Developments within the geophysics industry now means that instrumentation is no longer being used to calibrate and monitor the drilling process alone. Instead, tools are remaining in-situ for extended periods to monitor micro-seismic activity long after drilling has ceased. The general environmental conditions that Geochain tools are exposed to is challenging: continuous temperatures >195°C; high pressures 25000psi / 1700 bar and highly corrosive conditions combining drilling muds plus the presence of H2S/acid injection and brine. The unique combination of properties of Hiduron® 130 are exploited in the construction of the heatsink, located at the head of the tool within the pressure housing.
