Business Wire

SAN ANTONIO -- March 15, 2013

Abraxas Petroleum Corporation (NASDAQ:AXAS) is pleased to provide the
following operational and A&D update.

Eagle Ford Shale

In McMullen County, the Corvette C 1H averaged 867 boepd (808 barrels of oil
per day, 355 mcf of natural gas per day) on a 22/64” choke over its first 30
days of production. The Corvette C 1H continues to flow to sales at a rate of
586 boepd (547 barrels of oil per day, 233 mcf of natural gas per day) on a
22/64” choke. The Gran Torino A 1H was recently completed with a 19 stage
completion and is currently flowing to sales at rates above the Company’s type
curve. Abraxas successfully completed the Mustang 3H with an 18 stage fracture
stimulation with flowback expected to commence imminently. The Company
recently drilled Mustang 2H to a total depth of 15,021 feet with an
anticipated fracture stimulation date in April. Abraxas owns a 25% working
interest in the Corvette C 1H and an 18.75% working interest in the Gran
Torino A 1H, Mustang 3H and Mustang 2H.

Williston Basin

Drilling continues on the Company’s Lillibridge East PAD with intermediate
casing set on the 1H, 2H, 3H and 4H. The Company recently drilled and cased
the lateral on the 4H with a 50 foot flare encountered while drilling. The rig
is now preparing to spud the lateral of the 3H, which will be followed by the
2H and 1H. Abraxas owns a working interest of approximately 34% in the
Lillibridge East PAD. As previously announced, the Ravin 2H and Ravin 3H were
recently completed with the Ravin 2H performing in line and the Ravin 3H
outperforming the Company’s type curve. Abraxas owns a 49% working interest in
both the Ravin 2H and 3H.

Permian Basin

The Company recently drilled and cased two shallow Yates wells, the Wilkes #1
and Wilkes #2, in Ward County, Texas. Early logs are encouraging, and Abraxas
expects to complete the wells in April. Abraxas owns a 100% working interest
in both wells.

A&D Update

Abraxas recently sold a portion of the Company’s properties in Oklahoma and
Louisiana as well as scattered royalty interests in North Dakota and Montana
at the March 2013 Oil and Gas Clearinghouse Auction for gross proceeds of
approximately $2.9 million. Combined, the properties sold produce 27.5 barrels
of oil per day and 220.7 mcf of natural gas per day. The remainder of the
Company’s Oklahoma properties and additional North Dakota royalty interests
are scheduled to be offered at the May 2013 Oil and Gas Clearinghouse Auction.
The marketing process led by E-Spectrum Advisors for Abraxas’ non-operated
Bakken and Three Forks assets is under way.

Bob Watson, President and CEO of Abraxas, commented, “Strong production
volumes in February and early March, along with incremental well performance
and the efficiency gains in the Eagle Ford, give us confidence in our 2013
guidance of 4,900-5,200 boepd on a $70 million CAPEX budget. With the Corvette
C 1H, Abraxas completed its fourth high rate oil well in the Eagle Ford
significantly above expectations. The Ravin 2H and Ravin 3H are flowing to
sales at encouraging rates after we experienced significant completion issues
and delays due to a third party. Furthermore, we continue to make progress in
our efforts to refocus our portfolio and delever our balance sheet, with the
non-op Bakken sale process starting in earnest as well as the recent sale of
several non-core properties in Oklahoma, Louisiana and scattered royalty
interests in North Dakota and Montana. We look forward to updating the market
as we continue to execute against our strategic priorities and continue to
enhance shareholder value.”
