experimental and mechanism study: partially hydrolyzed

Experimental and mechanism study: Partially hydrolyzed

Partially hydrolyzed Polyacrylamide (PHPAM) crosslinked by Cr +3 is frequently applied to plug thief zone for the better water management in matured oil reservoir. However, PHPAM gel may certainly cause inevitable formation damage nearby the wellbore.

Partially hydrolyzed polyacrylamide: enhanced oil recovery

Although various kinds of chemical agents are reported handle PAM/HPAM degradation, it still needs a huge financial investment, and also suffers from environmental and other associated issues such as corrosion, which motivates researchers to look for other efficient and environmental friendly techniques (Khan et al., 2019).

optimization of partially hydrolyzed polyacrylamide (hpam

Optimization of Partially Hydrolyzed Polyacrylamide (HPAM

Water-soluble polymers are becoming increasingly important in various applications, such as stabilizer fluids and drilling muds. These materials are used as viscosifiers and filtration control agents, flocculants, and deflocculants due to their superior properties in increasing viscosity and gelling ability in the presence of crosslinkers. In general, studying the rheological behavior of

multiple hydrogen bonding-assisted high-strength hydrogel

Multiple Hydrogen Bonding-Assisted High-Strength Hydrogel

The nanocomposite gel system has been successfully applied as a water shutoff agent to enhance oil recovery (EOR) or for plugging to control lost circulation events. In this study, the silica/polyacrylamide nanocomposite was synthesized via in situ free radical polymerization of acrylamide (AM) monomers in the presence of silica nanoparticles. The composite was cross-linked with
