The log under the scale on the left is the difference between the BHGM density measurements and the gamma-gamma log density measurements. The logs under the scale on the right are the density values measured by the BHGM (left line) and the gamma-gamma tools (right line). | [[:file:applying-gravity-in-petroleum-exploration_fig15-12.png|Figure 1]] shows three logs.
