PHPA Mud – Adventures!
Overview: PHPA (partially hydrolized polyacriamyde) is one of the common shale stabilizer in the industry. Typically, it's the high molecular version and the molecular weight range up to 20 million :shock: How is it made? It's better to know how it was made before jump to operational practices, so we have better understanding. PHPA is…

What is Partially Hydrolyzed Polyacrylamide (PHPA
Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability.
In this work, the effect of partially hydrolyzed polyacrylamide (HPAM) on the oil–water interfacial properties of produced water from polymer flooding (PWPF) was investigated. In addition, this study investigated the effects of three fiocculants (polyaluminium chloride PAC, cationic polymer FO4800SH, and nonionic polymer 402) on the stability
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. The PHPA case we refer to a polymer of high molecular weight whose main function is likely to inhibit shale hydration.

PHPA | Partially Hydrolyzed Polyacrylamide
PHPA (Partially Hydrolyzed Polyacrylamide) Powder should be added in fresh water to get a highly viscous drilling fluid in Delhi. The marsh funnel viscosity for clay or shale formation should be ≥ 50 seconds per quart and ≥ 60 seconds per quart for sandstone or unconsolidated sand.
PHPA mud composition recommended for drilling horizontal wells had been used in this study. The reservoir rocks used were Saudi water-wet sandstone and limestone. The contact angel was used to measure the rock wettability. Also, the effect of temperature on wettability alteration had been studied.

It also exhibited low formation damage, high shale recovery, and high thermal stability than the partially hydrolyzed polyacrylamide (PHPA) polymer in the developed drilling mud system. Hence, this nanocomposite may be used as a potential drilling fluid additive in the water based drilling fluid system for shale formations.
Principal Additives of KCl Polymer Muds - Drilling Fluids
PHPA - Partially hydrolyzed polyacrylamide (PHPA) is primarily added to encapsulate solids and provide inhibition. Since PHPA purities vary from vendor to vendor, actual PHPA concentration should be ascertained to prevent over or undertreatment of the mud. PHPA is sensitive to calcium and magnesium ions.
The experimental investigations revealed that PANC exhibited superior shale encapsulation property than partially hydrolyzed polyacrylamide (PHPA). Hence, synthesized nanocomposite may be used as a drilling fluid additive in inhibitive water based drilling fluid system.
- What is poly aluminum chloride (PAC) in water treatment?
- In the realm of water treatment, various chemicals play a crucial role in ensuring the provision of clean and safe water. One such chemical is Poly Aluminum Chloride, commonly known as PAC. In this blog post, we will introduce what PAC is, its properties, applications, and its significance in water treatment processes.
- What is poly aluminum chloride (PAC)?
- Poly Aluminum Chloride (PAC) plays a significant role in water treatment by effectively removing impurities, clarifying water, and improving its overall quality. Its high coagulation efficiency, broad applicability, and low dosage requirements make it a valuable asset in the pursuit of clean and safe water.
- Who manufactures polyaluminum chloride?
- USALCO ® has manufactured chemicals for over 60 years, and began full scale production of the patented process for manufacturing Polyaluminum Chloride in 1996. Learn more about the origin of USALCO’s premier DelPAC coagulant. USALCO ® manufactures a variety of Polyaluminum Chlorides to meet a wide range of water quality objectives.
