The well encountered 26 net ft (7.9 m) of oil pay in good-quality upper Oligocene sands below the Alen field. It was drilled in 1,900 ft (579 m) of water to a depth of 11,500 ft (3,505 m).
Noble estimates reserves in the range 35-100 MMboe of which 80% are liquids.
Recent appraisal work at Diega, a 2008 discovery, has confirmed resources of 45-110 MMboe of which 60% are liquids. Noble expects to develop both Carla and Diega through the infrastructure at either the newly producing Aseng field in block I, or at Alen which is due to come onstream in late 2013.
Offshore Cameroon, another Noble well testing the Bwabe prospect in the Tilapia block reached total depth without finding commercial hydrocarbons.
However, the company has identified a new offshore Cameroon prospect, Bouma, which could contain 95-400 MMboe, with a 35% probability of geologic success.
