Tullow said the Wawa 1 well has encountered 20 metres (65.6 feet) of gas-condensate and a further 13 metres (42.6 ft) of oil in turbidite sands, at a location 10 kilometres (6.2 miles) from the earlier Enyenra 3A discovery.
“Samples show the oil to be good quality between 38 and 44 degrees API,” Tullow said, after drilling the well in the Deepwater Tano licence area offshore Ghana with the Atwood Hunter semi-submersible operating a water depth of 587 metres (1,925 feet).
Pressure data from the well suggests it is a separate accumulation from the TENS fields which are already being considered for development by Tullow and its Deepwater Tano licence partners.
“The well will now be suspended for possible future use in appraisal and development operations,” said the company.
"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,” Commented Tullow exploration director Angus McCoss.
He went on: “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."
Tullow operates the Deepwater Tano licence Tullow with 49.95%. Its partners are Kosmos Energy and Anadarko Petroleum , which each hold 18.00%), Sabre with 4.05% and the Ghana National Petroleum Corporation (GNPC) which holds a 10% carried interest.
