Evaluation of Hydrocarbon Reservoir in the “SIMA” Field of Niger Delta Nigeria from Interpretation of 3D Seismic and Petrophysical Log Data

3D seismic and petrophysical log data interpretation of reservoir sands in “SIMA” Field, onshore Niger Delta has been undertaken this study to ascertain the characteristics terms favourable structural parameters suitable for hydrocarbon accumulation entrapment field. Horizon fault were carried out subsurface delineation. In all, seven faults (five normal two listric faults) mapped section. These major structure building corresponding growth antithetic area within well control. The trending northwest-southeast northeast-southwest on high section act as good trapping mechanisms accumulations reservoir. From manual auto-tracking methods applied, several horizons identified mapped. is characterized by amplitude with moderate-to-good continuity reflections appearing parallel sub-parallel, mostly disturbed some truncations which are more related than lithologic heterogeneity. southwestern part is, however, low-to-high or variable poor-to-low continuity. Normal linked roll-over anticlines identified. Some observed due combination these acts traps Reservoir qualities, having average NTG, porosity, permeability water saturation 5 m, 0.20423, 1128.219 kD 0.458 respectively.
