The potential of TPA to enhance its viscosity in extremely high salinity brines is explained by the antipolyelectrolyte effect, resulting inside the unfolding of macromolecular chains of charge-balanced polyampholytes at a quasi-neutral state, which happens as a consequence of the screening of your electrostatic attraction among oppositely charged moieties. The novelty of this investigation is that, in high-salinity reservoirs, the amphoteric terpolymer Aam-AMPS-APTAC might surpass HPAM in oil displacement capability.PMID:23381626 Citation: Gussenov, I.S.; Mukhametgazy, N.; Shakhvorostov, A.V.; Kudaibergenov, S.E.

Introduction Water flooding would be the most broadly used oil recovery process. However, in numerous reservoirs, water cannot provide a steady oil displacement front on account of the unfavorable mobility ratio involving these fluids, which outcomes in viscous fingering, specifically in highviscosity oil reservoirs. In addition, permeability heterogeneities can also result in premature water breakthrough, and, because of this, less oil is made than would happen to be achievable with far better conformance manage [1]. Such problems could be solved by rising the water viscosity, ergo water-soluble polymers are utilised for this purpose, typically at low concentrations.
