Probe’s range of industry-leading cased-hole formation evaluation tools include the RAS™ (Reservoir Analysis Sonde), a 3 detector Pulsed Neutron tool, Spectral Gamma Ray as well as other tools such as Gamma Ray and Compensated Neutron to enable advanced reservoir evaluation in mature fields or new well completions.
The cased-hole formation evaluation (FE) solutions suite is a group of cutting-edge cased-hole logging tools that provide comprehensive data to drive reservoir performance. The suite is extremely versatile, and includes the Reservoir Analysis Sonde (RAS™), a pulsed-neutron tool that can be combined with production logging and well integrity tools to deliver just the right data for your objectives. The tools in the suite operate in either memory or surface-readout mode and can be conveyed using wireline, slickline, or tubing.
