Abstract
Contact angle has a major influence on the distribution of multi-phase fluids within petroleum reservoir rocks. However, there is little information on the variation of gas-oil-rock contact angle with pertinent parameters in the literature. In this study, it has been observed that the contact angle is almost constant at high gas-oil interfacial tension (IFT) above a threshold value and declines at a variable rate, depending on the volatility of the mixture, approaching zero at the critical point. The generated data were used to develop a generalized correlation between the contact angle and IFT and other measurable parameters of the system.
