Description
Summary:By using drilling data and geophysical wireline logs of twenty-three wells in the Bornus Basin, the overall distribution of stratigraphic formations (Kerri-Kerri, Gombe, Fika, Gongila and Bima) in the basin have been simulated with software of Excel, Petrel and Surfer etc. Three major sags, labeled A, C and D and a structural high B, have been identified. Sag A is located in the northeast, while sags C and D are located in the southeast and southwest of the basin, respectively, structural high B separates sag A from sag C. All the existing stratigraphic formations (Kerri-Kerri, Gombe, Fika, Gongila and Bima) are widespread in the basin, but with variation in thickness. Drilling data of three deep wells (Kadaru – 1, Herwa – 1 and Kinasar – 1) showed that only the upper part of Bima Formation (middle to coarse grained arkose) have been penetrated, while the lower part of Bima Formation is not drilled yet, therefore, it is suggested that the deep formations in the sags be drilled to find their hydrocarbon potential.
