The oil and gas industry constantly seeks innovative solutions to optimize production, reduce costs, and improve operational efficiency. Polyacrylamide (PAM) has proven to be an invaluable chemical additive in various oilfield applications, primarily due to its unique rheological properties, including its ability to significantly increase fluid viscosity and reduce friction. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-performance PAM grades suitable for the demanding conditions of oilfield operations. PAM in Enhanced Oil Recovery (EOR) In mature oil fields, conventional waterflooding often leaves a significant amount of oil trapped in the reservoir rock. Enhanced Oil Recovery (EOR) techniques are employed to mobilize this residual oil. Polymer flooding, a key EOR method, utilizes PAM to increase the viscosity of the injected water. This enhanced viscosity improves the sweep efficiency by: * Reducing Mobility Ratio: A higher viscosity injected fluid moves more uniformly through the reservoir, preventing viscous fingering where less viscous water bypasses the oil. * Improving Displacement Efficiency: The viscous polymer solution exerts greater pressure on the oil trapped in the pore spaces, pushing it towards the production wells. Anionic PAM (APAM), particularly hydrolyzed polyacrylamide (HPAM), is widely used in EOR due to its effectiveness in saline conditions and high temperatures often encountered in reservoirs. The selection of PAM for EOR depends on reservoir characteristics such as temperature, salinity, shear rate, and rock permeability. Our technical team can guide you in selecting the optimal PAM for your specific EOR project. PAM in Drilling Fluids and Hydraulic Fracturing 1. Drilling Fluids: PAM serves as a crucial additive in drilling fluids. Its functions include: * Viscosifier: Increases the viscosity of drilling muds, enabling them to carry rock cuttings efficiently to the surface. * Shale Stabilizer: Reduces the hydration and swelling of clay-rich formations (shales) that can cause borehole instability. PAM molecules adsorb onto the clay surfaces, preventing them from absorbing water and expanding. * Fluid Loss Control: Helps to reduce the filtration of drilling fluid into the reservoir formation, maintaining wellbore integrity. 2. Hydraulic Fracturing: In hydraulic fracturing, PAM is primarily used as a friction reducer. High molecular weight PAM, when injected into fracturing fluids at low concentrations, significantly reduces the turbulent friction encountered during pumping. This allows for: * Lower pump pressures required to inject the fluid. * Increased proppant carrying capacity. * Reduced energy consumption and wear on pumping equipment. * Improved fluid efficiency. Selecting the Right PAM for Oilfield Applications: Oilfield PAMs often require specific properties to withstand harsh reservoir conditions, including high temperatures, high salinity, and high shear rates. Cationic PAMs may offer better performance in high salinity environments due to reduced electrostatic repulsion. However, APAM, especially with modifications for temperature and shear stability, remains a dominant choice. Why Partner with NINGBO INNO PHARMCHEM CO.,LTD.?
