|Towards better borehole logs||A paper presented at the SAGA 2015 conference held in South Africa, September '15. The paper discusses a new approach to correcting spectral gamma data taken in boreholes. It is our aim to arrive at a worldwide interconnected series of calibration pits for spectral gamma borehole tools allowing proper inter comparison of data.||2015|
Towards a global network of gamma-ray detector
Gamma-ray logging tools are applied worldwide. At various locations, calibration facilities are used to calibrate these gamma-ray logging systems. Several attempts have been made to cross-correlate well known calibration pits, but this cross-correlation does not include calibration facilities in Europe or private company calibration facilities. Our aim is to set-up a framework that gives the possibility to interlink all calibration facilities worldwide by using ‘tools of opportunity’–tools that have been calibrated in different calibration facilities, whether this usage was on a coordinated basis or by coincidence.
