mobility control and enhanced oil recovery using partially

Mobility control and enhanced oil recovery using partially

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

Polymer viscosifier systems with potential application

Among the chemical methods, the use of polymers stands out to increase the viscosity of the injection fluid and harmonize the advance of this fluid in the reservoir to provide greater sweep efficiency. Synthetic polymers based on acrylamide are widely used for EOR, with Partially Hydrolyzed Polyacrylamide (PHPA) being used the most.

Recent advances of modified polyacrylamide in drilling

Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.

Figure 2 (c) represents the chemical structure of partially hydrolyzed polyacrylamide (PHPA). The molecular weight of this polymer is 17,000,000 g/mol (Jefferis et al. 2015 ). It is classified as synthetic polymer that mainly consists of repeating blocks of acrylates and acrylamides (Jefferis et al. 2015 ).
