MICRO-SLUG INJECTION OF SURFACTANTS IN AN ENHANCED OIL RECOVERY PROCESS |
摘要 |
A method for introducing a surfactant into an oil bearing formation includes plurality of a micro-slug injections of surfactant. Each micro-slug injection comprises an "on time" in which the surfactant is introduced into the formation and which is based upon the time needed for the surfactant to generate foam in the formation and a "off time" in which surfactant flow is stopped and is based upon the time period for the generated foam to degrade to a predetermined degree in the formation.
