Product Description: Anionic Polyacrylamide PAM For Water Treatment Polyacrylamide is a linear high-molecular polymer. The product is mainly divided into two forms: dry powder and colloid. According to its average molecular weight, it can be divided into three types: low molecular weight (<1 million), medium molecular weight (2 to 4 million) and high molecular weight (> 7 million).

- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
- Can an anionic polymer withstand drilling fluid?
- The fluid loss test on this drilling system found that anionic polymer can resist about 4.5 × 105 ppm of Cl −, 4 × 105 ppm of Ca 2+, and 1.5 × 104 ppm of Mg 2+ at low pH by adding the acidic gas together at 180 °C. Thus, it can withstand the temperature of drilling fluid up to 180 °C.
- Can polyacrylamide be used for drilling?
- However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).
- What are the advantages of polyacrylamide compared to bentonite?
- Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent. Compared to bentonite, the modified polyacrylamide can contribute to many environmental and operational advantages such as a smaller site footprint, ease of mixing, cheaper disposal cost, and less pollution.
