DSGR 1 11/16 – Tracer Tool
DETAILS
The DSGR Tool measures the energy spectrum of natural gamma ray background and non-natural gamma rays occurring in the borehole and formation environment. After analyzing the recorded energy spectrum from the log, the radioactive content of the surrounding formation can be evaluated. The most typical use for this tool is to identify individual radioactive markers such as scandium (Sc), antimony (Sb), and iridium (Ir), used to tag stimulation fluids in multiple-tracer operations. With Hotwell’s proprietary software, you can determine the isotopes vertical and radial distributions, and precisely distinguish radioactive markers in the borehole from radioactive markers in the formation. The gamma ray detector is a NaI scintillation crystal (.984” ø X 5.90” L). The External temperature sensor and Casing Collar Locator are integrated in the tool.
