Determination of radiation tracer distribution using natural gamma rays

Various apparatus or methods are arranged to operate a tool downhole in a well, where the tool has a detection package operable to detect gamma rays. Spectra peaks of the detected gamma rays can be determined in each of selected energy windows. Distribution of radiation tracer can be determined in o...

More Information
Summary:Various apparatus or methods are arranged to operate a tool downhole in a well, where the tool has a detection package operable to detect gamma rays. Spectra peaks of the detected gamma rays can be determined in each of selected energy windows. Distribution of radiation tracer can be determined in one or more regions around the tool from ratios of the spectra peaks. Additional apparatus, systems, and methods having a gamma ray detection package can operate in a variety of applications.
