Patent number: 9274245Abstract: An apparatus for estimating a property of an earth formation includes a pulsed neutron generator configured to emit a pulse of neutrons, a formation radiation detector configured to detect radiation emitted from the formation due to interactions with the pulse of neutrons, and a neutron generator radiation detector having a crystal structure and configured to detect a radiation particle emitted from the pulsed neutron generator and to provide a location within the neutron radiation detector at which the particle was detected. The crystal structure includes a plurality of detection cells, each detection cell having at least two electrically conducting columns with an applied potential difference such that electrons generated in the crystal structure by interaction with the radiation particle are collected by at least one of the electrically conducting columns to provide detection locations. A processor estimates the property using the detected formation radiation and the detection locations.Type: GrantFiled: May 30, 2014Date of Patent: March 1, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: Steven M.

Patent number: 9261624Abstract: An apparatus and method for detecting radiation in a borehole intersecting an earth formation. The apparatus may include a neutron sensitive scintillation media and at least one optically transparent neutron absorptive material optically coupled to the media, which may be positioned to prevent incident neutrons from reaching a neutron-shaded surface of the media, and to provide directional sensitivity. The neutron absorptive material may comprise a light guide optically coupled to the neutron sensitive scintillation media. The scintillation media may be disposed within the at least one optically transparent neutron absorptive material, which may be configured to prevent substantially all incident neutrons having an incident neutron energy below a selected energy threshold from reaching the media. The selected energy threshold may be approximately 0.2 eV. A neutron-reflecting material may be disposed within the scintillation media.Type: GrantFiled: June 14, 2013Date of Patent: February 16, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: Maxim Vasilyev, Toyli Anniyev, Steven M.

Patent number: 9201160Abstract: Systems, methods and devices for evaluating an earth formation intersected by a borehole. The method includes using a first radiation responsive component to detect gamma rays having an energy below a threshold energy; using a second radiation responsive component configured to detect gamma rays that traverse the first radiation responsive component; generating a reduced-Compton gamma ray spectrum by generating an anticoincidence gamma ray spectrum indicative of the gamma rays detected by the first radiation responsive component and the gamma rays detected by the second radiation responsive component. The anticoincidence gamma ray spectrum represents those gamma rays of the gamma rays detected by the second radiation responsive component that are not detected in coincidence with the gamma rays detected by the first radiation responsive component.Type: GrantFiled: November 8, 2013Date of Patent: December 1, 2015Assignee: BAKER HUGHES INCORPORATEDInventors: Maxim Vasilyev, Toyli Anniyev, Freddy E.
