ELPASOLITE SCINTILLATOR-BASED NEUTRON DETECTOR FOR OILFIELD APPLICATIONS
First Claim
Patent Images
1. A borehole logging tool comprising:
- a neutron source for releasing source neutrons toward a target formation; and
a scintillator positioned to interact with scattered source neutrons received from the target formation, the scintillator configured to emit luminescence in response to interaction with at least one of thermal and epithermal neutrons, wherein the scintillator comprises an elpasolite material.

Abstract
Embodiments described herein are directed to methods and neutron detectors for use in downhole and other oilfield applications. In particular, the neutron detector includes a scintillator formed at least partially from an elpasolite material. In a more specific embodiment, the scintillator is formed from a Cs2LiYCl6 (“CLYC”) material.

14. A method for detecting neutrons, the method comprising:
-
positioning at least one scintillator comprising an elpasolite material in a well borehole; releasing neutrons into a formation proximate to a region of the well borehole; detecting luminescence from the scintillator, wherein the scintillator emits luminescence in response to interaction with neutrons returned from the formation; and converting luminescence from the scintillator to an electrical signal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
