Ophir Energy said it has signed a contract with AP Moller-Maersk for the use of an ultra deepwater semi-submersible drilling rig for the Kora prospect in Senegal.

The Maersk Deliverer rig will arrive on location in 2011 to drill the Kora prospect, which has an Upper Cretaceous primary reservoir objective located in 2,600m of water.

The rig was contracted on behalf of the AGC Profond joint venture in the Senegal Guinea Bissau Common Zone that Ophir operates in partnership with L’Entreprise and Rocksource ASA.

The rig will undertake several operations in the West Africa region on behalf of other clients before drilling the AGC Profond well, Ophir said.

AGC, a joint commission with sovereign status set up by the governments of Guinea-Bissau and Senegal, consists of the deepwater portions of two blocks covering an area of 9,838km² in water depths of up to 3,500m.

Ophir Energy has an 83% operating interest in the AGC Profound joint venture while L’Entreprise owns 12% and the rest is held by Rocksource ASA.
