The Reservoir Analysis Sonde, is a multi-detector pulsed-neutron system for measuring reservoir saturation using Sigma and Carbon-Oxygen techniques. The sonde features three gamma detectors, the near and the far are high resolution Lanthanum Chloride detector for Sigma and C/O, the long spacing is a Sodium Iodide detector with a spacing that is sensitive to gas and porosity. The tool can simultaneously measure Sigma and C/O using a mixed firing pattern for the neutron generator. Reservoir Geoscience support is available to map the measurements into reservoir properties such as oil saturation, porosity and rock type.
Operating on Probe’s fast tool bus the RAS002 can be run in combination with any Probe product. As with all Probe downhole products, internal temperature is recorded to non-volatile memory to enable detailed temperature exposure records to be maintained.
