.... It is shown how such test results can be identified by the 2pMCK model and then optimally modified. In comparison with the MBC model, it is also evident that the use of Corey coefficients may at times be too prescriptive, and even flawed when it is assumed that exponents are only a function of wettability...

... wettability. Meanwhile, the energy dispersive spectroscopy was used to analyze elemental changes on the shale surface. The results showed that the contact angles of water and n-decane on the shale surface increased from 36o and 0o to 128o and 115o, respectively. The surface free energy decreased from 71 mN/m...
