Figure F25. Summary of geophysical logs from the triple combination logging tool plotted vs. depth in 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; shallow, medium, and deep resistivity; sonic velocity; logging units; lithostratigraphic units; and biostratigraphic ages.
