LONDON – Operator Tullow Oil has spudded well GM-ES-1 on the Zaedyus prospect in the Guyane Maritime Permit, says partner Northern Petroleum. The well is offshore of Guyane about 50 km (~30 mi) from the Brazilian border.
The ENSCO 8530 is drilling to a planned 6,500 m (21,325 ft) subsea to test an undrilled Late Cretaceous fan system.
Tullow has stated that the Zaedyus prospect has an estimated P10 prospective resource of 700 million barrels and is geologically analogous to its Jubilee field, located off the coast of Ghana, Africa.
Tullow holds 27.5%, Northern has 1.25%, Shell E&P France SAS 45%, Total E&P Guyane Francaise SAS also 25%, and Wessex Exploration at 1.25%.
