Abstract

The application of crosslinked-polymer systems for permeability modification of petroleum reservoirs has received increasing attention in recent years. A crosslinked-polymer treatment, in general, involves an injection of a polymer solution into high-permeability zones or fractures which have been previously swept by the displacing fluid1. The polymer solution reacts, either before or after injection, to form a three-dimensional gel network which reduces the effective permeability of the invaded portions of the reservoir. Fluid subsequently injected is diverted to other, tighter regions of the formation, thereby improving overall volumetric sweep efficiency.
