W2026810300 abstract "Abstract The adsorption of polyacrylamides on siliceous surfaces was studied by X-ray Photoelectron Spectroscopy (XPS), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and contact angle. XPS allows to determine the amount of homopolyacrylamide (PAM) adsorbed directly on mineral surface. The XPS results showed a correlation factor of 0.99 when they were compared to those obtained using the conventional technique of N-Bromination of amides. The experimental work involved in XPS determinations was found to be simple, rapid and suitable for mechanistic studies on non-consolidated rocks and sandstone cores. PAM and hydrophobic modified polyacrylamide (PAMHM) layers adsorbed on Berea discs were compared using SEM. The PAMHM polymer showed higher affinity for clay minerals and it covers the mineral surfaces with a film, largely reducing the surface roughness compared to PAM. AFM studies conducted on muscovite mica showed how the surface coverage increases with concentration of polymer. The AFM results demonstrated that hydrophobic modification of PAM increases significantly mineral coverage and attenuate surface roughness. The roughness reduction and total Berea surface coverage by PAMHM suggests an enhanced lubrication effect that could make the flow of a nonwetting fluid (oil) easier. PAMHM slighty increases surface water-wet condition as supported by additional contact angle measurements. This behavior could enhance oil recovery by improving oil mobility and reducing water mobility. The combination of these two effects, demonstrated in static adsorption tests, supports the PAMHM potential for selective permeability reduction in siliceous formations." @default.
