Abstract

Summary

One of the major issues of polymer flooding in EOR is the loss of polymer material during injection due to retention/adsorption and even the formation damage because of other mechanical phenomena. So, operating companies usually look for minimizing this polymer loss.

To understand the retention of polymers in reservoir rocks, we carried out several core flood experimental studies by investigating the influence of rock nature and permeability (high and intermediate permeability considering Bentheimer and Berea sandstones), polymer molecular weight (low and high), and concentration of polymer solutions (from dilute to semi-dilute).

Under monophasic conditions and high permeability, we show that the polymer retention if corrected for inaccessible pore volume (IPV) depends on polymer concentration regime: retention increases rapidly with polymer concentration (Cp), in the dilute regime and increases then very weakly in the semi-dilute regime. Moreover, the use of low polymer weight results in a high material loss, and in case of high molecular weight and low permeability, plugging is evidenced.

Besides, diphasic tertiary experiments were performed under water-wet and intermediate wet conditions. The first set of experiments was performed on the native water-wet Bentehimer porous medium. The second set of experiments was performed by altering first the wettability of the same porous media, by submitting them to ageing in presence of crude oil.

Our results mainly show that the polymer retention decreases when the oil is present in the porous system due to additional inaccessible pore volume as the added volume is now occupied by residual oil. However, the retention is even smaller in intermediate wet porous media because the pore surface is partially filled by oil. A phenomenological explanation is proposed that supports such observed behaviors.
