ABSTRACT:
In a subsurface formation, where shaliness affects the results of typical electrical well logging measurements, partial water and partial hydrocarbon saturations are determined from measurements of dielectric constant. The relation between dielectric constant and conductivity due to shaliness in a partially water saturated formation and a relation defining dielectric constant change as a function of partial water saturation are used to determine partial water saturation and partial hydrocarbon saturation of said formation.
