Figure F24. Summary of spectral gamma-ray logs from the hostile environment natural gamma-ray sonde plotted on an expanded depth scale (mbsf) to highlight variations in the interval logged through pipe. From left to right, columns are core recovery, total gamma radiation (HSGR) and computed (uranium free) gamma radiation (HCGR), uranium, thorium, potassium, logging units, lithostratigraphic units, and bio-stratigraphic ages.
