                   GASCO ENERGY ANNOUNCES SECOND QUARTER 2007
                        FINANCIAL AND OPERATIONAL RESULTS

DENVER - August 1, 2007 - (PRNewswire) - Gasco Energy (AMEX: GSX) today reported
its financial and operating results for the quarter ended June 30, 2007.

Financial Results

For the second  quarter 2007,  Gasco  reported a net loss of $66.3  million,  or
$0.70 per share,  as  compared  to a net loss for the same period in 2006 of $53
million,  or $0.62 per  share.  All per  share  figures  are basic and  diluted.
Included  in the  quarter's  operating  expenses  is a non-cash  charge of $64.3
million  related  to an  impairment  of  the  carrying  value  of  oil  and  gas
properties.  Before the impairment charge, Gasco would have posted a net loss of
$2 million or $0.02 per share.


The charge also results in a decrease in total assets.  At June 30, 2007 Gasco's
total  assets were $118  million,  as compared to $165  million at December  31,
2006.

Under the full cost method of accounting, capitalized oil and gas property costs
less accumulated depletion and net of deferred income taxes (full cost pool) may
not exceed an amount equal to the present value, discounted at 10%, of estimated
future net  revenues  from  proved  oil and gas  reserves  less the future  cash
outflows associated with the asset retirement obligations that have been accrued
in the  balance  sheet  plus the cost,  or  estimated  fair  value,  if lower of
unproved properties and the costs of any properties not being amortized, if any.
Should the full cost pool exceed this ceiling, an impairment is recognized.  The
present value of estimated  future net revenues is computed by applying  current
oil and gas prices to estimated future production of proved oil and gas reserves
as  of  period-end,  less  estimated  future  expenditures  to  be  incurred  in
developing  and  producing  the proved  reserves  assuming the  continuation  of
existing economic conditions.  However, subsequent commodity price increases may
be utilized to calculate the ceiling value.

Commenting on the impairment,  Gasco CEO and President Mark Erickson said: "This
is an accounting  requirement  to which we must adhere as a full-cost  reporting
company.  As of June 30,  2007 oil and natural gas prices were $54.09 per barrel
and $3.90 per thousand cubic feet (Mcf). Included in the charge is $10.2 million
attributed to our Wyoming leasehold. The natural gas price at which we would not
have been required to take a ceiling test impairment is $5.82 per Mcf."

Total  revenues were up 6% to $6.1  million,  as compared to $5.8 million in the
second  quarter 2006.  The increase in total revenue is attributed to higher oil
and gas production offset in part by lower commodity prices received and reduced
interest income during the second quarter 2007.

Oil and gas sales for the second  quarter  2007 were $5.1 million as compared to
$4.6  million for the same period in 2006,  an  increase of 11%,  attributed  to
higher  production  volumes.  Gathering  revenues grew to $0.5 million from $0.4
million in 2006.  The revenue  growth is  attributed  to  increased  natural gas
throughput in the system.

Lease  operating  expense  (LOE) for the quarter  decreased to $0.8 million from
$0.9 million in the second  quarter  2006.  The decrease in LOE is attributed to
reduced water hauling charges as a result of a fully operational evaporation pit
to handle water disposal in an environmentally  responsible manner.  Also, fewer


                                       1


workovers in the 2007 period offset in part by modestly higher  production taxes
contributed  to the reduced LOE for the quarter as compared to the same  quarter
in 2006.  On a per-unit  basis,  LOE for the second  quarter  2007 was $0.71 per
thousand  cubic feet of natural gas  equivalent  (Mcfe) as compared to $1.00 per
Mcfe for the same period in 2006.

Due to increased throughput volumes, gathering expense increased to $0.5 million
from $0.4 million in the same period in 2006.

The Company also lowered its general and  administrative  expense  (G&A) to $2.2
million in the second  quarter of 2007 from $2.6  million in the same  period in
2006.  The 15% decrease in G&A expense for the quarter is primarily due to lower
consulting  and legal  expenses  partially  offset by the  hiring of  additional
personnel.  G&A  expense  includes  $0.9  million in expenses in the 2007 period
related to employee  share-based  compensation,  a non-cash  item. On a per-unit
basis,  G&A for the second  quarter 2007 was $1.97 per Mcfe as compared to $3.00
per Mcfe for the same  period in 2006.  Exclusive  of  stock-based  compensation
expense, G&A for the second quarter was $1.19 per Mcfe.

