FIG. 8.1 Raw logs, inverted logs, and target NMR T2 distribution logs acquired in the 300-ft depth
interval of a shale formation. Track 1, formation tops; track 2, gamma ray; track 3, resistivity; track
4, density and neutron porosity; track 5, sonic travel times; track 6, mineral contents and fluid
saturations; and track 7, NMR T2 distribution.
