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

شیمی 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 ...
