Pulsed neutron

READ’s Pulsed Neutron tool, the Reservoir Analysis System (RAS), is a state of the art, multi‑detector pulsed‑neutron tool designed 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 for Sigma and C/O, the long spacing is a Sodium Iodide detector with a spacing that is sensitive to gas and porosity. It can simultaneously measure Sigma and C/O using a mixed firing pattern for the neutron generator.
