The GCL is a combined Gamma Ray & Casing Collar Locator tool which provides a passive measurement of gamma radiation by means of a Sodium Iodide Scintillation Detector and identifies of changes metal thickness by means of a collar locator.
High voltage to the PMT is adjusted with temperature to maintain sensitivity over the whole temperature range.
As with all Hunter Well Science downhole products, internal temperature is recorded to non-volatile memory to enable detailed temperature exposure records to be maintained.
