- Which polymer is used in water based drilling fluids?
- In conventional water-based drilling fluids, bentonite, natural polymer, and synthetic polymer were discovered in the past. There are many drawbacks to the use of bentonite, natural polymer, and synthetic polymer. Consequently, polymer modification is required in drilling nowadays.
- What is the thermal conductivity of polyacrylamide based drilling fluid?
- It showed thermal conductivity around 0.9 Wm −1 K −1 that have 84% improvement when compared to the bare polyacrylamide. Study of filtration and rheological properties in polyacrylamide-based drilling fluid using graphene oxide

- Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2020.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.
- Does nanosilica increase viscosity of polyacrylamide xanthum gum?
- Corredor-rojas et al. (2018) also investigated the modified polyacrylamide and xanthum gum with the nanosilica. The viscosity of the polymer was increased after the addition of nanosilica as a cross-linker between the polymer chains. Unmodified silica was unable to mitigate the viscosity reduction when temperature increased.
