The petroleum industry constantly seeks innovative methods to maximize hydrocarbon extraction from existing reservoirs. Enhanced Oil Recovery (EOR) techniques are vital in this pursuit, and Anionic Polyacrylamide (APAM) plays a significant role. NINGBO INNO PHARMCHEM CO.,LTD. provides specialized APAM grades crucial for optimizing EOR processes.

In EOR, particularly through polymer flooding, APAM is injected into the reservoir along with water. Its primary function is to increase the viscosity of the injected water. This increased viscosity is critical because it improves the 'sweep efficiency' of the injection process. Without polymers, water injected into an oil reservoir tends to bypass the oil, flowing through the more permeable zones due to its lower viscosity. APAM, by thickening the water, ensures that it contacts and displaces a larger volume of oil, including from less permeable areas, thereby increasing the overall oil recovery rate.

The effectiveness of APAM oil recovery is directly related to its molecular weight and concentration. High molecular weight APAM polymers are particularly effective at generating the necessary viscosity at low concentrations. This not only makes the process more economical but also helps prevent excessive pressure buildup within the reservoir. The stability of APAM under reservoir conditions, including temperature and salinity, is also a key factor in its successful application.

Furthermore, APAM's role as a friction reducer in hydraulic fracturing operations is also notable, although its primary EOR application lies in viscosity modification. The ability to precisely tailor the properties of APAM makes it a valuable tool for reservoir engineers aiming to enhance oil production. NINGBO INNO PHARMCHEM CO.,LTD. understands these critical requirements and provides APAM that meets the stringent demands of the oil and gas sector.

By improving the sweep efficiency and facilitating more effective oil displacement, APAM contributes significantly to the economic viability of mature oil fields. As a key player in the supply of water treatment chemical APAM and industrial polymers, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supporting the petroleum industry's efforts to maximize resource utilization.
