Petrophysical Evaluation and Depositional Environments of Reservoir Sands in an Oil Producing Field, Onshore Niger Delta, Nigeria

Optimal hydrocarbon recovery depends strongly on predicting the reservoir quality and drive mechanism, this could be achieved by petrophysical analysis. This research evaluated properties of sands in an Oil producing Field, onshore Niger delta, Nigeria using techniques. Results from Petrophysical evaluation, showed that average porosity values reservoirs ranged between 0.15 0.24 while water saturation for three 19% to 44%. Reservoir D_3000 has largest accumulation about 952 MMSTB D_1000 gave least 727MMSTB. The environment deposition was interpreted gamma-ray log motif. shows a blocky gamma ray motif suggests steady energy, which can likely channel deposits. D_2000 obvious funnel shape it coarsening upward attribute, as shore face environment. is deepest thickest sands, displayed bar deposits sands. study reveals Channel Sands, Bars Shore are good sites exploration production hydrocarbon.
