Numerical Modeling of Reservoir Rock Treatment Processes with Polyacrylamide

Increasing the quantities of crude oil extracted from depleted deposits can be achieved using tertiary exploitation methods, namely water injection and polyacrylamide plugs. The adsorption on the surface of the rocks determined the reduction of the mobility of the polymer but also the modification of the gel structure by the modification (crossing) of the polymer (of the polymer chains), which led to clogging (blocking of the pores) and increasing the possibility of fluid flow. Polyacrylamide as a polymer to improve the final recovery factor aims to achieve a good flow of crude oil. In this article, the equations of polymer flow through sands and limestones have been established.
