Demulsifier for separation of liquid obtained in chemical flooding of oil layers

  • RESEARCH
  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

The development and use of a demulsifier for separation of the fluid obtained after flooding of an oil layer using ASP (alkaline surfactant polymer) are described. The mechanism of separation of the emulsion was investigated. As a result of laboratory studies and tests in the field, it was shown that the demulsifier produces excellent results in separation of such emulsions.
