Recent advances of modified polyacrylamide in drilling

There are various studies on polyacrylamide-based drilling fluid, including its modification and improvement, in recent years. Magzoub et al. (2021) utilised the anionic polyacrylamide-based drilling fluid that was formed by polymerisation of acrylamide monomer. This polymerisation also involved a bifunctional crosslinking agent

Thermally stable and salt-resistant synthetic polymers as

Different types of SP have been evaluated at such conditions for water-based drilling fluids (WBDF) and oil-based drilling fluids (OBDF). These include various monomers, such as 2-acrylamido-2-methyl-1-propane sulfonic acid [45] , and ally-polyoxyethylene ether [46] , homopolymers [47] , and copolymers [3] used to construct SP [48] .

Water Soluble Polymer Flocculants: Synthesis

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

Experimental lab approach for water based drilling fluid

The objectives of this paper are: (1) to present the possibility of using polyacrylamide based FRs in water base drilling fluids to replace oil based drilling fluids used to drill long lateral sections; (2) to show the optimal pH values of the newly developed FR water base drilling fluids; and (3) to present the effect of FR on both drilling

Abstract. A water-based drilling fluid comprises a polymer which is a non-ionic polymer or an anionic polymer. The polymer can be a polyacrylamide. The fluid is used for drilling subterranean formations containing heavy crude oil and bitumen-rich oil sands, and may comprise additional fluid components.
