NIPER is conducting a DOE-industry sponsored project to determine the feasibility of applying surfactant-enhanced alkaline flooding technology. This report focuses on research conducted between October 1993 and September 1994. During this time period, a second field tracer survey was conducted, prior field and laboratory data were reevaluated, additional laboratory research was conducted with field cores (e.g., experiments were conducted to determine if parameters such as transient IFT behavior, core wettability, and unspecified oil properties would affect oil recovery from Hepler field cores), and the project participants decided not to implement field injection of a chemical system designed for a field test on the Elmer C lease of Hepler oil field located in Southeast Kansas. For detailed information on other aspects of the feasibility study and on specific laboratory procedures, the reader is directed to the several reports and publications that resulted from the study.
