  • What is the viscoelasticity oil displacement mechanism of BD-HMHEC solution?
  • The viscoelasticity oil displacement mechanism of a BD-HMHEC solution is discussed as follows based on the incremental oil recovery determined according to the visual evaluation. A schematic of the flooding process of oil droplets in water-wet cores. Visual evaluation of BD-HMHEC solution oil displacement.
  • What are the microscopic profile control and Oil Displacement Mechanisms of mpems?
  • The microscopic profile control and oil displacement mechanisms of MPEMs in porous media mainly behave asselective-plugging in large pores, fluid diversion after MPEMs plugging, oil drainage caused by MPEMs breakthrough, and the mechanism of oil droplets converging into oil flow.
  • Does hydrolyzed polyacrylamide improve oil recovery?
  • Core flooding experiments show that the oil recovery of the novel surface active polymer is 5.2% higher than that of ordinary hydrolyzed polyacrylamide because of its better viscosifying performance and lower oil/water interfacial tension.
  • What is micron-size polyacrylamide elastic microsphere?
  • Micron-size polyacrylamide elastic microsphere (MPEM) is a newly developed profile control and oil displacement agent for enhanced oil recovery in heterogeneous reservoirs. In this study, laboratory experiments were performed to characterize the viscoelastic properties of MPEMs in brine water.
