Open Hole Logging

Included in our product & service offering is a full set of combinable Open Hole tools rated to oilfield specifications (165 °C, 20,000 psi).


We also offer an extensive selection of smaller diameter tools with lower temperature and pressure ratings. These tools are ideally suited for cost effective CSG logging operations and mineral, geotechnical, environmental and groundwater applications.


Many of the small diameter services have combined sensors that reduce the number of logging runs required to obtain a comprehensive set of formation evaluation data.
