Abstract
A measurement tool, primarily for use in a bore hole, has a neutron source located within a housing and a neutron-based detector located within the housing. At least one of the neutron source and the neutron-based detector offset from a longitudinal axis of rotation. The axially offset neutron source or neutron-based detector allow directional measurements to be made of the formations surrounding the bore hole by rotating the tool within the bore hole.
