  HOUSTON, TX, Mar 19 (Marketwire) -- 
Anadarko Petroleum Corporation (NYSE: APC) today announced its
Shenandoah-2 well in the deepwater Gulf of Mexico encountered more than
1,000 net feet of oil pay in multiple high-quality Lower Tertiary-aged

    "The successful Shenandoah-2 well marks one of Anadarko's largest oil
discoveries in the Gulf of Mexico, with more than 1,000 net feet of oil
pay and reservoir rock and fluid properties of much higher quality than
previously encountered by industry in Lower Tertiary discoveries," said
Bob Daniels, Anadarko Sr. Vice President Deepwater and International
Exploration. "With ownership in the successful Shenandoah wells, the
adjacent Yucatan prospect, and the very encouraging results from the
nearby Coronado well, Anadarko is strategically positioned in the
Shenandoah Basin, which has the potential to become one of the most
prolific new areas in the deepwater Gulf of Mexico."

    The Shenandoah-2 well, located in Walker Ridge block 51, was drilled to a
total depth of 31,405 feet in approximately 5,800 feet of water, more
than 1 mile southwest and approximately 1,700 feet structurally down-dip
from the Shenandoah-1 discovery. Similar to the initial Shenandoah
discovery well, log and pressure data from the Shenandoah-2 well indicate
excellent-quality reservoir and fluid properties. The well was drilled to
test the down-dip extent of the accumulation, and the targeted sands were
full to base with no oil-water contact.

    "We are incorporating the information obtained from Shenandoah-2 into our
planning and anticipate further appraisal drilling to advance this
potentially giant project," Daniels added.

    Anadarko is the operator of the Shenandoah-2 well and the previously
announced Shenandoah-1 discovery well, located in Walker Ridge block 52,
with a 30-percent working interest. Other co-owners in Shenandoah are
ConocoPhillips (NYSE: COP) with a 30-percent working interest, Cobalt
International Energy L.P. (NYSE: CIE) with a 20-percent working interest,
Venari Resources LLC with a 10-percent working interest and Marathon Oil
Company (NYSE: MRO) with a 10-percent working interest. 

    Additionally, in the Shenandoah Basin, Anadarko has a 15-percent working
interest in both the Coronado well, located in Walker Ridge block 98, and
the Yucatan prospect, located in Walker Ridge block 95.
