MID CRETACEOUS SUBSURFACE CARBONATE DEPOSIT AND RESERVOIR DEVELOPMENT OF THE MFAMOSING LIMESTONE CALABAR FLANK

This research analyzed the reservoir quality of Mfamosing Limestone with a view to classifying it as potential rock within Calabar Flank. Materials used in this are processed seismic data acquired around flank and well logs three wells (A, B, C) drilled at different periods study area, core mud log data. The procedure involved prospect identification mapping, structural stratigraphic analysis, classification carbonate area. results were classified using hydrocarbon storage capacity deliverability potential. Wells A B was 0.8km apart C 4.7km from which encountered indicating Well had shallower sandstone lenses. lens tested for flowed briefly stopped. planned reference amongst other parameters evaluate Limestone. found completely dry. Two conventional coring runs depths 10,490ft-10,552.5ft 10,552.5ft-10,614ft indicated that cored intervals light grey, moderate very hard, fossil rich limestone no direct fluorescence. analysis suggest is dry highly indurated evidence physical porosity. penetrated by all though massive has typical rock. therefore suggests Mid Cretaceous subsurface more mineral deposit than reservoir.
