A computer program for calculating the direct current resistivity response for electrodes buried in a horizontally stratified earth

A listing of a computer program to calculate the direct current resistivity response for electrodes buried within a horizontally layered earth is presented. The program is designed to calculate the response for the following electrode configurations: (1) hole-to-hole fixed source; (2) hole-to-hole moving source; (3) hole-to-hole surface with a fixed borehole source and a surface bipole receiver; (4) normal well logging array; (5) dipole-dipole well logging array; and (6) lateral well logging array. Examples are given for each of these arrays.
