Figure 35. Example of generalized lithology logging with Combination Gamma Ray Neutron-Density Log. This figure shows
sample relationships between log responses and the rock type. and also shows changes in the log response from oll- or
water-bearing rock units compared to gas-bearing units.
This briefly shows how the Combination Gamma Ray Neutron-Density Log is used as a tool for determining lithology.
