LONDON -- The Ebony-1 exploration well, located offshore Ghana, has intersected two hydrocarbon-bearing intervals in late Cretaceous turbidite sands, according to Tullow Oil.
The well reached a total depth of 2,640 m (8,661 ft). The well lies in the southwest part of the shallow water Tano block in 86 m (282 ft) of water and is Tullow's second commitment well in this license.
Successful logging and sampling operations have confirmed a 4 m (13-ft) oil bearing interval at 2,053 m (6,736 ft) and a 2 m (6.6 ft) high-pressure gas-condensate interval at 2,570 m (8,432 ft), the company reports.
According to Tullow, log and sample data from the high-pressure gas-condensate sands and a regional seismic interpretation, indicate there may be a connection between these pinched-out sands and the material down-dip Tweneboa oil prospect, which lies mainly in the deepwater Tano license. The company believes other possible interpretations for the high-pressure cannot be excluded at this stage, and data is subject to ongoing evaluation.
