Geological Behavior (GBR)

The purpose of this study was to use petrophysical parameters to estimate the Total Oil in Place (TOIP) and the area extent of hydrocarbon accumulations in reservoirs from an oilfield in the Niger Delta basin. During the project, each hydrocarbon bearing zone identified from two oilfield wells was measured for porosity, permeability, water saturation, reservoir thickness, and shale volume. Using the average results of petrophysical characteristics, twelve reservoir zones of interest (sand bodies) were identified, correlated throughout the field, and ranked. The area extents of the accumulations were then calculated using volumetric equations. It was determined that the recoverable oil reserves for Well-001 and Well-002 were 148.45MMBB and 145.91MMBB, respectively. The accumulation’s respective area extents in W-001 and W-002 were determined to be 0.974 acres and 2.92 acres. According to the obtained results, we assert that there is oil and gas that may be exploited in the field under study. We also assert that W-001 may be more productive than W-002 in terms of oil accumulation, while W-002 has greater gas accumulations than W-001. The study’s outcome is quite helpful since it gives field asset managers valuable insights they need to create their oilfield exploitation and recovery plans.
