PHPA mud - Schlumberger Oilfield Glossary
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.
Fluid Additives Drilling fluid additives are specialty products that serve a specific need - and Halliburton Baroid is known for high-quality additives that deliver the consistent performance mandated by environmental regulations.
RU2388782C2 - Drilling fluid containing polymer and use
FIELD: chemistry. SUBSTANCE: invention relates to drilling fluids. The drilling fluid contains a polymer which contains at least 65 wt % hydroxylated links of the following formula: -CH 2 -CR 6 [-X 2 -R 8 ]-, where R 6 is a hydrogen atom or methyl group, X 2 is a group of formula -CO-O-, -CO-NH- or -C 6 H 4 -CH 2 -, R 8 is a hydrocarbon group with at least two carbon atoms, which contains at
Drilling fluids material can divide into clay type, weighting material and mud mixing water and oil etc. Bentonite is the main material for water base drilling fluids. It can add viscosity and shearing ability, improve the stability of well hole. Weighting material is grinding from inert substance which is insoluble in water.

Storage of polyacrylamide Store in a cool, dry warehouse and keep it in a safe place with flammable, corrosive and toxic substances. Q: Can I get some free polyacrylamide liquid samples for test9 A: Of course, we could provide small amount free polyacrylamide liquid samples to you for test.
- Which cationic polyacrylamide is used in polymerization?
- The utilized high-pressure ultraviolet lamp is characterized by power of 500–1000 W and predominant wavelength of 365 nm. Another cationic polyacrylamide with intrinsic viscosity of 4.2 dL g −1 was synthesized in 120 min from aqueous photo-polymerization; a 200-W high-pressure mercury lamp was used in polymerization .
- What is cationic polyacrylamide (CPAM)?
- J. Pharm. Biopharm.54 (2002) 41–50. 10.1016/S0939-6411 (02)00036-X Search in Google Scholar Cationic polyacrylamide (CPAM) was prepared in aqueous solution by free radical polymerization of methacryloyloxy ethyl trimethylammonium chloride (DMC) and acrylamide (AM). A redox initiator system was used.
- Can cationic flocculants be synthesised by UV-induced polymerization?
- 4. Conclusions This study demonstrated facile synthesis of two cationic flocculants via UV-induced polymerization of monomers [2- (acryloyloxy)ethyl]trimethylammonium chloride and (3-acrylamidopropyl)trimethylammonium chloride for harvesting freshwater green microalgae ( C. vulgaris) and marine red microalgae ( P. purpureum ).
- Does hydrophobic association improve cationic polyacrylamide flocculation performance?
- Yang et al. successfully synthesized a cationic polyacrylamide flocculant by grafted polymerization of DMDAAC, AM, and hydrophobic monomer butylacrylate (BA); the flocculation performance of this flocculant was evidently improved because of hydrophobic association.
