved  developed
producing  reserves resulting from this drilling yielded an average of 2.52 Bcfe
per well versus the previously PUD assigned  reserves  averaging 1.75 Bcfe, or a
44% increase over the PUD estimates.

Erickson  concluded:  "Now, in 2009, we are  experiencing  softening of services
costs which should  benefit our planned  2009  program.  During 2008,  all wells
drilled  penetrated  the Mancos which expanded our core producing area to nearly
one full township. We continued to work diligently to reduce drilling days while
constantly improving tight gas sands and shale completion techniques. Production
analysis  indicates that we are often draining less than an estimated five acres
within the Mancos.  We are greatly  benefitted  by our thick Mancos  section and
additional up-hole pay zones that can be commingled with the Mancos. The play is
clearly ready for the  implementation  of new technology,  including  horizontal
drilling which has proven successful in other shale plays in North America."
