Partially Hydrolyzed Polyacrylamide (PHPA) Mud Systems
For exploration and development drilling of deepwater prospects in the Gulf of Mexico, operators have primarily utilized a high salt (20 percent w/w), partially hydrolyzed polyacrylamide (PHPA) mud system. This system has been used for many years as one of the most inhibitive water-based mud systems commercially available to the industry.
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.
PHPA Partial hydrolyzed polyacrylamide
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.
Partially Hydrolyzed Polyacrylamide (HPAM) in act with water after polymer flooding in oil filed reasons in environmental troubles, such as enhancement in the oil-water detachment trouble, natural degradation to make toxic acrylamide and jeopardize local ecosystem. Bio-degradation of HPAM may be a cost-efficient mode for solving these problems.

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
phpa powder Acuro's PHPA Powder is a synthetic co-polymer of anionic nature and high molecular weight, which is used in drilling of mud systems ranging from low solids to weighted muds. The cost-effective completion of Oil-drilling projects is largely dependent on the quality of its fluid systems.

- What are Ozonia containerized ozone water treatment systems?
- Ozonia containerized ozone water treatment systems have the same outstanding features as Ozonia products and engineered systems. Containerized ozone plants are capable of producing ozone at very high concentrations from either oxygen or air feed gas. Although designed and built to minimize capital costs, we never compromise on quality.
- What is ozone water treatment?
- Ozone is one of the most power oxidation tools water treatment professionals have for purification and disinfection. Veolia has been the ozone water treatment industry pioneer for decades. We design and manufacture a complete range of Ozonia ozone generators from laboratory products to the largest ozone water treatment systems in the world.
- Who uses professional ozone generators?
- Professional ozone generators are utilised by professional farmers, public swimming pools, drinking water, process water, wastewater, laboratories, research facilities, cooling towers, and other applications. Compact ozone generation plants for water treatment. With productions of up to 150gO 3 /h and a high concentration of ozone.
- What are ozone systems used for?
- Ozone system to disinfect industrial process waters as cooling towers; osmotized, distilled, and ultra-pure water tanks; fruit washers; bottling plants; CIP... See available treatments We have 10 years of experience in ozone solutions for agriculture.
