An Experimental Study of Tapioca Starch-Polyacrylamide Grafted Polymer in Enhanced Oil Recovery

The oil industry is currently facing pressing challenges to increase well productivity. Both primary and secondary recovery methods can recover up to 30 to 50 % of original oil in place. In this situation, a tertiary recovery is needed. Polymer flooding is able to increase the oil production comp...
