Tullow Oil PLC said its Wawa-1 exploratory well on the Deepwater Tano license offshore Ghana has intersected oil and gas-condensate in a Turonian turbidite channel system.
Wawa is the first of three remaining exploratory wells to be drilled in the second half of 2012 to close out the exploration phase of the license, Tullow noted.
It found light oil and gas condensate, trapped separately from the Tweneboa-Enyenra-Ntomme fields “and demonstrates once again that liquid rich hydrocarbons are pervasive in this prospective license. We look forward to the drilling of Okure and Sapele in the second half of 2012,” the company said.
Wawa-1 encountered 20 m of gas-condensate pay and 13 m of oil pay in turbidite sands. Samples show the oil to be good quality of 38-44° gravity. Wawa, which will be suspended for possible future use, is 10 km north of the Enyenra-3A well, testing the previously undrilled, updip area of the license.
The Atwood Hunter semi submersible rig drilled Wawa-1 to 3,322 m in 587 m of water.
Tullow operates the license with 49.95% interest. Kosmos Energy Co. and Anadarko Petroleum Corp. have 18% each, Sabre Oil & Gas has 4.05%, and Ghana National Petroleum Corp. has a 10% carried interest.
