The oil and gas industry constantly seeks innovative methods to maximize hydrocarbon recovery from mature reservoirs. Enhanced Oil Recovery (EOR) techniques are vital in this endeavor, and Anionic Polyacrylamide (APAM) has proven to be a highly effective polymer for specific EOR applications, particularly in polymer flooding.

Polymer flooding involves injecting a polymer solution into the reservoir to increase the viscosity of the injected water. This enhanced viscosity reduces the mobility of the water, allowing it to sweep more oil from the reservoir rock towards production wells. APAM, with its high molecular weight and ability to form highly viscous aqueous solutions even at low concentrations, is ideally suited for this purpose. The increased viscosity of the injection fluid helps to improve the sweep efficiency, pushing more oil and minimizing the amount of water bypassing oil pockets.

The selection of the appropriate APAM grade for EOR is critical and depends on reservoir characteristics such as temperature, salinity, and shear rates. The polymer must remain stable under reservoir conditions and maintain its thickening properties throughout the injection process. Manufacturers provide various grades of APAM designed to withstand harsh reservoir environments, ensuring sustained performance.

Beyond viscosity modification, APAM's anionic nature can also play a role in reservoir conformance control, helping to reduce water channeling through high-permeability zones and improving the overall oil displacement efficiency. This targeted approach ensures that injected water is effectively utilized to extract more oil.
