The Sedco Express is under a contract to expedite the timing of production tie-in from the Oyo-7 and Oyo-8 development wells. The ultra deepwater rig will also be used on up to three wells and to complete the Oyo-7 and Oyo-8 wells horizontally.
In addition, CAMAC says it is considering using the rig to drill the company’s first Miocene-target exploration well.
The company’s other rig, the drillship Energy Searcher, will continue the plugging and abandonment operations on the Oyo-5 and Oyo-6 wells.
In September, CAMAC announced that its four offshore Nigeria prospects increased the company’s unrisked P50 recoverable resources by 3 billion boe. The four prospects, Ereng, Ewo Deep, G Prospect and P Prostpect are located in OML 120 and 121.
CAMAC identified drilling locations for all four prospects, with the first exploration well planned for in 1H 2015. The wells will target the Miocene formation, which has proven to be a prolific oil production layer in deepwater Nigeria.
CAMAC Energy is operator and owns a 100% working interest in OMLs 120 and 121.
