UK-based oil explorer Tullow Oil and U.S. producer Anadarko Petroleum made new discoveries around their Jubilee field in Ghana, Tullow said on Thursday.
Tullow Oil said its Mahogany-3 well had made a new discovery beneath its Jubilee field and that the drilling also showed the field extended far further to the southeast than it thought.
The company said in a statement on Thursday that the results raised its expectations for the field, although it did not specify new reserves estimates.
