Mud Chemical Phpa / Eor / Drilling Fluid / Oilfield
PHPA is effective in fresh and salt water drilling fluids, minimizing the build up of solids in drilling fluids. Also it is effectively prevents clay and shale problem such as welling, sloughing, bit balling and mud rings. Prevents dispersion and swelling shales and clays by way of encapsulation.

PHPA Partially Hydrolyzed Polyacrylamide Suppliers
PHPA (also partially hydrolyzed polyacrylamide or HPAM) is designed for easy mixing in drilling mud systems and to improve its dispersion to eliminate “fish eyes”, This occurs in field work when mixing either large quantities rapidly or mixing high polymer concentrations without good mixing equipment.In drilling fluids, PHPA is an anionic polyacrylamide and it can act as a viscosifier
A class of water muds that use partially-hydrolyzed polyacrylamide (PHPA) as a functional additive, either to control wellbore shales or to extend bentonite clay in a low-solids mud.As a shale-control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration. KCl is used as a shale inhibitor in most PHPA mud designs.

- What is copper-catalyzed controlled polymerization of acrylamide?
- Copper-catalyzed controlled polymerization of acrylamide (AM) has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (MWD) or requires complex/multistep reaction procedures, due to the highly active nature of the AM radical and its side reactions.
- Which acrylamides provide more than 90% m in 1d-initiated polymerizations?
- Alkyl-substituted acrylamides including N, N -diethylacrylamide ( 2b, DEAA) and N -isopropylacrylamide ( 2c, NIPAM) provided more than 90% m in 1d -initiated polymerizations with addition of 5 mol% La (OTf) 3. A wide range of polar pendants were well-tolerated, including ether, amine, alcohol and cation.
- Are bimetallic catalysts able to control radical polymerization?
- The backbone stereoregularity that dictates a broad range of polymer properties cannot be readily controlled in radical polymerizations. Now, bimetallic catalysts containing covalently bridged rare earth and cobalt complexes enable stereocontrolled living radical polymerization of acrylamides tethered with diverse polar and ionic pendant groups.
- Why is radical polymerization important in aqueous dispersed systems?
- A significant advantage of RDRP among the various living polymerization processes is its water tolerance, which is attributable to the negligible side reactions that occur between the radical and water molecules. Therefore, radical polymerization in aqueous dispersed systems has been developed extensively thus far [ 1, 26, 27, 28, 29, 30 ].
