Core sample preparation, analysis, and virtual presentation
View Patent ↗Core samples may be easily, quickly, and safely split using a fluid cutter, such as a water jet. Cutting may take place upon exit of the sample from the drill tube, or core samples may be placed in core carriers for cutting. Core samples may also be stored and transported in the core carriers. Assessment of core samples is facilitated by scanning the core samples, with the results stored to produce a virtual core sample. Virtual core samples may be displayed on a computing device, including a core sample display device which simulates the appearance of a section of an actual core.
1. A method of operating a core processing apparatus, the method comprising:
causing the core processing apparatus to:
extract a core sample;
perform a first scan of the core sample;
after performing the first scan of the core sample, cut the core sample along a longest dimension of the core sample using a fluid jet; and
after cutting at least a portion of the core sample, perform a second scan of the cut core sample.
2. The method of claim 1 , further comprising causing the core processing apparatus to extract the core sample from a core tube, wherein the cutting occurs during the extracting.
3. The method of claim 1 , further comprising causing the core processing apparatus to place at least a portion of the core sample into a carrier.
4. The method of claim 1 , wherein the fluid jet comprises a water jet with abrasive.
5. The method of claim 1 , further comprising causing the core processing apparatus to calibrate assay results based at least in part upon an analysis of contamination from the fluid jet.
6. The method of claim 1 , wherein the fluid jet comprises carbon dioxide in a solid state.
7. The method of claim 1 , further comprising causing the core processing apparatus to store resulting scan data in a computer readable storage medium.
8. The method of claim 7 , wherein performing the first scan and performing the second scan comprises at least one of:
imaging the core sample with a camera;
imaging the core sample with visual light;
imaging the core sample with ultraviolet light;
sensing a magnetic field; or
detecting an X-ray fluorescence.
9. An apparatus comprising:
a pre-cut scanning assembly configured to perform a first scan of at least a portion of a core sample;
a fluid cutter configured to cut at least a portion of the core sample;
a post-cut scanning assembly configured to perform a second scan of at least a portion of the core sample; and
a carrier configured to hold at least a portion of the core sample during cutting.
10. The apparatus of claim 9 , wherein the carrier comprises:
a base having an exit aperture for fluid exhaust; and
a removable or moveable top cover having an entrance aperture for a fluid stream from the fluid cutter.
11. The apparatus of claim 9 , wherein:
the post-cut scanning assembly comprises one or more sensors configured to perform the second scan; and
the second scan includes scanning at least an interior portion of the core sample.
12. The apparatus of claim 11 , wherein the pre-cut scanning assembly and the post-cut scanning assembly comprise a single scanning assembly.
13. The apparatus of claim 11 , further comprising a computer readable storage device configured to receive and store data from the one or more sensors.
14. The apparatus of claim 9 , further comprising a marking assembly configured to place one or more marking indicia on the core sample, the carrier, or both.
15. The apparatus of claim 14 , wherein each of the marking indicia correspond to a linear position of the core sample.
16. A method of operating a contiguous system comprising:
causing the contiguous system to:
extract a core sample;
perform a first scan of a first portion of the core sample;
after scanning the core sample, cut the core sample using a fluid jet; and
after cutting at least a portion of the core sample, perform a second scan of a second portion of the core sample.
17. The method of claim 16 , wherein the second portion of the core sample includes an interior portion of the core sample.
18. The method of claim 16 , further comprising causing the contiguous system to package the cut core sample.
19. The method of claim 16 , further comprising causing the contiguous system to extract the core sample from a core tube, wherein the extraction moves the core sample along a path of the fluid jet.
20. The method of claim 16 , further comprising causing the contiguous system to place one or more marking indicia on the core sample.