Depletion,  depreciation and amortization (DD&A) was $3.4 million for the second
quarter of 2007 as compared to $2.9 million for the same period in 2006.

Six-Month Period
Gasco reported a net loss attributable to common shareholders for the six-months
ended June 30, 2007 of $66.5 million,  or $0.74 per share,  as compared to a net
loss for the second half of 2006 of $53.2 million, or $0.62 per share.  Included
in both periods'  operating expenses are the non-cash charges of $64 million and
$51 million,  respectively,  related to the  impairment of the carrying value of
oil and gas properties as discussed above.

Total  revenues  decreased  4% to $12.5  million for the first half of 2007,  as
compared to $13 million in the same period in 2006.  For the first half of 2007,
gathering  system revenues and interest income accounted for $1 million and $0.3
million, respectively.

Oil and gas sales for the first half of 2007 were $11  million,  as  compared to
$10.5  million  for the same  period in 2006.  Net cash  provided  by  operating
activities  for the first  half of 2007 was $4.7  million  as  compared  to $4.3
million for the same period in 2006.

At June 30,  2007,  cash and  investments  were $9  million as  compared  to $23
million at December 31, 2006.

Long-term  debt was $12 million at June 30, 2007 as compared to zero at December
31,  2006.  The  Company  currently  has a $250  million  credit  facility  with
JPMorgan,  of which $37 million is available  for  borrowing  capacity and $12.0
million is drawn.

Record Production Volumes
For the second quarter of 2007,  Gasco posted  production of 1,124 million cubic
feet of natural gas equivalent (MMcfe),  versus 863 MMcfe for the second quarter
2006,  an  increase  of 30%.  The average  price  received  for sales of Gasco's
natural  gas and  liquids  was $4.31  per Mcf and  $49.34  per  barrel of liquid
hydrocarbons  for the second  quarter  2007.  This compares to $5.18 per Mcf and
$59.40 per barrel for the same period in 2006.

In the first half of 2007,  Gasco posted record  first-half  production of 2,175
MMcfe  versus 1,764 MMcfe for the first half of 2006,  a 23%  increase.  For the
first-half 2007, the average price received for sales of Gasco's natural gas and
liquids  was $4.88 per Mcf of gas and $47.71 per barrel of liquid  hydrocarbons.
This  compares  to $5.86 per Mcf and  $58.36  per barrel for the same first half
period in 2006. The Company has no hedges in place.

Subsequent Events
     -    Mancos Well  Update.  All five of the Mancos frac stages have now been
          completed.  The composite frac plugs are currently  being drilled out.
          The  Federal  14-31 had an  initial  sales rate of 3,473  Mcf/d,  with
          associated  frac fluid,  after the  remaining  four Mancos stages were
          completed  The initial  Mancos  stage  flowed at 1,132  Mcf/d,  and is
          currently  below a bridge  plug which  allowed  for the repairs to the
          well bore.  More detailed  flow rates and  pressures  will be obtained
          once all of the plugs are drilled out.

     -    Drilling  Partner.  In a separate news release today,  Gasco announced
          that a subsidiary of NFR Energy,  LLC has agreed to  participate  in a
          30-well  drilling  program  operated  by  Gasco.  NFR will earn 67% of
          Gasco's interest in each well by paying NFR's  proportionate  share of
          the  cost  of the  well  plus  certain  fees  and  thereby  earning  a
          proportionate interest in the 40-acre drilling location.

     -    Seismic update.  Approximately 100 linear miles of high resolution 2-D
          seismic  have been shot by CGG Veritas in the  eastern  portion of the
          Riverbend   Project   area,   and  are  currently   being   processed.
          Additionally, about 90 linear miles are expected to be shot by the end
          of the third quarter. Seismic is expected to help delineate structural
          features  and  provide  further  definition  of the  Blackhawk  marine
          trends.
