Paper Number: SPE-191642-MS
... functions were used for imbibition and drainage, but these functions were assumed fixed after tuning. These functions gave different values of Euler characteristic at the same value of saturation depending on the starting saturations. Their results using this approach showed good predictivity in complex...
