- 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 is modified polyacrylamide drilling fluid?
- Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
- 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 hydrophobically modified polyacrylamide gel be used in high temperature drilling?
- Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2025.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.
