Wawa-1 exploration well finds oil and gas-condensate

Tullow Oil plc (Tullow) announces that the Wawa-1 exploration well in the Deepwater Tano licence offshore Ghana has intersected oil and gas-condensate in a Turonian turbidite channel system.

Wawa-1 encountered 20 metres of gas-condensate pay and 13 metres of oil pay in turbidite sands. Samples show the oil to be good quality between 38 and 44 degrees API. The well was drilled 10 kilometres north of the Enyenra-3A well, testing the previously undrilled, updip portion of the licence. Pressure data shows that it is a separate accumulation from the TEN fields.

The well will now be suspended for possible future use in appraisal and development operations.

The Atwood Hunter semi submersible rig drilled the Wawa-1 well to a final depth of 3,322 metres in water depths of 587 metres.

Tullow (49.95%) operates the Deepwater Tano licence and is partnered by Kosmos Energy (18.00%), Anadarko Petroleum (18.00%), Sabre (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).

Commenting today, Angus McCoss, Exploration Director, said:

"Wawa-1 was the first of three important remaining exploration wells to be drilled in the second half of 2012, to close out the exploration phase of the Deepwater Tano Licence. It found light oil and gas condensate, trapped separately from TEN and demonstrates once again that liquid rich hydrocarbons are pervasive in this prospective licence. We look forward to the drilling of Okure and Sapele in the second half of 2012."
