Abstract

An oil/water separation agent Drows-1, formulated mainly with nonionic and anionic active components, has been developed for ASP flooding produced oil containing water. The newly developed oil/water separation agent shows both good flocculating-coalescing and flotation effects on the oil droplets in ASP flooding produced oil containing water. It shows also good demulsifying effect on O/W type ASP flooding produced liquid, resulting in low oil content in water phase after phase separation of ASP flooding produced liquid. Based on the performance of the newly developed oil/water separation agent, a thermo chemical settling-flotation process, in which the newly developed oil/water separation agent is injected into ASP flooding produced liquid upstream of free water knock out, is proposed for the oil/water separation of ASP flooding produced oil containing water.
