Pitts, M J

The study will investigate two major areas concerning co-injecting an interfacial tension reduction agent(s) and a mobility control agent. The first will consist of defining the mechanisms of interaction of an alkaline agent, a surfactant, and a polymer on a fluid-fluid and a fluid-rock basis. The second is the improvement of the economics of the combined technology. This report examines the effect of different alkaline agents, surfactants, and combinations of surfactant and alkaline agents on the reduction of interfacial tension between a fluvial. deltaic crude oil and the aqueous solution. In addition, the effect of alkali and surfactant addition to polymer solution viscosity are evaluated. Finally, the effect of increasing temperature on the interfacial tension characteristics and solution viscosity characteristics are discussed.
