A Multi-Purpose Formation Damage Model

Abstract

Abstract A generalized formation damage model capable of simulating a wide variety of formation damage processes encountered in the field is developed. This model was constructed to simulate the chemical, physicochemical, hydrodynamic, thermal and mechanical damage, rock-fluid and fluid-fluid interactions, and the resulting alterations in the reservoir formation. This model has been developed by combining, improving, and generalizing the features of the various modeling approaches reported in the literature for specific applications into one model. The generalized model takes advantage of the fact that the majority of the models has a common ground in the formulation with some variations in the details specific to certain formation damage processes.
