Oil recovery by waterflooding in fractured formations is often dependent on spontaneous imbibition. However, spontaneous imbibition is often insignificant in oil-wet, carbonate rocks. Sodium carbonate and anionic surfactant solutions are evaluated for enhancing oil recovery by spontaneous imbibition from oil-wet carbonate rocks. Crude-oil samples must be free of surface-active contaminants to b...

The lack of consensus on the mechanisms underpinning low salinity waterflooding (LSWF) oil recovery has affected successful implementation LSWF in carbonate reservoirs. Many investigators link improved observed from to wettability alteration. Several models are proposed literature study alteration mechanism. However, reliability some is being contested, as they struggle accurately predict trend...

Many laboratory and field scale trials have shown that modified salinity water flooding increases the mobility of oil improves recovery. However, simulation process guided by core data leads to inaccurate prediction recovery if effect saturation history reservoir on relative permeability is ignored. Here, we address this problem proposing three models illustrating interplay among wettability al...

Wettability is a pore-scale property that impacts the relative movement and distribution of fluids in porous medium. There are reservoir provoke surface within pores to undergo wettability change. This change, turn, alters dynamics permeabilities at Darcy scale. Thus, modeling impact change essential understand interaction media. In this study, we include time-dependent into permeability–satura...

Research in nanotechnology in the petroleum industry is advancing rapidly and an enormous progress in the application of nanotechnology in this area is to be expected. In particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthen...

Hydrogen can be a renewable energy carrier and is suggested to store mitigate carbon dioxide emissions. Subsurface storage of hydrogen in salt caverns, deep saline formations, depleted oil/gas reservoirs would help overcome imbalances between supply demand energy. Hydrogen, however, one the most important electron donors for many subsurface microbial processes, including methanogenesis, sulfate...
