Saturation Logging – C/O, C/H & PNN

Saturation Logging – C/O, C/H & PNN

Saturation Logging Tool (PNN)

Most widely exploited application of all pulse neutron measurements, and PNN also, is the determination of water saturation in hydrocarbon reservoirs

With the PNN system the evaluation of old wells is available for possible recompilation. PNN log provides information on:
• porosity,
• shale or clay fraction,
• hydrocarbon saturation and type

Saturation Logging Tool (RAS)

The Reservoir Analysis Sonde is a multi-detector pulsed-neutron system for measuring reservoir saturation using Sigma and Carbon-Oxygen techniques.

The tool can simultaneously measure Sigma and C/O using a mixed firing pattern for the neutron generator
