            Abraxas Reports Fourth Quarter and Full-Year 2004 Results

SAN  ANTONIO  (March  23,  2005) -  Abraxas  Petroleum  Corporation  ("Abraxas")
(AMEX:ABP) today reported financial and operating results for the fourth quarter
and year-ended  December 31, 2004. As a result of the Grey Wolf Exploration Inc.
("Grey Wolf") initial public offering  ("IPO") that closed on February 28, 2005,
the  information   herein  represents   financial  and  operating  results  from
operations  in the U.S.  only as all of Grey Wolf's  historical  performance  is
treated as a discontinued operation.

Production of 5.8 Bcfe for the year generated  revenues of $33.9 million and net
income of $7.8  million  or $0.22 per share  from  continuing  operations.  This
compares to a net loss from continuing  operations of $14.1 million or $0.40 per
share for the prior year ended  December 31, 2003.  Abraxas posted net income of
$17.0 million ($0.47 per share) in the fourth quarter of 2004 compared to a loss
of $3.4 million  ($0.10 per share) in the same  quarter of 2003 from  continuing
operations.  The net income in the fourth quarter of 2004 (and  full-year  2004)
included a $12.6  million gain on  redemption  of debt booked as a result of the
refinancing  completed  in  October  of 2004 and an income  tax  benefit of $6.1
million  related to the gain on the sale of the Grey Wolf  shares  that  Abraxas
owned. The actual gain on the sale of the Grey Wolf shares will be booked in the
first  quarter of 2005 and will  include a similar  income  tax  expense of $6.1
million.

The most significant items related to 2004 results included:

     o   Restricted  capital  spending of $9.3 million during 2004, over half of
         which was spent in the  fourth  quarter,  compared  to $9.2  million in
         2003;
     o   Daily production rates declined a modest 6% amid capital restrictions;
     o   Realized price per Mcfe of $5.72 in 2004 compared to $4.82 in 2003;
     o   Global refinancing completed in October; and
     o   Preparation for expanded budget in 2005.

Subsequent to year-end,  as a result of the secondary  shares sold by Abraxas in
the Grey Wolf IPO,  outstanding  indebtedness  under Abraxas' $25 million bridge
loan was reduced to approximately $5 million.

"For Abraxas,  2004 was a year of preparation - for a stronger balance sheet and
an expanded capital budget. So far, in 2005, we have  significantly  reduced the
leverage on our balance  sheet to a manageable  level through the Grey Wolf IPO,
and kicked off our capital development program with 6 wells in various stages of
drilling and completion," commented Bob Watson, Abraxas' President and CEO.

                  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 most similar to cash flow and EBITDA.


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.
