Ghana's Oil Find - Reserves Are More Promising
Another successful appraisal has been made of an oil well in the West Cape Three Points Block, offshore Ghana.
The Mahogany-4 well, which is the eastern-most appraisal of the Jubilee field, encountered more than 140 net feet of predominantely oil pay in high-quality, stacked reservoir sands. The well is located approximately five miles east of the original Mahogany-1 discovery well and about 2.5 miles northeast of the Mahogany-3 appraisal and Mahogany Deep discovery well.
'The encouraging results of the Mahogany-4 appraisal well build upon our successful delineation programme that continues to extend the potentially productive area of the Jubilee field beyond the existing unit boundaries,' said Bob Daniels, Anadarko Senior Vice President, Worldwide Exploration. '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.'
Reservoir fluid samples recovered from the well indicated an oil gravity of approximately 35 degrees API. 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.
Once the rig completes operations at Mahogany-4, it will move to drill a development well in the Jubilee field, followed by appraisal wells to delineate the nearby Odum and Tweneboa discoveries.
The partnership also recently spud 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 per cent interest in the West Cape Three Points Block. Kosmos Energy is the block operator and also holds a 30.875 per cent interest.
Other partners include Tullow (22.896 per cent), Sabre (1.854 per cent), The E.O. Group, a Ghanaian oil and gas company, (3.5 per cent) and the Ghana National Petroleum Corporation (10 per cent carried interest).
In Cote d’Ivoire, the company announced that the South Grand Lahou exploration well in block CI-105 offshore Cote d’Ivoire reached the targeted objective and found it to be water bearing. The well was drilled to a total depth of approximately 14,900 feet in about 6,100 feet of water.
'To date, we have enjoyed tremendous success in our West African Cretaceous programme,' said Daniels. 'The South Grand Lahou exploration well, which was drilled in less than 20 days, did not encounter hydrocarbons, but it does provide us with an important calibration point within the trend.
We plan to incorporate the data into our models as we evaluate our 2010 programme that will continue to mature the more than 30 additional identified prospects and leads in the trend.'
