Figure F38. Depth shifting of downhole logging data. A. Hole shape. B. Total natural gamma radiation HSGR_m from the Hostile Environment Natural Gamma Ray Sonde tool on the main pass of the triple combo tool string and multisensor track (MST) natural gamma radiation (NGR) measured on whole cores. The core data were used as reference for depth shifting. C. Total gamma radiation HSGR_r from the repeat log plotted along with HSGR_m. D. Total gamma radiation (GR) from the Multi-Sensor Gamma Ray Tool (MGT) log with respect to HSGR_m. E. Hole shape measured by the FMS-sonic calipers. F. Computed gamma ray (ECGR) from the SGT tool on the FMS-sonic tool string plotted along with the total gamma radiation (HSGR_m) from the HNGS main run on the triple combo. G, H. Combined plot of HSGR_m, HSGR_r, GR, and ECGR, including close-up, showing the good depth and pattern matching between the natural gamma ray logs of the different runs.
