Abstract:

Sedimentological, Biostratigraphic, and Wireline techniques were applied to AF-1 Well for well based characterisation. Hundred (100) ditch cutting samples were analysed and a lithologic section was produced based on the sedimentological analysis. AF-1 Well has a total thickness of 6335 ft ranging from depths of 5525ft – 11860ft. From 5525ft – 7175ft, continental sands were encountered. From 7235ft – 11860ft, there was intercalation of sand and shale lithologies.

Three Maximum Flooding Surfaces (MFSs) were picked and dated as P784 (10.4Ma), P770 (11.5Ma) and P750 (12.8Ma). Two Sequence Boundaries (SBs) were picked, which were at P784 (10.6Ma) and P750 (12.1Ma).
