New Insight into Wettability Alteration to Gas Wetness: Core Experiment and Modeling

Abstract:

Many attentions have been paid on wettability alteration to gas wetness since it is widely concerned in 2000. Although many researchers tried to explain or realize such phenomenon, several problems have not been resolved now including possibility and mechanism of wettability alteration in water saturated cores. In this study, new insight is made into wettability alteration to gas wetness, both experimental and simulate. A serial of spontaneous water imbibition experiments are conducted to evaluate applicability of wattability alteration in different water saturated cores. SEM observation indicates microcosmic mechanism by compare of pore surface before and after chemical treatment. Numerical simulation in Eclipse gives theoretical evidence of wettability alteration phenomenon and also proves almost the same result with that in spontaneous water imbibition experiments.
