Adsorption behavior of the polymeric systems based on sulfonated polyacrylamide/scleroglucan on carbonate reservoir particles

Adsorption of chemicals such as polymers, surfactants, nanoparticles is important in enhanced oil recovery process. The objective of the present study is to investigate the adsorption behavior of sulfonated polyacrylamide (SPA)/scleroglucan (SC) systems on calcite particles with a focus on enhanced oil recovery applications. The results show that the increase of salinity had no significant effect on the adsorption of pure SPA, but decrease the adsorption of SC polymer on calcite. It is found that the adsorption of crosslinked SPA/SC polymeric system is significantly greater than adsorption of pure SC or pure SPA, making it a prospective candidate for heterogeneous oil reservoirs
