Cellulose Nanocrystal–Polyelectrolyte Hybrids for Bentonite Water-Based …
Cellulose nanocrystals (CNCs), with their rodlike shape and nanoscale dimensions, greatly improve the filtration performance of bentonite-containing, water-based drilling fluids (BT-WDFs) through interactions with the BT platelets. When these WDFs are exposed to high salt concentrations, though, their fluid retention properties are greatly diminished due to reduced CNC-BT interaction and BT …

Recent advances of modified polyacrylamide in drilling technology
Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.

Application of polymeric drilling fluids for reducing wearing of drill …
The aqueous solutions of polymeric fluid additives i.e. carboxymethyl cellulose (CMC), Guar gum (GG), and Polyacrylamide (PAM) at a concentration of 10 ppm, have been used as drilling fluid. These fluids are expected to have the ability to reduce frictional heat at the bit-rock interface by lubricating it and also dissipating the heat from the bit.
