Figure F34. Summary of geophysical logs from the triple combination logging tool, plotted vs. depth for the open-hole logged interval. The data, plotted from left to right, are core recovery; caliper and total gamma radiation (HSGR); porosity and density, scaled so that the two curves will coincide for a clean limestone; photoelectric effect (PEF); shallow, medium, and deep resistivity; sonic velocity; logging units; lithostratigraphic units; and biostratigraphic ages.
