...G.R. Pickett The basic saturation and log response equations are reviewed. It is concluded that conventional saturation calculations account for lithology and rock-type changes, but that they are susceptible to uncertainties in water resistivity (Rw), true resistivity, porosity and cementation...

...A.W. Talash An equation has been developed for calculating water resistivities from chemical analyses. This equation provides a means of obtaining resistivities of formation waters directly from chemical analyses without the aid of tables, conversion factors or resistivity vs concentration plots...

... for the success- ful use of this logging combination are: 1. The formation must be invaded by mud filtrate. 2. The ratio of mud filtrate resistivity to formation water resistivity must be known and the ratio should not exceed 10. 3. The mud filtrate resistivity must be known. When there is very shallow...
