Experimental and modeling Investigation of polymers Flooding for EOR Application in a Micromodel System

Abstract

After the water flooding, 65% of oil is stranded in place. engineers have worked for decades to develop technical solutions to recover it. One such technique consists of injecting viscous water into the formation to displace the oil. The viscosity contrast between the injected water and the viscous oil creates instability and promotes water penetration through the oil or complete bypass of the oil. The objective of this work is to study Analysis and Performance of Enhanced Oil Recovery by Injection of Water-Soluble Polymers in glass micromodel and study simulate in CMG software. This study involves injecting polymers that have effects viscous forces, we compare between Water flooding and Polymers flooding, the results show that the overall water injection efficiency is around 40 % before the EOR, the efficiency jump to 70 % after the EOR.
