Intrinsic germanium gamma-ray data from the New American Petroleum Institute spectral gamma-ray calibration models
High-resolution gamma-ray spectra have been recorded at the new American Petroleum Institute (API) spectral gamma-ray logging calibration center with a US Department of Energy passive spectral gamma-ray logging unit. These measurements were completed before gamma-ray source concentrations were assigned to the calibration model zones. Analyses of spectra gathered from five of the calibration zones yielded linear relationships between: (1) tentative uranium concentrations and intensities of the 352-, 609-, and 1,764- keV gamma-ray peaks, and (2) tentative thorium concentrations and intensities of the 583-, 911-, and 2,615-keV gamma-ray peaks. The tentative potassium concentration and associated 1,461-keV gamma-ray peak intensity for the High Mix zone did not conform to the linear function defined by the tentative concentrations and peak intensities for the four other zones. The function implied that the peak intensity for the High Mix zone corresponded to a potassium concentration of about 4.05%. This was substantially smaller than the tentative value of 5.62%. A slightly different analysis led an API spectral gamma-ray calibration task group to concentrations of 3.98 {plus minus} 0.26% for the High Mix zone and 0.90 {plus minus} 0.12% for the Low Mix zone. The task group has recommended that the API assign these concentrations to the zones.
