The global demand for energy necessitates efficient methods for oil extraction. Beyond primary and secondary recovery techniques, Enhanced Oil Recovery (EOR) plays a crucial role in maximizing output from mature oil fields. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the significant impact of specialized polymers, such as Polyacrylamide (PAM), in making EOR processes more effective and economical. Specifically, Partially Hydrolyzed Polyacrylamide (HPAM) has emerged as a key player in this field.

The fundamental challenge in EOR is to mobilize oil that is trapped in the reservoir rock due to factors like high viscosity or unfavorable wettability. Waterflooding, a common secondary recovery method, often faces limitations because water, being less viscous than the oil, can bypass significant amounts of trapped oil. This is where polymers like HPAM come into play. When injected into the reservoir, HPAM significantly increases the viscosity of the injected water.

This increase in viscosity has a profound effect on the sweep efficiency. By matching the viscosity of the injected fluid more closely to that of the oil, HPAM reduces the mobility difference between the oil and water phases. This means the injected water is less likely to finger through the reservoir, bypassing the oil. Instead, it pushes a more uniform bank of oil towards the production wells, leading to a substantial increase in the recovery factor. The effectiveness of HPAM in this role is directly related to its high molecular weight and its ability to maintain this viscosity under reservoir conditions, including temperature and salinity, although careful selection based on reservoir characteristics is essential.

Furthermore, polyacrylamide polymers are also utilized in hydraulic fracturing, a critical technique for stimulating production in unconventional oil and gas reservoirs. In this application, PAM acts as a friction reducer. During the high-pressure pumping of fracturing fluids, friction can build up, requiring more energy and potentially causing damage to equipment. By adding PAM, the fluid's rheology is altered, significantly reducing frictional pressure losses. This allows for higher injection rates, deeper penetration into the formation, and overall more efficient fracturing jobs. The polymer's ability to withstand the shear forces experienced during pumping is key to its success.

At NINGBO INNO PHARMCHEM CO.,LTD., we provide high-quality polyacrylamide products tailored for the demanding conditions of the oil and gas industry. Understanding the specific reservoir characteristics, such as temperature, salinity, and rock permeability, is crucial for selecting the optimal PAM product for EOR or hydraulic fracturing. Our commitment is to supply chemicals that enhance operational efficiency, improve recovery rates, and contribute to the economic viability of oil and gas extraction. The role of polyacrylamide in modern energy production is undeniable, driving innovation and maximizing resource utilization.
