The standard DTN38 probe provides long-(LSN) and short-spaced(SSN) 4π thermal
Since the probe reacts strongly to hydrogen content, the principal application
of this method is for formation water content (porosity) measurement. As an
option (highly recommended), the probe can be supplied with a natural gamma
detector to permit the influence of clay content on the results to be evaluated.
Useful when the probe is deployed for through-tubing oil/water/air contact
measurements, a casing collar locator (CCL) detector is also available as a
factory-fitted option for this probe.
