Figure 1

A schematic view of the simulated logging device in the borehole. The device includes a 137Cs gamma source and two NaI detectors. The Pb shield is placed between the source and the near detector to avoid detecting the directly arrived gamma rays. The formation encircles the borehole. This graph, as well as those in Figs. 2 and 3, have been drawn by LibreOffice 6.3.4, https://www.libreoffice.org/download/download/?type=deb-x86_64amp;version=6.3.4amp;lang=en-US.
