Polymer flooding
WebApr 8, 2014 · We propose a mathematical model (numerical simulation) of surfactant-polymer flooding for a three-phase six-component system. The model takes into account various phenomena inherent to flooding, the effect of surfactant—polymer interactions on the viscosity, interfacial tension, and adsorption. We simulated the behavior of different … WebPolymer flooding is an important enhanced oil recovery technol. introduced in field projects since the late 1960s. The key to a successful polymer flood project depends upon proper estn. of polymer retention. The aims of this paper are twofold. First, to show the mechanism of polymer flooding and how this mechanism is affected by polymer retention.

Web1 day ago · 1.Introduction. In most low-permeability sandstone reservoirs, potential challenges to water flooding include early water breakthrough and a rapid rise in water cut, which limit the recovery of hydrocarbons from the reservoir (Okeke and Lane, 2012; Xie et al., 2024).The more the layer heterogeneity increases, the more severe the problem of fluid … WebJan 2, 2024 · In polymer flooding, polymer can be retained in porous media through precipitation, adsorption, or mechanical entrapment. As a result, formation damage can occur. Therefore, core flow tests should be conducted to examine the potential formation damage problems during polymer flooding processes prior to field application [ 18 , 19 ].
