Shale and Clay Stabilizers - Baroid
QUIK MUD® D-50 liquid polymer dispersion is a high-solids, partially-hydrolyzed polyacrylamide/polyacrylate (PHPA) copolymer used primarily as a viscosifier and borehole stabilizer to prevent reactive shale and clay from swelling and sloughing. QUIK MUD® GOLD Clay/Shale Stabilizer
PHPA-L is an emulsion of a high molecular weight partially hydrolyzed polyacrylamide polymer (PHPA) in mineral oil. POLYCAP: POLYCAP is a highly cationic liquid polyamine used in water based drilling fluids as a shale inhibitor and stabilizer. It is effectively resistant to high temperature and salt. Potassium Asphalt Sulfonate
Partially Hydrolyzed Polyacrylamide (Liquid) | EBIC
Partially Hydrolyzed Polyacrylamide (Liquid) is a liquid emulsion of acrylic co-polymers designed to improve performance of all types water based mud systems (WBM), which imparts shale and bore-hole stability, viscosity modification, lubricity, selective flocculation and assists with fluid loss control. Partially Hydrolyzed Polyacrylamide (Liquid) provides a cost effective means of controlling drilling fluid characteristics and improving performance in a wide variety of fluid environments.
This is partially hydrolyzed polyacrylamide (PHPA), which is suitably modified to meet the specification for use in drilling fluids. SIR-COAT is equivalent to the product such as a Redi-coat of Messina, New Drill of Milpark and EZ-Mud of Baroid, Poly Plus of MI.
Borehole, Shale Stabilizers - Halliburton
Borehole, Shale Stabilizers Drilling practices and the physical & chemical properties of drilling fluids can either enhance or erode borehole stability. Our borehole stabilizers serve as "preventive medicines" that help operators avoid the difficult and expensive tasks associated with remediating an unstable formation.
Partially hydrolyzed polyacrylamide (PHPA) is a copolymer, substance formed when two or more substances are polymerized simultaneously, resulting in a product that is not a mixture of individual polymers, but a complex which has different properties from each polymer by separated. The PHPA case we refer to a polymer of high molecular weight whose main function is likely to inhibit shale hydration.

The partially hydrolyzed polyacrylamide works by reducing the fluid mobility through increasing the viscosity or reducing permeability of the oil recovery drive fluid. With this process, the polymer acts as a fluid flow blocking agent. Apart from oilfield application, this polymer is also popularly used in flood areas to restrict water flow

POLY-BORE stabilizing agent is a very high molecular weight partially hydrolyzed polyacrylamide (PHPA) polymer. When mixed with fresh water, a small quantity of POLY-BORE stabilizing agent can provide a clear, solid-free, viscous borehole stabilizing fluid for use in drilled shaft, auger drilling, horizontal directional boring, trenching
Partially Hydrolyzed Polyacrylamide PHPA. Shale Inhibitor / Viscosifier / Flocculant. is a readily dispersible additive designed to provide cuttings encapsulation and shale stabilization in freshwater to saltwater drilling fluids ranging from low solids to weighted muds. stabilizers and bottom hole assembly by coating and lubricating
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- Is PHPA a water soluble polymer?
- Description: PHPA is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems.
- What is polyacrylamide?
- Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
- Which comonomer is used for the production of anionic polyacrylamides?
- The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
