Volume 3, Issue 3 , July 2018, Pages 207-218

https://doi.org/10.22090/jwent.2018.03.002

Abstract
  Oil production from oil reservoirs containing oil in water (O/W) and water in oil (W/O) emulsions has always been accompanied by some problems. The increase in apparent viscosity of the oil, pore throats blockage, and consequently, the increased rate of pressure drop are among these problems. Investigating ...  Read More
