ABSTRACT:
The present apparatus and method are directed to a high frequency dielectric measurement system for use in logging a well borehole. A transmitter transducer cooperative with one or more receiver transducers arranged on a common pad is utilized to make such measurements. Typically they occur in the gigahertz range. One feature of the present disclosure is the indication of the apparent water filled porosity of formations. Another feature relates to the formation of a quality curve obtained by breaking down the formation measurements into real and reactive components.
