         Abraxas Reports Fourth Quarter and Full Year 2005 Results with
           Three Consecutive Quarters of Production and Revenue Growth

SAN ANTONIO (March 6, 2006) - Abraxas  Petroleum  Corporation  (AMEX:ABP)  today
reported financial and operating results for the quarter and twelve months ended
December 31, 2005 and provided an operational update.

Production of 1.8 Bcfe for the fourth  quarter of 2005  generated:

         o Revenue of $17.0 million, a 20% increase over Q3 2005;
         o EBITDA (a) of $11.0 million, a 10% increase over Q3 2005; and
         o Cash flow (a) of $7.2 million, a 14% increase over Q3 2005.

Production of 6.1 Bcfe for the year generated:

         o Revenue of $48.6 million, a 44% increase over 2004;
         o EBITDA (a) of $31.3 million, a 60% increase over 2004; and
         o Cash flow (a) of $17.3 million, a 71% increase over 2004.

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

Net income in 2005,  from continuing  operations,  of $6.3 million (or $0.16 per
share) compares to a net loss in 2004 of $9.6 million (or $0.26 per share), from
continuing operations,  excluding the income tax benefit in 2004 of $6.1 million
related  to the Grey  Wolf IPO and the  $12.6  million  gain on debt  redemption
booked as a result of the  refinancing  completed in October of 2004. Net income
in 2005,  including  discontinued  operations,  of $16.9  million  (or $0.43 per
share)  compares  to net income in 2004 of $12.4  million  (or $0.34 per share),
including discontinued operations.

Continuing  operations represent financial and operating results from operations
in the U.S. only as all of Grey Wolf Exploration Inc.'s ("Grey Wolf") historical
performance  and results  from the sale of Grey Wolf shares  owned by Abraxas in
its initial  public  offering  ("IPO")  that closed on February  28,  2005,  are
treated as discontinued  operations.  Abraxas currently owns less than 1% of the
outstanding capital stock of Grey Wolf.

As previously announced, the Company adopted the fair value method of accounting
for stock-based  compensation under Statement of Financial  Accounting Standards
No. 123,  as revised  ("SFAS  123R"),  during the fourth  quarter of 2005.  This
adoption  resulted  in  the  reversal  of  $9.7  million  of  previously  booked
stock-based  compensation  expense under historical  accounting  methods and the
incurrence  of an expense of $587,000  to account for the  adoption of SFAS 123R
for the years 2003,  2004 and 2005.  The positive  impact to net income is, $7.1
million  in the fourth  quarter of 2005  (which  offset a $7.3  million  expense
incurred  during the first  three  quarters of 2005),  $1.2  million in 2004 and
$878,000 in 2003. As SFAS 123R permits for comparative purposes, the Company has
retrospectively presented the financial statements for 2003 and 2004.




"As 2004 was a year of preparation for an expanded  capital  expenditure  budget
and a stronger  balance  sheet,  2005 was a year of  increasing  production  and
revenue.  For three  consecutive  quarters,  we have  increased  production  and
combined with higher  commodity  prices,  increased  revenue over 115% since the
first quarter of 2005. These consecutive production increases are a testament to
the quality of our asset base and the ability of our  technical  team to execute
when given the  capability  to spend  capital  dollars,"  commented  Bob Watson,
Abraxas' President and CEO.

The Company has adjusted its previously  issued 2006 guidance for  depreciation,
depletion  and  amortization  (D/D/A) from $1.30 per Mcfe to $1.50 per Mcfe as a
result of the  December  31,  2005  reserve  report  prepared  by  DeGolyer  and
MacNaughton,  which reflects the increase in future estimated drilling costs for
proved  undeveloped  reserves that has occurred  across the industry  during the
past year.

Operations
In the Oates SW Field of West Texas,  the  Company's  workover rig  continues to
clean out the vertical section on a Devonian re-entry well, which after reaching
approximately  12,500',  the Company  plans to drill  horizontally.  The Company
plans to continue  development of the Oates SW Field throughout 2006,  targeting
the shallower Wolfcamp,  Atoka and Woodford formations in addition to the deeper
Devonian.

In the multi-well  re-completion program elsewhere in the Delaware Basin of West
Texas, the Company is currently recovering  completion fluid from two wells that
were fracture  stimulated in the Atoka formation  while a third well,  which was
re-completed to the Wolfcamp  formation,  is flowing  significant amounts of oil
and gas. The Company  plans to  re-complete  or fracture  stimulate  four to six
additional wells in this program during 2006.

In the Sharon Ridge Field located in Scurry County, Texas, the Company has begun
drilling a shallow well targeting the Clear Fork formation at a depth of 3,500'.
The Company plans to drill one additional in-fill well in this field in 2006.

In Brooks Draw, Wyoming,  production testing continues on the four wells drilled
in late 2005.  Since the beginning of 2006,  one  additional  formation has been
perforated and awaits fracture  stimulation and a previously completed formation
has been  re-stimulated.  The  Company  plans to  complete  additional  zones as
service equipment becomes available.  As previously  announced,  once all of the
formations are completed and tested individually, they will be commingled and an
ultimate  sustained  rate of  production  can be obtained.  The Company plans to
drill several more wells in Wyoming during the second half of 2006.

The Company's current net production is approximately 22 MMcfepd.

"Operationally,  we are very optimistic as the multi-well  re-completion program
in West Texas has begun to bear some results.  Given that we have a workover rig
under contract,  this program should provide us with steady production growth at
an  attractive   finding  cost.  Initial  results  in  Wyoming  continue  to  be
encouraging even though we have been hampered by adverse weather  conditions and
limited by the availability of service equipment.  As we have stated before, rig
(and other service  equipment)  availability  will largely dictate where we will
focus our drilling efforts in 2006. Nonetheless,  we have numerous projects that
can be completed utilizing the workover rigs we currently have under contract or
our own workover rigs," 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 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.
