| 摘要 |
Opaque macroemulsions comprising oil and brine are diluted with water to an electrolyte concentration at which rapid coalescence into three phases, oil, a transparent microemulsion, and water is achieved. This is of particular utility in post-primary oil recovery processes wherein said opaque macroemulsions are produced as effluents from producing wells. The opaque macroemulsions are collected and oil therein recovered by dilution as described herein.
