A NUMERICAL COMPARATIVE STUDY OF VARIOUS FLOODING TECHNIQUES IN HYDROCARBON RESERVOIRS

摘要

This paper investigates the efficiency and performance of several of the flooding techniques popular in secondary and enhanced oil recovery. These processes include water flooding, immiscible and miscible gas flooding, and several forms of water-alternating-gas (WAG) injection. The study is carried out numerically on a typical one-dimensional domain using an advanced high-resolution central scheme. Some performance indices such as oil cut drop, breakthrough time, and sweep efficiency were employed to evaluate the appropriateness of each injection strategy.
