Abstract
Shale studies are essential for the optimization of the reservoir performance as its presence can significantly reduce the oil reserves. Contingent on the degree of communication, reservoir dynamics can vary considerably, leading to several key issues including well completion and perforation strategy and enhanced recovery program. The principal aim of this study is to investigate the optimum location to inject water in waterflooding scheme or gas for an immiscible water-alternating gas (WAG) scheme in the presence of lateral extension of continuous shale in the reservoir. A sensitivity analysis of the optimum injection place is conducted with respect to various locations of the shale orientation. The objectives of this project include studying the trend of the vertical distribution of lateral shale and its effect on the recovery factor, conducting a comparative study between the performance of two flooding techniques; waterflooding and immiscible water-alternating gas (WAG) injection and to further optimize the resulting best cases of injection-perforated intervals. The simulation work of this project was carried out using Schlumberger Eclipse 100 simulator.
