Integration of Well Logs and Seismic Data for Hydrocarbon Volumetric Analysis in DOne Field of the Niger Delta Region, Nigeria

The study was carried out on an onshore niger delta field using seven wells with the objectives of identifying possible reservoir units with potential to contain oil or gas using well logs and seismic data sets. petrophysical properties analysis revealed two hydrocarbon bearing reservoirs ranging from 5000 ft – 8000 ft, with volume of shale (vsh) ranging from 4.3% - 43.9%. the total porosity ranged from 25.9% - 34.7%, while effective porosity ranged from 17.7% - 33.2%, indicating good porosities for the reservoirs. net-to-gross ranged from 0.720 – 0.980 with water saturation ranging from 19.87% - 29.07%, while hydrocarbon saturation ranged from 70.93% - 78.86% of gas in the reservoirs. for the volumetric analysis of the two reservoirs modelled, a stoiip ranging from 614mmstb – 1054mmstb was obtained, while the recoverable oil was estimated between 215-369mmstb. we can infer that the two reservoirs mapped, correlated and modelled across the seven wells has a respectable hc potential.
