The extraction of crude oil from reservoirs is a complex process, and achieving maximum yield often requires sophisticated chemical interventions. Among these, high viscosity polymers play a critical role, and at NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing cutting-edge solutions in this domain. Our Nonionic Polyacrylamide (PAM) is a prime example of a high viscosity polymer for oil extraction that significantly enhances reservoir productivity.

In conventional water flooding, water is injected into the reservoir to push oil towards production wells. However, water is often much less viscous than the oil it is meant to displace. This viscosity difference leads to an unfavorable mobility ratio, where the water tends to bypass the oil, flowing through the path of least resistance (high permeability zones) and leaving a substantial amount of oil behind. This reduces the overall oil recovery efficiency.

This is where polymers like PAM come into play. By dissolving PAM in the injection water, its molecular structure dramatically increases the viscosity of the water. This enhanced viscosity improves the mobility ratio, making the injected fluid more viscous and more capable of sweeping the oil uniformly across the reservoir. This process, known as polymer flooding, is a key component of Enhanced Oil Recovery (EOR). The improved volumetric sweep efficiency ensures that more of the reservoir’s oil is mobilized and produced.

Our Nonionic Polyacrylamide is particularly well-suited for EOR applications due to its stable performance under various reservoir conditions. Its molecular weight and concentration can be precisely controlled to achieve the desired viscosity profile. The ability of PAM to maintain its viscosity and resist degradation is crucial for long-term effectiveness in the reservoir. As experts in nonionic polyacrylamide for enhanced oil recovery, we understand the critical parameters that influence polymer performance.

Beyond viscosity enhancement, PAM can also help in reducing the permeability of high-permeability zones, forcing the injected water into less swept areas. This 'conformance control' further improves the efficiency of oil recovery. While its primary application in oil extraction is well-known, the principles of viscosity modification are also leveraged in other industries, such as in fracking fluids where it acts as a friction reducer and proppant carrier, as highlighted in our discussions on pam for fracking applications.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to innovation in polymer science. We continuously work on developing PAM formulations that offer enhanced thermal stability, salinity tolerance, and shear resistance, ensuring their efficacy even in the most challenging reservoir environments.
