LONDON – The drillshipMaersk Venturer started development operations for Tullow Oil offshore Ghana last month.

The first of four wells planned this year is a producer at Ntomme for the TEN development, likely to come onstream around mid-year, while the second should be a producer in the northeastern part of the Jubilee field.

Work continues to finalize the sequence of further wells to maximize production from bothJubilee and TEN, and Tullow and its partners are still considering bringing in a second rig to speed up drilling for both projects.

At Jubilee, the FPSOKwame Nkrumah was shut-down for 19 days during 1Q for first-stage work to stabilize the turret bearing and for unrelated maintenance work.

A second shutdown should follow next month to complete stabilization of the turret bearing, with a third shutdown of around one week toward year-end to rotate the FPSO to its permanent heading and install the final spread mooring anchoring system.

Gas production from TEN was used to substitute supply to Ghana National Gas Co. during the shutdown. Permanent gas sales from TEN should start in June.

Elsewhere in West Africa, Tullow is participating in a 9,000-sq km (3,475-sq mi) 3D seismic survey offshore Mauritania, due to be completed in June.
