Anadarko has finalized plans for its previously announced 2011 drilling campaign in the Liberian Basin. To carry out this program,
Anadarko intends to mobilize the Discoverer Spirit drillship from the Gulf of Mexico to West Africa after it finishes completion activities
on the third Caesar/Tonga well. Subject to the finalization of a contract amendment with the rig owner, the Discoverer Spirit is expected to begin drilling in West Africa during the third quarter.
As part of this program, Anadarko plans to drill its first Mercury appraisal well, located approximately seven miles west of the Mercury
discovery well offshore Sierra Leone in Block SL-07B-10. In addition, the company plans to drill the Jupiter exploration prospect on the
same block later in the year. Anadarko operates Block SL-07B-10 with a 65-percent working interest.
Offshore Liberia, the company plans to drill the Montserrado exploration well on Block 15, which is operated by Anadarko with a
57.5-percent working interest. Further to the east, on Block 10, Anadarko recently completed the acquisition of a 2,400-square-kilometer 3D seismic survey. Processing of the survey is expected to take approximately six to nine months, and with the
acquisition of this data, Anadarko will have 3D seismic information covering virtually all of its acreage in the Liberian Basin.
"Mobilizing the Discoverer Spirit to West Africa ensures our ability to deliver upon our exploration and appraisal programs in a timely
fashion in an area that offers tremendous potential with more than 30 identified Jubilee-like prospects on our acreage," said Al Walker,
Anadarko President and Chief Operating Officer. "We plan to keep the ENSCO 8500 rig in the Gulf of Mexico to conduct an extended well test at Lucius and, once we receive drilling permits, we are confident that we will be able to utilize the ENSCO 8500 and contract a
deepwater rig of opportunity to resume our development and exploration programs in the Gulf."
