Abstract

An automated system for handling core samples in and out of an imaging device retrieves the samples from a staging area. During handling, the identity of each core sample is known to the system so that the imaging results are correlated appropriately. The system positions the core sample so the vertical and slab side orientations of the core sample discernable during handling. Core samples are staged in a location, and the automated system includes a robotic arm, which senses the core sample to discern its vertical and slab slot orientations, and then loads the core sample into the imaging device. When imaging is complete, the automated system removes the core sample from the imaging device; and in designated circumstances, transfers the core sample to a location for further analysis. In one example the further analysis is based on analyzing areas of interest identified in the core sample.

Claims

1. A method of analyzing a core sample by subjecting the core sample to radiation emitted by a scan source, the method comprising:

enclosing the scan source and core sample in a cabinet to contain radiation emitted during the core sample analysis, the core sample inserted into the cabinet via a loading assembly that axially translates the core sample from a position outside of the cabinet into the cabinet, the scan source being movable within the cabinet, in an axial direction relative to the core sample, the axial direction being in the same plane as the movement of the core sample into the cabinet, wherein a core handling system installs the core sample into the loading assembly, the handling system arranged outside of the cabinet;

providing information on the core sample;

retrieving the information provided on the core sample; and

handling the core sample based on the step of retrieving the information provided on the core sample.

2. The method of claim 1, further comprising imaging the core sample.

3. The method of claim 2, wherein the core sample is maintained in a designated orientation during the step of imaging based on the information retrieved from the core sample.

4. The method of claim 2, further comprising correlating the information retrieved from the core sample with an image obtained by imaging the core sample.

5. The method of claim 2, further comprising moving the core sample to a designated location based on information obtained from the step of imaging the core sample.

6. The method of claim 5, further comprising further analyzing the core sample at the designated location with a device selected from the group consisting of a spectroscope, a laser, and combinations thereof.

7. The method of claim 6, further comprising disposing the core sample at a staging area, and wherein the step of handling the core sample comprises moving the core sample from the staging area to the core sample imaging device with the core handling system.

8. The method of claim 1, wherein the information provided on the core sample comprises the data that is selected from the group consisting of a core identifier, vertical orientation of the core sample, slab side orientation of the core sample, and combinations thereof.

9. The method of claim 1, wherein the step of handling the core sample comprises using the core handling system with an articulated arm to insert the core sample into a core sample imaging device.

10. A method of analyzing a core sample by subjecting the core sample to radiation emitted by a scan source, the method comprising:

enclosing the scan source and core sample in a cabinet to contain radiation emitted during the core sample analysis, the core sample inserted into the cabinet via a loading assembly that axially translates the core sample from a position outside of the cabinet into the cabinet, the scan source being movable within the cabinet, in an axial direction relative to the core sample, wherein a core handling system installs the core sample into the loading assembly, the handling system arranged outside of the cabinet and comprising an articulated arm to insert the core sample into the loading assembly;

providing information on the core sample;

retrieving the information provided on the core sample;

handling the core sample based on the step of retrieving the information provided on the core sample;

imaging the core sample while maintaining the core sample in a designated orientation based on the information retrieve from the core sample, the scan source moving during the imaging; and

correlating the information retrieved from the core sample with an image obtained by the imaging the core sample.

11. The method of claim 10, further comprising moving the core sample to a designated location based on information obtained from the step of imaging the core sample.

12. The method of claim 10, wherein the step of handling the core sample comprises using the core handling system to insert the core sample into a core sample imaging device.

13. The method of claim 10, further comprising disposing the core sample at a staging area, and wherein the step of handling the core sample comprises moving the core sample from the staging area to the core sample imaging device with the core handling system.

14. A system for analyzing a core sample by subjecting the core sample to radiation emitted by a scan source, the system comprising:

a mobile enclosure that seals an area around the scan source and the core sample to contain radiation emitted during analysis of the core sample, the scan source being movable in an axial direction relative to the core sample within a cabinet positioned within the mobile enclosure;

a core sample imaging device within the mobile enclosure;

a loading assembly that selectively receives the core sample and axially translates the core sample into the cabinet in the same plane as the axial direction; and

a core handling system that selectively handles the core sample between the loading assembly and a staging area, is arranged outside of the cabinet, and installs the core sample into the loading assembly.

15. The system of claim 14, wherein the core handling system comprises having an articulated arm for manipulating the core sample.

16. The system of claim 14, wherein the core handling system comprises a scanner that scan information provided on the core sample to identify the core sample.

17. The system of claim 14, wherein the core handling system maintains the core sample in a designated orientation based on information provided on the core sample.

18. The system of claim 14, wherein information about the core samples is listed on identification tags provided on the core samples.

19. The system of claim 18, wherein the information comprises the data that is selected from the group consisting of a core identifier, vertical orientation of the core sample, slab side orientation of the core sample, and combinations thereof.

20. The system of claim 14, further comprising a controller in communication with the core sample imaging device and the core handling system.
