The interfacial activity and mobility control of a chemical flooding process are affected by the concentration of the cationic and anionic species that travel with the surfactant and polymer. In this study, equations from the literature are used to describe the environmental composition changes resulting from cation exchange which occurs as a chemical flood traverses a reservoir. This work presents examples of 2 or 3 exchanging cations (calcium, sodium, and magnesium) with and without mobilized oil present and with up to 4 fluids in a typical chemical flooding sequence (connate water, preflood, slug, and polymer drive). The results indicate how cation exchange and adsorption may be incorporated into a chemical flood design. The general theory from which the results are developed is based on the concept of coherence. This theory allows any number of exchanging cations to be present and adsorption of surfactant, polymer, or other species and their interaction with cation exchange to be included. (13 refs.)
