best credit report service - The spectral gamma ray log is displayed as three curves of thorium (ppm), uranium (ppm), and potassium (%), while the gamma ray track records two gamma ray curves, the standard (SGR) and computed gamma ray (CGR). The SGR records the total gamma ray count from all sources, while the CGR results from the subtraction of the uranium contribution. The spectral gamma ray log can be used to estimate volumes and types of clay minerals, and is also useful for identifying fractures that have uranium salts precipitated in them by ground-water. Significant potassium and thorium concentrations in carbonates are also found in clay minerals and may show on porosity logs as shales. Log Presentation The total gamma ray log is usually recorded in track 1 with the caliper log, bit size and SP log. In this case, the other tracks most often include resistivity, density, neutron or sonic logs (Fig. ). Although the API scale goes from 0 to API, .
