GS-NGR
NATURAL GAMMA TOOL
GS-NGR contains a longer scintillator crystal that significantly increases count rates and sensitivity. With an effective balance between sample time and counting cycle, this tool dynamically reflects gamma data at the measuring position in real time. By computing with correction factor based on specifications of borehole, drill collar, mud, etc, GS-NGR provides high-accuracy data, which places an important role in formation evaluation. This tool can be used independently or in combination with other LWD tools.
