Abstract This study analyzes the geological characteristics and hydrocarbon potential of the "BOL" oil field, located in an area with typical Agbada formation sedimentation. Well logs and seismic data were utilized to evaluate the stratigraphy and structural styles of the field. The panel was composed of four wells (TM-02, TM-01, TM-05, and TM-04) oriented in a northeast to southwest direction, with an alteration of sand and shale layers typical of the Agbada Formation. Twelve sands were mapped across the four wells, with two prospective reservoir sands delineated in the depth interval of 8500 ft and 11200 ft. The reservoir sands were found to contain mostly oil and formation water. The study area was found to be extensively deformed by extensional normal faults and mobilization of deep overpressured shale, resulting in a chaotic reflector geometry within the lower Agbada formation. The results indicate that the field is structurally controlled by sets of antithetic faults trending northwest-southeast and dipping southwest, with two synthetic faults identified. Depth structural maps were generated to evaluate the probable structures responsible for the accumulation of hydrocarbons in the study location. The maps showed that the existing wells were located close to the major fault F1, which is a fault assisted closure with high prospectivity. The facies lateral distribution using Root mean square (RMS) amplitude attributes showed that sand lithologies were distributed across the study area, with patches of sand units occurring in the northwestern and southeastern area of the map.
