Polyacrylate Polyacrylamide and PHPA - Drilling Fluids
Acrylonitrile is polymerized to form polyacrylonitrile which is then partially hydrolyzed to form acryla-mide and acrylic acid groups along the polymer chain (see Figure 16). These polymers are referred to as PHPA, (partially hydrolyzed polyacrylamide), and are used as clay extenders, flocculants, and encapsulating colloids.
We offers 1,613 polyacrylamide phpa products. About 77% of these are petroleum additives, 51% are paper chemicals, and 45% are water treatment chemicals. A wide variety of polyacrylamide phpa options are available to you, such as coating auxiliary agents, petroleum additives, and leather auxiliary agents.

SPE Drilling Engineering | SPE
Laboratory tests showed that the greatest improvement in shale inhibition was obtained, not from cationic polyacrylamide, but from a mixture of conventional PHPA and a cationic starch. [Cationic starch is prepared by reacting potato starch with either 2-dimethylaminoethyl chloride or n-(2,3-epoxypropyl)-trimethyl ammonium chloride.]

Polyethylene Glycol Drilling Fluid for Drilling in Marine
Shale inhibition, low-temperature performance, the ability to prevent calcium and magnesium-ion pollution, and hydrate inhibition of polyethylene glycol drilling fluid were each tested with conventional drilling-fluid test equipment and an experimental gas-hydrate integrated simulation system developed by our laboratory. The results of these tests show that drilling fluid with a formulation of

US9022120B2 - Dry polymer mixing process for forming
Apparatus, methods and systems for preparing a polymer concentrate for treating a formation with slick water systems viscous fluid or a gelled viscous fluid are disclosed. The method includes directing a powdered gel into a vortex mixing chamber, while directing a first portion of a base fluid into the vortex mixing chamber to form partially hydrated fluid concentrate.
Henna leaf extracts (HLE) was used to formulate henna water-based mud (HWBM) and its performance on cuttings transport efficiency (CTE) was compared with bentonite water-based mud (BWBM) and fresh water. Tests were conducted in a laboratory-scale flow-loop equipped with a 16-ft-long test section consisting of a concentric annulus outer casing (3.5-in. ID) and a static inner drill-pipe (2.4-in ...
