The oil and gas industry is constantly seeking innovative solutions to maximize resource extraction and optimize operational efficiency. Polyacrylamide (PAM), particularly Anionic Polyacrylamide (APAM), has emerged as a critical chemical additive in oilfield operations, primarily for Enhanced Oil Recovery (EOR) and friction reduction in hydraulic fracturing. As a leading manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides high-performance PAM solutions vital for these advanced applications.

Enhanced Oil Recovery (EOR)

Conventional oil extraction methods typically recover only a fraction of the oil in a reservoir. Enhanced Oil Recovery (EOR) techniques are employed to recover additional oil that remains trapped in the porous rock formations. Polymer flooding, a common EOR method, utilizes polymers like APAM to increase the viscosity of injected water. This works in two primary ways:

• Improved Sweep Efficiency: By increasing the viscosity of the injection fluid, APAM helps to push the oil more effectively through the reservoir, preventing the water from bypassing oil-rich zones. This leads to a more uniform sweep of the reservoir.
• Mobility Control: APAM reduces the mobility difference between the injected water and the oil. This prevents viscous fingering, where lower-viscosity water channels through the oil, leaving significant amounts of oil behind. By controlling mobility, APAM ensures that more oil is mobilized and recovered.

The effectiveness of APAM in EOR is highly dependent on its molecular weight and stability under reservoir conditions (temperature, salinity, shear stress). High molecular weight APAM is generally preferred for its superior thickening capabilities.

Friction Reduction in Hydraulic Fracturing

Hydraulic fracturing, or fracking, is a technique used to extract oil and natural gas from low-permeability reservoirs. It involves injecting a fluid under high pressure into a wellbore to create fractures in the rock. This process requires pumping large volumes of fluid, and the friction generated between the fluid and the wellbore walls can significantly increase pumping pressures and energy consumption. Polyacrylamide derivatives are widely used as friction reducers in these fluids.

APAM, when added to fracturing fluids, can dramatically reduce friction losses. The long polymer chains align with the flow, smoothing the turbulent eddies near the wellbore wall and reducing the energy required for pumping. This allows for higher pumping rates, deeper penetration into the reservoir, and reduced operational costs.
