Abstract

This study improved the conclusions provided by Obibuike et al. (2022) by critically examining the Pressure-Volume-Temperature (PVT) properties, well placement, establishing hydrocarbon pore volume injected (HDPVI) as the basis of comparison (instead of time), and conducting the flood simulations at more reasonable pressures. Furthermore, a sensitivity study of dip was performed on the given reservoir which concluded that EOR benefits from gas versus water injection are highly sensitive to this variable, such that a generalized conclusion of water versus gas cannot be made. It also identifies additional variables that may also affect the relative results for areas of further study.
