contact logging device
A device that consists of a spring bow very analogous to a section gage. On one arm of the bow is a rubber pad shaped to fit the curvature of the hole. In this pad, slightly recessed, are three electrodes of about diameter 1/2 in (1.3 cm) and located at 1-in (2.54- cm) intervals. These three electrodes are used to record two resistivity curves. One curve is a three-electrode type with a spacing of 1-1/2 in (3.8 cm), and the second is a twoelectrode type with a spacing of 2 in.
