Advantages of the product

Superior Molecular Weight and Purity

Our anionic polyacrylamide for oilfield is manufactured with exceptionally high molecular weight and controlled ionic charge, ensuring maximum viscosity and effective flocculation even in low concentrations. The product’s purity minimizes impurities that can interfere with reservoir chemistry, reducing formation damage. This advantage translates to higher sweep efficiency during polymer flooding, leading to increased oil recovery rates. Moreover, the tailored molecular weight distribution ensures rapid dissolution and stable performance across salinity and temperature variations.

Exceptional Salt Tolerance and Thermal Stability

One of the critical challenges in oilfield applications is the presence of high salinity and elevated temperatures, which can degrade polymer performance. Our anionic polyacrylamide for oilfield is specially formulated to withstand these harsh conditions. The polymer exhibits excellent tolerance to divalent cations like calcium and magnesium, preventing precipitation and viscosity loss. This stability ensures consistent performance in reservoirs with high total dissolved solids and temperatures up to 120°C, reducing the risk of polymer degradation significantly.

Versatile Functionality in Drilling and Fracturing

Beyond enhanced oil recovery, our anionic polyacrylamide for oilfield serves multiple roles in drilling, cementing, and fracturing operations. In water-based drilling fluids, it acts as a shale stabilizer and rheology modifier, preventing wellbore instability and improving cuttings transport. Its high viscosity and low friction properties reduce pressure losses during high-volume fracturing, enhancing proppant transport and placement. The polymer also aids in reducing water loss by forming a filter cake on permeable formations.

Anionic polyacrylamide for oilfield is a crucial chemical in modern petroleum engineering, used to enhance oil recovery and manage water-related issues. As reservoirs mature, polymer flooding increases injection water viscosity, improving sweep efficiency. Feymer develops specialized anionic polyacrylamide for oilfield applications, delivering superior performance under extreme conditions to mobilize residual oil and boost production rates.

Frequently Questions

What is anionic polyacrylamide used for in oilfields?

Anionic polyacrylamide is primarily used for enhanced oil recovery through polymer flooding, where it increases the viscosity of injection water to improve sweep efficiency and displace more oil. It is also used as a shale inhibitor and rheology modifier in drilling fluids, as a friction reducer in hydraulic fracturing, and as a flocculant in oilfield produced water treatment. In EOR, the polymer’s high molecular weight and anionic charge allow it to effectively mobilize residual oil by improving the mobility ratio. In drilling, it prevents wellbore instability and controls fluid loss. As a friction reducer, it reduces pumping pressures, enabling efficient fracturing. For produced water treatment, it agglomerates oil droplets and suspended particles, facilitating their removal. Each application requires specific polymer properties, which is why selecting the right grade is crucial.

How does anionic polyacrylamide viscosity change with salinity?

Anionic polyacrylamide is known for its high viscosity in fresh water, but its viscosity can be affected by salinity, especially when divalent ions like calcium and magnesium are present. These ions can interact with the negatively charged groups of the polymer, causing chain coiling and reducing viscosity. However, Feymer’s anionic polyacrylamide for oilfield is specially designed to have excellent salt tolerance. This is achieved by optimizing the polymer’s structure, such as incorporating co-monomers that protect against salts. As a result, our polymer maintains high viscosity even in brines with total dissolved solids exceeding 50,000 ppm. This property is critical for reservoirs with high salinity, where other polymers may lose effectiveness. To ensure proper performance, we recommend conducting a compatibility test under actual reservoir conditions.
