Directional radiation detection tool

摘要

Various systems and methods for implementing a directional radiation detection tool are disclosed. One such method involves receiving outputs from several radiation sensors (e.g., gamma ray sensors), which are each facing a different direction. The received outputs are then combined, such that a directional error in one of the outputs is reduced, based upon another one of the outputs.

主权项

1. A method comprising:
receiving a first output from a first radiation sensor and a second output from a second radiation sensor, wherein the first output and the second output are generated while the first radiation sensor and the second radiation sensor are within a wellbore into a formation, wherein the first output indicates a location of a radioactive source within the formation, and wherein a window in the first radiation sensor faces a different direction than a window in the second radiation sensor; and combining the first output and the second output, wherein the combining reduces a directional error in the first output's ability to indicate the location of the radioactive source, based upon the second output.
