ABSTRACT:
In the logging of a grade characteristic of a borehole core, the core is placed in a trough which is caused to move, in step fashion, through an annular detector. For each step the detector measures a characteristic of a notional segment of the core. The measures are corrected to compensate for contributions due to adjacent notional segments. The correction factor is derived by passing a core segment of known characteristics through the detector under controlled conditions.
