An Experimental Study of Polymer Flooding to Enhance Oil Recovery: دراسة تجريبية للغمر بالبوليمر لتعزيز استخلاص الزيت

Abstract

Experimental investigation of the impact of a synthetic polymer used to enhance oil recovery in an Egyptian oilfield was the goal of the current study. According to the findings of the current study, polymer solutions display non-Newtonian flow behavior under a variety of temperature, salinity, and shear rate conditions. The shear rate, salt level, temperature, and solution concentration all affect the apparent viscosities of polymer solutions. Studying how salinity and temperature affect how polymer solutions of various concentrations flow through porous media revealed that, up to a certain point, the mobility of the solutions increases with the flow rate, after which the mobility decreases with the flow rate. The mobility as a function of water saturation showed that during the tertiary recovery stage as compared to that during the secondary recovery stage, both the water mobility and the total mobility greatly reduced, and the oil mobility somewhat rose. The mobility analysis suggested that motion might be important in understanding how these processes increase oil recovery.
