Description
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.
Features
- Lithology determination
- Depth correlation
- GR detector for downflow Oxygen Activation logging when run below RAS
- RA scale identification
- Simple tracer monitoring
- SRO or Memory Operation
- Plug in electronics are used throughout enabling local upgrade and repair.
