Anadarko Petroleum Corporation (APC) today drilled another appraisal well – Mahogany-4 well – in the West Cape Three Points Block offshore Ghana, in the eastern part of Jubilee field. The well witnessed more than 140 net feet of predominately oil pay in high-quality, stacked reservoir sands.
The Mahogany-4 appraisal well is a part of the company’s delineation program that extends the potentially productive area of the Jubilee field beyond the existing unit boundaries. The well intersected the main Jubilee reservoir and also encountered new deeper oil sands that the partnership plans to evaluate through future exploration and drilling activity.
The well was drilled to a total depth of about 12,000 feet in approximately 3,540 feet of water by the “Atwood Hunter” semi-submersible drilling rig. Following the completion of the Mahogany-4 well, the rig will drill a development well in the Jubilee field. Following that it will drill appraisal wells to delineate the nearby Odum and Tweneboa discoveries.
The partnership has also recently started the Mahogany Deep-2 well in the West Cape Three Points Block. This well is an appraisal of the Mahogany Deep discovery announced earlier in 2009, as well as a test of the Jubilee field’s southern extent. Anadarko holds a 30.875% interest in the West Cape Three Points Block.
Kosmos Energy is the block operator and also holds a 30.875% interest. Other partners include Tullow (22.896%), Sabre (1.854%), the E.O. Group (3.5%), and Ghana National Petroleum Corporation (10% carried interest). In addition, the company announced that the South Grand Lahou exploration well in block CI-105 offshore Cote d’Ivoire reached the targeted objective.
The well was drilled to a total depth of approximately 14,900 feet in about 6,100 feet of water. The company said that the South Grand Lahou exploration well did not encounter hydrocarbons, though it provided Anadarko with an important calibration point within the trend.
Anadarko operates South Grand Lahou with a 50% working interest. Anadarko also highlighted plans to mobilize the Belford Dolphin drillship to Mozambique to begin its drilling program obligation with the Windjammer prospect. Anadarko holds a 42% working interest and is the operator. Windjammer will be the first deepwater exploration well to be drilled offshore Mozambique.
