Geothermal PTS & CCL

Dewar flask insulated downhole electronics for geothermal pressure temperature flow and casing collar locator measurements.

For use in temperatures up to 300°C (600°F) and pressures up 30 000 psi.
A geothermal tool has a large Dewar flask housing that insulates the internal, temperature sensitive components. As well as the insulating housing, the tool assembly has a large internal heat sink assembly. The insulation, and the internal heat sink work together to prevent and absorb heat energy. This allows the internal electronics to stay below their critical operating temperatures.

A geothermal tool has a large Dewar flask housing that insulates the internal, temperature sensitive components. As well as the insulating housing, the tool assembly has a large internal heat sink assembly. The insulation, and the internal heat sink work together to prevent and absorb heat energy. This allows the internal electronics to stay below their critical operating temperatures.

The following graph illustrates the geothermal tools performance at different external temperatures.
