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.
Partially hydrolyzed polyacrylamide (HPAM) in production water after polymer flooding in oil filed causes environmental problems, such as increases the difficulty in oil–water separation, degrades naturally to produce toxic acrylamide and endanger local ecosystem. Biodegradation of HPAM may be an efficient way to solve these problems.

Polyacrylamide
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
2.2. Polyacrylamide (PAM) gel system. PAM gel is the most prevalent gel system that has been applied in the fields to enhance oil recovery. PAM gels are mainly used as permeability reducers to block the high permeability zones and divert the water or CO 2 to the low permeability zones to improve sweep efficiency hence to improve oil recovery
Polyacrylamide gel polymer as water shut-off system
Polyacrylamide (PAM) and partially hydrolysed polyacrylamide (HPAM) are the most used water soluble polymers in Enhanced Oil Recovery (EOR) applications because they represent a powerful means of
PAM (Polyacrylamide) with its high molecular weight (> 1.0 × 10 6 g/mol) was the first thickening agent used for aqueous solutions. PAM is stable up to 90°C at normal salinity and up to 62°C at seawater salinity. Therefore, it is somewhat restricted to on-shore operations only. [5]

Polymeric gels are used to reduce or shut off excess water in petroleum reservoirs. The strength of polymeric gels needs to be high enough to withstand the water flow. This study investigates the strength of an organically crosslinked polyacrylamide (PAM) with polyethylenimine (PEI) as crosslinker.
- Which cationic polyacrylamide has a charge density of 40%?
- Three commercial cationic (PAM +S,τ40 ), nonionic (PAM °S) and anionic (PAM −S,τ40) polyacrylamides (PAMs) with a medium chain length produced by the SNF group (Andrézieux, France) were used ( Table 1 ). PAM +S,τ40 and PAM −S,τ40 have a charge density of 40%.
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- Are cationic and anionic polymers the same?
- Both anionic and cationic polymer forms are known; however, the bulk of commercially successful products are cationic. These products are useful particularly in papermaking applications where the presence of oils and surfactants are environmentally unfriendly or are detrimental to the papermaking process. 34.2.5.3.
