Demulsifier for produced oil-in-water emulsions containing spent mud acids |
| abstract |
Stable oil-in-water emulsions in produced fluids from wells undergoing acidization treatments are demulsified by treatment of the produced fluids with a long chain carboxylic acid ester of a polyhydric alcohol such as sorbitan monolaurate, surbitan monopalmitate or sorbitan monooleate as a demulsification agent. |
