Methods and systems for scan analysis of a core sample
First Claim
1. A system for analyzing a core sample of a formation, the core sample having an axis, the system comprising:
- an imaging system having a scan source and a scan receiver, positioned adjacent the core sample with at least part of the core sample between the scan source and the scan receiver, wherein the imaging system obtains one or more images of a first segment and a second segment of the core sample as the core sample moves axially between the scan source and the scan receiver; and
one or more processors for receiving the one or more images of the first segment and the second segment, setting the one or more images of the first segment adjacent to the one or more images of the second segment coaxially in series to form a three-dimensional stacked core image, and generating a plot that is aligned with a length of the three-dimensional stacked core image, the plot representing both a logged record and one or more characteristics of the core sample positioned at a corresponding location on the three-dimensional stacked core image.

Abstract
System for analyzing scan data of a core sample includes an imaging system for obtaining images of a first segment and a second segment of the core sample, and one or more processors for receiving the images of the first segment and the second segment, and setting the images of the first segment adjacent to the images of the second segment coaxially in series to form a stacked image. The method includes receiving image data of segments of the core sample, determining values representative of one or more physical characteristics of the core sample, comparing the values to known reference information of a material similar to the material of the core sample, and determining the one or more physical characteristics of the core sample based at least in part on the comparison.

8. A method for analyzing a core sample of a formation, the method comprising:
-
generating image data of one or more segments of the core sample by transmission of radiation from a scan source, across the core sample, to a scan receiver; receiving, by one or more processors, image data of one or more segments of the core sample, the image data generated by transmitting radiation from a scan source across the first segment, to a scan receiver; changing the axial position of the core sample between the scan source and the scan receiver; and transmitting radiation from the scan source across the second segment, to the scan receiver; obtaining, by an imaging system, one or more images of a first segment and a second segment of the core sample; setting, by the one or more processors, the one or more images of the first segment adjacent to the one or more images of the second segment coaxially in series to form a three-dimensional stacked core image determining, by the one or more processors, one or more values representative of one or more physical characteristics of the core sample; comparing, by the one or more processors, the one or more values to known reference information; indexing the one or more values representative of one or more characteristics of the core sample, the index being searchable for specific areas of the core sample; and determining, by the one or more processors, the one or more physical characteristics of the core sample based at least in part on the comparison. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium having computer executable instructions that when executed cause a computer to perform the operations of:
-
receiving a first image of a first segment and a second image of a second segment of a core sample of a formation, the first image and the second image generated by transmitting radiation from a scan source across the first segment, to a scan receiver; changing the axial position of the core sample between the scan source and the scan receiver; and transmitting radiation from the scan source across the second segment, to the scan receiver; aligning the first image with the second image so that adjacent images are in an azimuthal orientation with respect to one another, the azimuthal orientation matches or correlates to the azimuthal orientation of adjacent segments that are represented by the respective images, and the adjacent images form a three-dimensional stacked core image; and generating a plot that is aligned with a length of the adjacent images in the azimuthal orientation, the plot representing one or more characteristics of the core sample positioned at a corresponding location along the azimuthal orientation and a logging record. - View Dependent Claims (16, 17, 18, 19, 20)
