                Abraxas Reports Second Quarter 2006 Results with
           Five Consecutive Quarters of Production Growth including a
            41% Increase in Daily Production over Second Quarter 2005

SAN ANTONIO  (Aug. 8, 2006) - Abraxas  Petroleum  Corporation  (AMEX:ABP)  today
reported  financial and  operating  results for the quarter and six months ended
June 30, 2006 and provided an operational update.

Daily  production  from the second  quarter of 2006  increased 5% over the first
quarter of 2006 marking five consecutive quarters of production growth.

Results for the quarter ended June 30, 2006 included:
     o   Production of 2.0 Bcfe, a 41% increase over Q2 2005;
     o   Revenue of $13.3 million, a 38% increase over Q2 2005;
     o   EBITDA (a) of $9.4 million, a 61% increase over Q2 2005; and
     o   Cash flow (a) of $5.3 million, a 117% increase over Q2 2005.

Results for the six months ended June 30, 2006 included:
     o   Production of 3.8 Bcfe, a 42% increase over the same  six-month  period
         of 2005;
     o   Revenue of $26.6 million, a 53% increase over the same six-month period
         of 2005;
     o   EBITDA (a) of $18.6  million,  a 82% increase  over the same  six-month
         period of 2005; and
     o   Cash flow (a) of $10.6 million, a 184% increase over the same six-month
         period of 2005.

         (a) see reconciliation of non-GAAP financial measures below.

Net earnings in the second  quarter of 2006 were  $983,000,  or $0.02 per share,
compared  to a net loss in the same  quarter  of 2005 of  $37,000,  or less than
($0.01) per share, from continuing  operations.  Net earnings for the six months
ended June 30, 2006 were $2.2 million,  or $0.05 per share, as compared to a net
loss during the same six-month period of 2005 of $973,000, or ($0.03) per share,
from  continuing  operations.  Continuing  operations  represent  financial  and
operating  results  from  operations  in the  U.S.  only  as all  of  Grey  Wolf
Exploration   Inc.'s   historical   performance   and  results  are  treated  as
discontinued  operations  as a result of the sale of Grey Wolf  shares  owned by
Abraxas in Grey Wolf's initial public offering that closed on February 28, 2005.
Abraxas  currently  owns less than 1% of the  outstanding  capital stock of Grey
Wolf.

As  anticipated,  basis  differentials  during the  quarter  narrowed  closer to
historical  ranges.  The Company realized an oil differential of less than $1.30
and a gas  differential of 20% to NYMEX (L3D) during the second quarter of 2006,
compared to $1.95 and 30%,  respectively,  that the Company  realized during the
first quarter of 2006.

"I am very  pleased to  announce  that we have  increased  production  from 14.2
MMcfepd to 21.4 MMcfepd  since the first  quarter of 2005.  This 51% increase in
production has been achieved  exclusively  through the drill bit, as we continue
to explore and exploit the many  opportunities  that we have  identified  on our



existing  leasehold.  As a result, we believe we are well positioned to meet our
2006 production guidance," commented Bob Watson, Abraxas' President and CEO.

Operations
In South Texas, the Simek-Cook #1 was recently completed in the Wilcox formation
and placed on-line at approximately 1.0 MMcfepd.

In the  Oates SW Field of West  Texas,  completion  operations  continue  on the
Hudgins  #37-1H,  a horizontal  Devonian  re-entry,  and the La Escalera #5-1, a
Lower  Wolfcamp  test.  The La Escalera #2 is currently  shut-in after the Atoka
formation  was  deemed not  commercial;  this well will be  evaluated  for other
potentially productive zones.

In Wyoming,  some of the  accumulated  oil in  inventory at the end of the first
quarter was sold during the second  quarter,  whereas the remainder will be sold
during the third quarter.  The Company continues to monitor  production rates on
the four  vertical  wells  drilled in late 2005,  while  analyzing the different
fracture treatments employed.

Abraxas owns a 100% working interest in all of the above-mentioned wells.

                  RECONCILIATION OF NON-GAAP FINANCIAL MEASURES


To fully assess Abraxas' operating results,  management  believes that, although
not  prescribed  under  generally  accepted  accounting   principles   ("GAAP"),
discretionary cash flow and EBITDA are appropriate  measures of Abraxas' ability
to satisfy capital  expenditure  obligations  and working capital  requirements.
Cash flow and EBITDA are non-GAAP financial measures as defined under SEC rules.
Abraxas'  cash flow and EBITDA  should not be  considered  in  isolation or as a
substitute for other financial  measurements prepared in accordance with GAAP or
as a measure  of the  Company's  profitability  or  liquidity.  As cash flow and
EBITDA  exclude  some,  but not all,  items that  affect net income and may vary
among companies,  the cash flow and EBITDA presented below may not be comparable
to  similarly  titled  measures of other  companies.  Management  believes  that
operating income (loss)  calculated in accordance with GAAP is the most directly
comparable measure to cash flow and EBITDA;  therefore,  operating income (loss)
is utilized as the starting point for these reconciliations.


Cash flow is defined as operating income (loss) plus depletion, depreciation and
amortization expenses,  non-cash expenses, cash gains (losses) on the settlement
of non-hedge  derivatives  and cash portion of other income  (expense)  and cash
interest.  The  following  table  provides  a  reconciliation  of  cash  flow to
operating income (loss) for the periods presented.
