... observed from the crude oil migration through the pore throats of reservoir formation suggesting a change in the surface properties of the reservoir rock. Furthermore, reservoir water salinity and presence of meta-aqua ions were found to promote pore blocking which further altered surface tension, thence...

... Abstract This report addresses a class of interpretation problems where formation water salinity is highly variable. In such environments, saturation equations that rely on a good knowledge of the water salinity, such as resistivity-based equations (Archie) or thermal neutron capture cross...
