RAS™ is the industry’s leading independent surface readout and memory capable three-detector pulsed-neutron logging tool.
Encased in a 1-11/16 in OD corrosion resistant housing, the tool measures oil, water, and gas saturation with three gamma detectors; two high-resolution Lanthanum Chloride detectors for Sigma and C/O, and one Sodium Iodide detector for gas and porosity logging. Combinable with all HD Platform tools, RAS™ can also provide added value in Well Integrity Monitoring and Production Profiling applications. As with all HD Platform tools, internal temperature is recorded to non-volatile memory to enable detailed temperature exposure records to be maintained. The neutron generator life provides the best performance in the industry, contributing toward increasing your operational efficiencies and ROI.
For your added pease of mind, Probe also offers expert training, after-sales support, and Reservoir Geoscience services. Our Petrophysics team supports our customers with data analytics across the life cycle of the reservoir from well-log evaluations to specialized statistical and analytical processes and software to map reservoir properties such as oil saturation, porosity, and rock type.
