Tullow Oil with Successful Ebony-1 exploration well offshore Ghana
Tullow Oil plc (“Tullow”) announces that the Ebony-1 exploration well, located in the Shallow Water Tano licence offshore Ghana, has intersected two hydrocarbon bearing intervals in Late Cretaceous turbidite sands. Ebony-1 spudded on 22 October and reached a total depth of 2,640 metres. The well lies in the south-west part of the Shallow Water Tano block in 86 metres of water and is the second commitment well in this licence.
Successful logging and sampling operations have confirmed a four metre oil bearing interval at 2,053 metres and a two metre high-pressure gas-condensate interval at 2,570 metres.
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 licence. Other possible interpretations for the high-pressure cannot however be excluded at this stage, and this is subject to ongoing evaluation.
Tullow (31.5%) operates the Shallow Water Tano licence on behalf of partners Interoil (31.5%), Al Thani (22.5%), Sabre Oil and Gas (4.5% carried) and GNPC (10% carried).
