Low permeability oil and gas resources are rich and have great potential all over the world,
which has gradually become the main goal of oil and gas development. However, after …

The application of surfactants in enhanced oil recovery (EOR) processes aids in reducing
interfacial tension at the oil-aqueous interface as well as altering the wetting nature of the …

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 …

This study compared the potential applications of xanthan gum and hydrolyzed
polyacrylamide (HPAM) as polymer-flooding agents for heavy oil recovery applications …

Polymer flooding is an enhanced oil recovery (EOR) method used to increase oil recovery
from oil reservoirs beyond primary and secondary recovery. Although it is one of the most …

Water-soluble polymers are known to be used in chemically enhanced oil recovery (EOR)
processes, but their applications are limited in high-temperature and high-salinity oil …

This paper studied the strengthening effects of silica nanoparticles on the polyacrylamide
(PAM)/hydroquinone (HQ)–hexamethylenetetramine (HMTA) composite gel. Pure PAM/HQ …

Today, hydrogel plugs as a new and effective technology are widely used for temporary oil
and gas well plugging. Although, the strength and fluidity of the hydrogels in the oil wells …

Our objective in this study is to fabricate a novel chitosan-based ternary nanocomposite
hydrogel film by incorporating graphene oxide (GO) nanosheets into a chitosan/partially …

The current study aims at in-depth profile control to further improve oil recovery by studying
the matching relationship between the size of dispersed particle gel (DPG) and geometry of …
