Abstract
Abstract Texaco converted 275 steam displacement patterns to hot waterflood pilots in the Kern River Field. This test program was designed to evaluate hot water injection as a viable recovery mechanism in a post steamflood reservoir. Response to hot water injection was typified by a decline in oil production and a corresponding increase in water production. Investigation into the reservoir rock and fluid properties indicated that a mobility ratio of 3.8 in combination with a highly permeable sand and steam desaturated area would not allow the formation of an effective immiscible displacement bank. The monitoring program demonstrated that oil resaturation occurred in areas where the injection water filled the steam desaturated zone. Temperature data from observation wells showed that hot water was ineffective at transferring heat to the reservoir.
