Extreme logging environments? No problem!

The Xtreme high-pressure, high-temperature logging platform integrates technologies rated to 500 degF and 25,000 psi into one rugged, efficient toolstring.

Accurate resistivity, formation density, neutron porosity, and sonic measurements are available in real time, fully corrected for borehole and environmental effects.

The NGS natural gamma ray spectrometry tool can be combined with the Xtreme platform for additional formation evaluation insight.

The quad-combo dataset logged by the Xtreme HPHT logging platform provides the minimum information required for basic formation evaluation answers, such as porosity and saturations.

This foundational insight is readily expanded by combining the dataset from the Xtreme platform with additional measurements. Integrated interpretation employs advanced workflows, the multidisciplinary expertise of our interpretation geoscientists and engineers working with you as needed, and software such as the Techlog wellbore software platform to maximize the value of your logging data. The result is the fullest possible understanding of complex lithologies, such as carbonate, shaly sand, and shale reservoirs.
