... law becomes invalid and any estimate of water saturation using Archie's equation will most likely yield erroneous results. Many scholars and researchers have attempted to come up with models linking well logs and laboratory data to estimate water saturation in complex pore systems. To appropriately...

... interaction properties, using contact angle measurements on both sandstone and carbonate model surfaces. Furthermore, we investigated the effect of the additive on the capillary pressure properties and remaining water saturations on sandstone and carbonate rocks. To maximize the generality of the results we...

... Abstract Petrophysical models are used to estimate formation water saturation and salinity from dielectric dispersion data. These models are sensitive to other attributes of the formation such as wettability. Previous studies, analyzing different parameters of dielectric petrophysical models...
