This paper presents a set of guidelines that field engineers can use for the optimum conversion of maturing steamflood projects to waterfloods. The guidelines were developed based on a simulation study of Chevron's oldest steamflood-followed-bywaterflood project, the Kern River Ten-Pattern project in California. They have been validated against different reservoirs and operating conditions. The simulation study showed that by judiciously converting a steamflood to a waterflood as the steamflood matures, the cumulative net saleable oil (cumulative oil produced minus oil used as steam generator fuel) can be maximized. The optimum time of conversion has been characterized in terms of eight performance variables that can be monitored in the field. A field engineer can use these characteristics or guidelines to estimate the optimum time of conversion and use this result to maximize the net saleable oil production from his project. The procedures used for developing the guidelines from the Kern River Ten-Pattern project performance and for validating them against different reservoirs and operating conditions are presented in this paper. The recommended procedure for applying these guidelines to other fields is also discussed.
