Description
The FDT utilizes a double encapsulated low energy AM241 source and scintillation detector assembly to measure fluid density in the measurement window of the tool.
This measurement is unaffected by well deviation or fluid velocity making it suitable for deployment in a very wide range of environments. The FDT is a short, robust and reliable tool, easily maintained and well suited to e-line SRO operations or Memory operations on Slickline, Coil Tubing or Tractor.
High voltage to the PMT is adjusted with temperature to maintain sensitivity over the whole temperature range.
The tool uses a dual channel receiver. The 2nd channel counts high energy gamma rays from scale or formation which correct the main channel.
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.
Applications / Features
- Low energy, double encapsulated, AM241 source, Collimated design
- Shielded detector assembly
