The majority of the formation damage models were developed for single-phase fluid systems. This assumption is valid only for very specific cases such as the production of particles with single-phase flow of either oil or water, and for special core tests. Nevertheless, it is instructive to understand these models before looking into the multiphase effects. Therefore, the various processes involving single-phase formation damage are discussed and the selected models available are presented along with some modifications and critical evaluation as to their practical applicability and limitations. The methodology for determination of the model parameters is presented. The parameters that can be measured directly are identified. The rest of the parameters are determined by means of a history matching technique. The applications of the models and the parameter-estimation method are demonstrated using several examples.
An evaluation and comparison of the outstanding selected models bearing direct relevance to formation damage prediction for petroleum reservoirs...
