Laboratory investigation of the effect of CO۲ and gaseous hydrocarbons on the wettability of real samples

Wettability is one of the properties of reservoir rocks that connects the rock part and the fluid inside the formation. If the rock tends to absorb water, it is considered water-wet (hydrophil), and if it tends to absorb oil, it is considered oil-wet (hydrophob). In this article, the main goal is to investigate the effect of CO۲ gas and Forouzan oil field gas on the equilibrium samples consisting of sand and oil from the Soroush oil field
