Enhanced Oil Recovery (EOR) is a critical phase in oil field development, aimed at maximizing the extraction of crude oil from reservoirs that have been depleted by primary and secondary recovery methods. Among the various EOR techniques, polymer flooding stands out as a cost-effective and efficient method. At the heart of polymer flooding is the application of high molecular weight water-soluble polymers, with Polyacrylamide (PAM) being a leading choice. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing high-quality polyacrylamide solutions for these demanding applications.

The fundamental principle behind polymer flooding is to increase the viscosity of the injected water. By adding a specific concentration of PAM to the injection water, its viscosity is significantly elevated. This higher viscosity alters the mobility ratio between the injected fluid and the reservoir oil. A more viscous polymer solution leads to a larger residual resistance coefficient, which in turn improves the flow ratio between the subsurface oil and water. This enhanced flow ratio directly translates to better sweep efficiencies, both macroscopically and microscopically, allowing more oil to be displaced towards production wells. The application of PAM effectively pushes trapped oil from reservoir pores and fractures, leading to a substantial increase in the overall recovery factor.

NINGBO INNO PHARMCHEM CO.,LTD. offers a range of polyacrylamide products tailored for EOR applications, including those designed to withstand high temperatures and salinity levels found in many oil reservoirs. Our expertise in producing polymers with specific molecular weights and charge densities ensures optimal performance in diverse geological conditions. The use of polyacrylamide in EOR projects has been proven to yield significant increases in ultimate oil production, often ranging from 30-60 percent of the reservoir's original oil in place.

For those looking to purchase polyacrylamide for EOR, understanding the technical specifications and choosing the right grade is crucial. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed product information and expert consultation to help clients select the most suitable polyacrylamide for their specific project needs. Investing in high-quality polyacrylamide from a reliable supplier like NINGBO INNO PHARMCHEM CO.,LTD. is a strategic step towards maximizing hydrocarbon recovery and improving the economic viability of oil fields.
