Partially hydrolyzed polyacrylamide: enhanced oil recovery

Research on the mechanisms of polyacrylamide nanospheres with di?erent size distributions in enhanced oil recovery Shuo Wang,a Zhongli Tang,b Jin Qu,a Tongbo Wu,b Yuxing Liu,a Jing Wang,a Xiaofei Liu, *a Ye Juc and Fenggang Liuc Crosslinked polyacrylamide microspheres are widely used as in-depth ?ooding agents in petroleum

When 0.5 PV of polymer nanospheres at 5000 mg L ?1 was injected, the oil recovery of the high permeability tube was enhanced by 24.38%, while the oil recovery of the low permeability tube was enhanced by 23.09%. This indicated that the polymer nanospheres could plug the high permeability tube, reduce its permeability, and change the direction

Enhanced Oil Recovery Using Micron-Size Polyacrylamide

One of the most important use of polyacrylamide is in subsurface applications such as enhanced oil recovery (polymer flooding), where high viscosity aqueous solutions are injected to improve the economics of conventional water flooding.

Rheological Properties of Partially Hydrolyzed Polyacrylamide

This work aims to improve the rheological properties of partially hydrolyzed polyacrylamide (HPAM) for enhanced oil recovery by using silica (or silicon dioxide, SiO2) nanoparticles (NPs). Novel aqueous HPAM-based SiO2 nanocomposites were formulated, and their rheological properties were investigated under different salinities, temperatures, and aging times. The results show that the inclusion
