"WebA suite of logging measurements might include spontaneous potential, gamma ray, resistivity, neutron and density curves in a single presentation. The gamma ray response (Track 1) distinguishes the low gamma ray value of sand from the higher value of shale. The spontaneous potential curve generally follows a trend similar to that of the gamma ray. " - Gamma ray measurement
