Polymer Treatment for Water Control in High-Temperature
A polymer treatment based on the use of a nonionic high-molecular-weight polysaccharide has been proposed for water control in high-temperature production wells. This polymer has excellent viscosifying power in all types of reservoir brines, high shear resistance and good thermal stability.
Polyacrylamide (PAM) use in irrigation for erosion control has increased water infiltration and reduced soil erosion. This has improved runoff water quality via lower concentrations of nitrogen

3. Summary Polyacrylamide polymer gels have made a significant im- pact on shut-off and profile control treatments, the sealing of open wellbores, abandonment of zones or wells, and so on. The development of preformed particle gels is a promising direction in polymer gel treatments since these gels overcome several in-situ gel inherent problems.
Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
The chemical polyacrylamide (PAM) is well suited for erosion control enhancement, and its use is described below. In the mixing tank, the powder is slowly introduced into the water under constant, heavy agitation be sure all runoff passes through a sediment control feature, such as .

Modeling of Partially Hydrolyzed Polyacrylamide-Hexamine
The cross-linked polymer gel systems are being used increasingly to redirect or modify reservoir fluid movement in the vicinity of injection wells for the purpose of permeability/profile modification job in the oil field due to their high temperature stability and capability to provide rigid gel having high mechanical strength. In this study, a partially hydrolyzed polyacrylamide-hexamine
found to be effective in water shut-off jobs during oil production. Relative permeability modifiers in water shut-off jobs/Improved oil recovery Polyacrylamide gels Polyacrylamide gels have been used to reduce water cut in production wells and control profiles in injectors. Formations up to 66°C have been treated rather routinely.

- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- What is organic polymer flocculant cationic polyacrylamide (CPAM)?
- The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [ 11, 12, 13, 14, 15 ].
