Practical model for chemically induced formation damage

A phenomenological model to simulate formation damage by dissolution/precipitation, ion exchange, fines migration and clay swelling is presented. The model parameters are determined by an optimum history matching of the model predictions to laboratory core test data. The capability and validity of the model are demonstrated by comparing the model predictions with experimental data. This model can be used for diagnosis, evaluation, and simulation of reservoir formation damage during drilling, production, and chemical flooding processes.
