Some Key Features to Consider When Studying Acrylamide-Based Polymers for Chemical Enhanced Oil Recovery

Abstract: Le succès d'un projet d'injection de polymères commence avec la sélection du produit adapté aux caractéristiques du réservoir telles que la qualité d'eau, la température, la perméabilité ainsi que la présence éventuelle de contaminants comme le fer, l'hydrogène sulfuré et l'oxygène. Des études de stabilité menées à long terme en laboratoire permettent de s'assurer de la bonne tenue du produit tout au long de l'injection, tandis que des expériences d'injection sur carottes sont utiles pour vérifier l'injectivit… Show more

“…With a broader distribution of charge between the different polymer molecules, the solutions of PHP contain a larger fraction of polymer chains with lower and higher degrees of hydrolysis, relative to the mean value, compared to solutions of CPP ( Figure 2). In this case, assuming equal molecular weights, 4 Viscoelastic Behavior. G′, G′′, and loss tangent, tan δ = G′′/G′, are plotted as a function of oscillation frequency for solutions of PHP and CPP at high (0.344 M) and low (0.086 M) total ionic strengths in Figures 3 and 4.…”

“…With respect to industrial-scale manufacturing of HPAM by posthydrolysis of PAM, the posthydrolysis step commonly occurs on grains of insoluble PAM. 4 This is different from the laboratory procedure used by Truong et al 1 where alkaline hydrolysis was performed on aqueous PAM solutions. Consequently, the industrial process is affected by diffusion of the alkali into the PAM grains as well as the kinetics of the hydrolysis step.…”

“…Polyacrylamide (PAM), a water soluble polymer, is widely used in EOR due to its compatibility with other chemicals and cost-effectiveness (Thomas et al, 2012). Gogarty (1978) found that the addition of polymer in chemical solution improved the mobility ratio by controlling the mobility of displaced phase.…”

“…This behaviour of the polymer gel is known as pseudo-plastic behaviour, and it can occur when PAM solution is injected into a reservoir from the injection well [28][29][30]. The flow regime usually changes as the solution flows first through the wide well-bore and finally to the reservoir.…”

“…Mechanical degradation through shearing devices can lead to significant reductions in viscosity described as a reversible decrease in viscosity with increasing shear rate (shear thinning). This behaviour of the polymer gel is known as pseudo-plastic behaviour, and it can occur when PAM solution is injected into a reservoir from the injection well [28][29][30]. The flow regime usually changes as the solution flows first through the wide well-bore and finally to the reservoir.…”
