High Pressure, High Temperature

High-precision measurements for the extremes of HPHT environments

High-pressure, high-temperature (HPHT) conditions are no longer a barrier to integrated wireline logging services. Our innovative technology makes possible high-precision measurements that are recognized as industry benchmarks for extreme environments.

Ruggedized designs and extended qualification testing result in HPHT tools that perform reliably and efficiently to minimize risk in even the most challenging operations—remote exploration, deep water, drillpipe conveyance, and harsh conditions.


Make fast, accurate pressure and mobility measurements in high-temperature environments.


Break through the logging barriers of high-pressure, high-temperature ultradeep wells as small as 3 7/8 in.
