Thermal and Chemical Stability of PAM Under Harsh Oilfield Conditions

In oilfield operations, polymer flooding and other enhanced oil recovery (EOR) techniques rely heavily on the performance of chemical additives. Among them, oilfield polyacrylamide plays a crucial role in improving sweep efficiency, reducing water production, and enhancing crude oil displacement. However, the success of these applications depends on the polymer’s ability to remain stable under high temperature and aggressive chemical environments typically found in oil reservoirs.

Why Stability Matters in Oilfields

Oil reservoirs often present harsh conditions—high salinity, elevated temperatures, and the presence of multivalent ions. These factors can degrade many conventional polymers over time, reducing their viscosity and effectiveness. A polymer used in such environments must exhibit both thermal stability and chemical resistance to maintain performance during long-term injection.

Key Performance Features of Oilfield Polyacrylamide

Through careful formulation, oilfield polyacrylamide is designed to retain its molecular weight and functional groups even under prolonged exposure to extreme conditions.

Applications in Harsh Oilfield Environments

The most common uses of oilfield polyacrylamide include:

• Polymer flooding for enhanced oil recovery

• Drilling fluid additives for friction reduction

• Profile control and water shutoff treatments

• Formation stabilization and permeability control

In each application, performance hinges on the polymer's ability to remain active throughout the process. Poorly stabilized polymers may break down prematurely, leading to reduced oil recovery and higher operating costs.
