Abstract

Logging tools include at least one neutron source, at least one neutron detector positioned a prescribed distance from the neutron source, and at least one processing/analyzing unit or subsystem, where the detectors include a gas chamber having a voltage drift region and containing a gas mixtures capable of interacting with fast neutrons to produce detectable events that are imaged by an imaging subsystem and interpreted by an analyzing subsystem and systems and methods using the tools. The tools may be disposed on a wire line or integrated into a drill string so that logging may be performed while drilling.
