+++ Geology
- The trapping mechanism is a south-plunging anticlinal horst surrounded on all sides by faults that are sealed vertically by fine-grained upper Cretaceous rocks and laterally by Tertiary shale. Numerous small faults occur within the structure.
- A gas cap (up to 1,100 ft thick in the northernpart of the reservoir) overlies a 480-ft-thick oil column.
- The Pinda formation in the field consists of a sequence of interbedded carbonate and clastic rocks that is more than 3,500 ft thick in the discovery well
