The oil and gas industry constantly seeks innovative methods to maximize hydrocarbon recovery from existing reservoirs. NINGBO INNO PHARMCHEM CO.,LTD. contributes to this effort with the application of Polyacrylamide (PAM) in Enhanced Oil Recovery (EOR) techniques. PAM, particularly its polymer flooding variants, plays a crucial role in improving the efficiency of oil extraction from mature fields.

In conventional oil recovery, a significant portion of oil often remains trapped in the reservoir pores after primary and secondary recovery methods. EOR techniques are employed to recover this remaining oil. Polymer flooding, a common EOR method, involves injecting a solution of a high molecular weight polymer, such as PAM, into the reservoir. The primary function of PAM in this application is to increase the viscosity of the injected water.

Why is increasing water viscosity important for oil recovery? In reservoirs, water tends to flow more easily through the porous rock than oil. This preferential flow of water can lead to 'fingering' or 'channeling,' where water bypasses large volumes of oil, leaving them unrecovered. By increasing the viscosity of the injection water, PAM improves the 'sweep efficiency' of the process. This means the injected water moves more uniformly through the reservoir, pushing a larger proportion of the oil towards the production wells.

The selection of the right PAM for EOR applications is critical. Factors such as molecular weight, shear stability, and resistance to degradation in reservoir conditions (temperature, salinity, and shear) are crucial. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of specifically designed PAMs for EOR that maintain their viscosity and performance under these challenging reservoir environments. The term oil recovery enhanced polyacrylamide refers to these specialized grades.

The benefits of using PAM in EOR include increased oil recovery rates, improved sweep efficiency, and the potential to extend the productive life of mature oil fields. By optimizing fluid flow and reducing water channeling, PAM-based polymer flooding can significantly boost the overall economic viability of oil production.

In addition to polymer flooding, PAM can also be used in other EOR applications, such as in hydraulic fracturing fluids to help control viscosity and sand transport. Its versatility makes it a valuable component in the arsenal of oilfield chemicals.
