Abstract

A complex 64-in. normal log from the 3,249-m-deep Rattlesnake Hills well was digitized and reduced to a form resembling a simple resistance log. The simplified form of the log made it possible to recognize three major geoelectric intervals in the well that were not apparent on the original log. The apparent resistivity values from each geoelectric interval are grouped into a frequency-distribution table, where midpoints of the class interval are corrected for the effects of hole diameter and mud resistivity. Using corrected class-interval midpoint resistivities, first-approximation values are calculated for five geoelectric parameters: total transverse resistance, total longitudinal conductance, average longitudinal resistivity, average transverse resistivity, and the coefficient of anisotropy. Comparison of anisotropies, resistivity variations, and resistivity-frequency polygon shapes indicates quantitative differences among the three geoelectric intervals.
