Description
The Spectral Gamma Ray & Casing Collar Locator Tool (SGRCL2) operates on our common tool bus and can be combined with the Reservoir Analysis Sonde, Production Logging Tools or both.
The SGRCL2 consist of a Casing Collar Locator sensor (CCL) signal and a Sodium Iodide gamma-ray detector and electronics. The tool outputs are total GR counts, a 256 channel spectrum of gamma ray energy and the CCL signal. Processing on the surface system analyses the gamma ray spectrum for the three most common natural radioisotopes: potassium (K), uranium (U) and thorium (Th).
Data from the SGR processing is used for mineral composition and Clay Volume calculations. The tool may also be used for isotope identification during fracturing operations and may provide useful insight to RA deposits in and around the wellbore.
