Hydrocarbon reservoir characterization of “Otan-Ile” field, Niger Delta

Abstract Otan-Ile field, located in the transition zone Niger Delta, is characterized by complex structural deformation and faulting which lead to high uncertainties of reservoir properties. These greatly affect exploration development thus require proper characterization. Reservoir characterization requires integration different data such as seismic well log data, are used develop model. Therefore, objective this study characterize sand bodies across field evaluate petrophysical parameters using 3-dimension from four wells. sands were delineated combination resistivity gamma ray logs. The estimation properties, gross thickness, net volume shale, porosity, water saturation hydrocarbon saturation, done standard equations. Two horizons ( T U ) major minor faults mapped ‘Otan-Ile’ field. results show that average permeability 28.19 m, 15%, 37%, 71% 26,740.24 md respectively. F 1 5 dipping northeastern northwestern direction identified. closures can accommodate Amplitude maps superimposed on depth-structure map also validate potential it. This shows 3D with attribute a good tool for
