This new development expands upon the Kuster® geothermal logging tool portfolio, used extensively in the global geothermal industry for its performance and reliability.

Developed to operate in hostile environments up to 325°C (617°F), the UHT Dimension tool provides two continuous independent perpendicular measurements (X and Y) of the internal diameter of the casing.  The tool also produces a high-resolution temperature profile of the well via an external fast-response resistance temperature detector (RTD).  There is no
other caliper tool that offers this versatility for ultra-high temperature and geothermal well operations.

All materials used to produce the UHT Dimension tool meet with the requisite NACE MRO175 specifications for use in corrosive wellbore environment.

 “By gathering accurate, reliable on-depth casing dimensions, geothermal companies can quantify scale build-up and any other restrictions due to the reduction in casing diameter. The tool also identifies downhole components and other anomalies.  By detecting such issues early on, the operator engaging in such proactive maintenance can maintain a critical flowrate by removing the restriction; which will aid in reducing the operational downtime and treatment cost.” said Steve Beattie, Sales Manager for Well Monitoring for Probe.

The UHT Dimension tool can be run stand-alone or combined with other Kuster® geothermal PT and PTS tools. Its robust mechanical design features single roller arms that conform easily to most wellbore conditions.
