A Chemical Flood Predictive Model (CFPM) for micellar-polymer processes is developed. It consists of a technical screen, oil rate and recovery algorithms and an economics model. The CFPM is based upon an analysis of all available laboratory and field data (circa 1980) which leads to three efficiencies: E/sub D/, the surfactant pore displacement efficiency; E/sub V/, the efficiency of moving the surfactant from the injector to the pore space; and E/sub MB/, the efficiency of moving mobilized oil from that pore space to the producer. Oil timing is estimated from oil-water fractions flow theory. The CFPM is applicable to waterflooded sandstone reservoirs, and the effects of heterogeneity, crossflow between layers, and surfactant adsorption are included. The CFPM can be used to designate the better micellar-polymer prospects in Mid-Continent and California regions and can be used to aid in the design and development of micellar-polymer floods. 38 references, 50 figures, 15 tables.
