A steam foam solution and a steam foam encapsulated in a polymer gel are being introduced in four steam injection patterns in the North Kern Front Field near Bakersfield, California. The ability of the ancillary materials to improve recovery will be determined through injection profiles, chemical tracer surveys, casing vent gas analyses, core and log data and residual oil saturation data, as well as through temperature and production monitoring. It has been shown that in-situ steam foams can be used to alter the steam injection profiles to prevent excessive steam channeling. Results after injection of ancillary materials for approximately 18 months indicate that improvements in both the areal and vertical sweep efficiencies have been found in the four treated patterns when compared to the untreated control patterns. Several techniques are still under evaluation to determine the exact amount of incremental oil produced. Discussion of production response will be limited to two of the four treated patterns, Witmer B2-3 and Witmer B2-5. A comparison of these two patterns to the Witmer control pattern, Witmer A2-7, indicates approximately 52 B/D (8 mv/d) of incremental oil is being produced as a result of the weekly chemical treatments.
