Abstract: Suites of wire-line logs from seven (7) wells were integrated with 3D seismic data in order to characterize reservoir D_7 and estimate its hydrocarbon volumes. Detailed seismic interpretation was carried out to determine geologic structures. Seismic-to-well tie was done using previously generated synthetic seismogram, and this was used to pick the reservoir horizons; time and depth structural maps were subsequently generated. Geostatistical models were built using the Sequential Indicator Simulation and Sequential Gaussian Simulation which resulted in improved distribution of reservoir properties within the geologic cells. Statistical analysis of Porosity, Water saturation and Net-to-gross models for the reservoir revealed porosity values ranging from 18% to 27%, average water saturation of 45% and mean Net-to-gross value of 70%. Furthermore, the structural model showed a fault assisted closure. Finally, volumetric estimation revealed a STOIIP of 84Mstb. The results of this study has shown good hydrocarbon potential of reservoir D_7.
