Mobility control and enhanced oil recovery using partially hydrolysed

Polymers are often used as mobility controller for enhanced oil recovery. The present paper deals with the application of partially hydrolysed polyacrylamide (PHPA) polymer in enhanced oil recovery after the conventional water flooding. Experimental results show that viscosity of PHPA solution increases significantly on addition of small quantity of polymer, which in turn decreases the

acrylamide are widely used for EOR, with Partially Hydrolyzed Polyacrylamide (PHPA) being used the most. However, this polymer has low stability under harsh reservoir conditions (High Temperature and Salinity ¨C HTHS).

Experimental evaluation of partially hydrolyzed polyacrylamide

Chemical flooding using water-soluble polymers like partially hydrolyzed polyacrylamide (PHPA) has been industrially used as an EOR technique. The paper deals with the effect of nano-silica particles on viscosity as well as the shear rate of the polymer solution.

Comparative Study of Polyacrylamide Co-polymers for EOR at High

While polymers PHPA and co-polymers AM-AMPS and AM-nVP showed typical Newtonian behavior at low shear rates and non- Newtonian at high shear rates, HMPAM polymers have shear thinning behavior. Newtonian behavior on PHPA-3 seems to support its higher recovery factor comparing with PHPA-6 (higher MW).

In the oil displacement test, the oil recovery ratio of P-GO-O nanofluid (17.2%) was higher than the GO-O (octadecylaminated graphene oxide) nanofluid (6.7%), which was attributed to its better stability and wettability alteration. These results indicated that the P-GO-O nanofluid had the potential for enhanced oil recovery (EOR) application.

A review on advanced nanoparticle-induced polymer

Polymer flooding is an EOR method that involves the injection of aqueous high molecular weight polymer solution into oil reservoirs and works on the principle of mobility control owing to its high viscosity (Bera et al., 2020, Uranta et al., 2019). However, the efficiency of injected polymers is retarded by harsh reservoir conditions such as
