Tweneboa appraisal well confirms potential

By OGJ editors
HOUSTON, Jan. 10
-- The Tweneboa-3 appraisal well on the Deepwater Tano block off Ghana encountered gas-condensate and confirmed the Greater Tweneboa area’s resource base potential.

The group led by Tullow Oil PLC plans to evaluate development options for Tweneboa and Enyenra, formerly Owo, fields.

Tweneboa-3 well was drilled with two deviated boreholes. The first leg was drilled to calibrate the potential of an area that had a weak seismic response. This leg encountered 29 ft of gas-condensate pay, in line with expected results.

The well was then sidetracked 1,808 ft) west to test an area of strong seismic response. This leg encountered a gross vertical reservoir interval of 214 ft and penetrated 112 ft of net gas-condensate pay in high-quality stacked reservoir sandstones in two zones.

Tweneboa-3 well is 7.5 miles southeast of the Tweneboa-1 discovery well. The Deepwater Millennium dynamically positioned drillship drilled Tweneboa-3 to a total depth of 12,816 ft in 5,253 ft of water. The well will be suspended for potential future use in field development.

The drillship will remain on the block to drill the top-hole section of the Tweneboa-4 appraisal well and suspend it. Then the drillship will drill the Enyenra-2A well, which will appraise the Owo-1 discovery well.

Deepwater Tano block interests are Tullow Oil 49.95%, Anadarko Petroleum Corp. and Kosmos Energy Inc. 18% each, Sabre Oil & Gas Holdings Ltd. 4.05%, and Ghana National Petroleum Corp. has a 10% carried interest.
