Assignee: SAUDI ARABIAN OIL COMPANY
Field: Measurement (Instruments)
Classification: CPC G  E | IPC E  G

Claim 14:
15. A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:
obtaining, from a gamma-ray sensing system comprising a gamma-ray detector and a sensing region, first acquired gamma-ray data regarding a first core sample,
wherein the first core sample is analyzed by the gamma-ray sensing system at a plurality of periodic intervals in the sensing region using a controlled sampling motion comprising a plurality of sensor steps, and
wherein a respective sensor step among the plurality of sensor steps defines a predetermined change in distance of the first core sample in the sensing region with respect to the gamma-ray detector;

determining a sensitivity map based on the first acquired gamma-ray data and comprising a plurality of weighted coefficients, wherein a respective weighted coefficient among the plurality of weighted coefficients correspond to the respective sensor step;
obtaining, from the gamma-ray detector, second acquired gamma-ray data regarding a second core sample at the plurality of sensor steps, wherein the respective weighted coefficient determines a filtered gamma-ray signal for a portion of the second acquired gamma-ray data at the respective sensor step; and
generating a gamma-ray log using the sensitivity map and a gamma-ray inversion process.
