Experimental Investigation of the effect ions concentration, aging temperature and pH on Wettability alteration Process in Carbonate Rocks by Contact Angle Measurement [PDF]

open access: yesشیمی کاربردی روز, 2013
Naturally fractured carbonate reservoirs have very low oil recovery efficiency owing to their wettability and tightness of matrix. Recovery efficiency can be considerably improved by changing reservoir rock wettability from oil-wetting to water-wetting ...

Surfactant-Induced Wettability Alteration

open access: yesScientific Contributions Oil and Gas, 2022
Contact of surfactant solution onto rock surface has an important impact on the wettability alteration of the rock. This phenomenon has widely received attention of researchers on the field of EOR (enhanced oil recovery), at which surfactant solution basically has been used as the main injection fluid. However, there has not yet come up with conclusive

Numerical study of low salinity water flooding for enhancing oil recovery in sandstone reservoirs by coupling fluid flow equations with geochemical reactions of ion exchange and calcite dissolution [PDF]

open access: yesمجله مدل سازی در مهندسی, 2019
Low salinity water (LSW) flooding is one of the emerging EOR methods which has recently attracted lots of attention. Wettability alteration from oil-wet to water-wet triggered by ion exchange between low salinity water and rock surface is one of the ...
