Figure 4

Average values of various characteristics of gas bearing mudstones in Shanxi formation of four wells. Response characteristics from logging data (a). Mineral characteristics (b), geophysical and geochemical characteristics (c) from core measurements. Where GR is the natural gamma ray, RT is the deep lateral resistivity, AC is the acoustic transit time, DEN is the density, CNL is the neutron, K is the potassium, TH is the thorium, U is the uranium, H is the thickness, TOC is the total organic carbon content, and Ro is the vitrinite reflectance.
