The global demand for oil and gas continues to drive innovation in extraction technologies. While primary and secondary oil recovery methods are effective, a significant portion of oil often remains trapped in reservoir formations. This is where Enhanced Oil Recovery (EOR) techniques come into play, and among the most prominent chemical EOR methods is polymer flooding, which heavily relies on Polyacrylamide (PAM).

Polymer flooding involves injecting polymer solutions into oil reservoirs to increase the viscosity of the injected water. This increase in viscosity is crucial for several reasons. Firstly, it helps to improve the sweep efficiency of the injected water. In reservoirs with varying permeability, water tends to flow through the more permeable zones, bypassing oil in less permeable areas. By increasing the viscosity of the injected water, PAM forces it to flow more uniformly through the reservoir, reaching more of the trapped oil.

Secondly, PAM helps to improve the oil-displacement efficiency by reducing the mobility ratio between water and oil. A lower mobility ratio means that the injected fluid is more effective at pushing the oil forward. PAM achieves this by thickening the water phase, thus reducing its ability to flow unimpeded through the porous rock. This results in more oil being displaced towards the production wells.

The selection of the appropriate type of Polyacrylamide for EOR is critical and depends on several reservoir characteristics, including temperature, salinity, shear rate, and rock permeability. Hydrolyzed Polyacrylamide (HPAM) is frequently used due to its excellent thickening capabilities in a wide range of conditions. The molecular weight and degree of hydrolysis of the PAM are key parameters that influence its performance. Higher molecular weight polymers generally provide better viscosity and sweep efficiency, while the degree of hydrolysis affects the polymer's solubility and interaction with reservoir rock.
