Abstract

Video of an above ground effect of a subterranean event is received. The subterranean event is identified using Eulerian video magnification of the received video.

Claims

1. A method, comprising:

receiving video of an above-ground effect of a subterranean event; and

identifying the subterranean event using Eulerian video magnification of the received video.

2. The method of claim 1, where receiving video comprises receiving video of a terranean surface about a well site.

3. The method of claim 2, where receiving video of the terranean surface comprises receiving video of a plurality of upstanding markers supported to move with the terranean surface.

4. The method of claim 2, where identifying the subterranean event comprises identifying one or more of a subterranean fracture or a seismic signal induced by a seismic source device.

5. The method of claim 4, where identifying the subterranean event comprises identifying a characteristic of a subterranean fracture or a seismic signal.

6. The method of claim 1, where receiving video comprises receiving video of equipment at a well site.

7. The method of claim 6, where identifying the subterranean event comprises identifying operation of a tool in a well.

8. The method of claim 7, where identifying the subterranean event comprises identifying a characteristic of the operation of the tool.

9. The method of claim 1, where receiving video comprises receiving video while drilling a well.

10. The method of claim 9, where receiving video comprises receiving video of an effect on the event on drilling equipment;

and

where identifying the event comprises identifying bit whirl, bit wear, or sticking of a drill bit.

11. The method of claim 1, where receiving video comprises receiving video while producing from or injecting into a well.

12. The method of claim 1, where identifying the subterranean event comprises identifying the subterranean event concurrently with occurrence of the subterranean event.

13. The method of claim 1, comprising storing the received video;

and

where identifying the subterranean event comprises identifying the subterranean event after the occurrence of the subterranean event.

14. A system, comprising:

a camera aimed to take video of an above-ground effect of a subterranean event;

a computing device in communication with the camera to receive the video and apply Eulerian video magnification to the received video to produce enhanced video; and

a display to output the enhanced video.

15. The system of claim 14, where the camera is aimed to take video of a terranean surface.

16. The system of claim 14, where the ground comprises a well site.

17. The system of claim 14, where the camera is aimed to take video of a piece of equipment at a well site.

18. The system of claim 17, where the equipment comprises a coating that changes color in response to strain or temperature.

19. The system of claim 14, where the camera comprises a thermal camera.

20. The system of claim 14, comprising a housing at least partially in the ground and containing a target supported on a movement sensitive base, the target being in the view of the camera.

21. A method, comprising:

receiving video of a site;

applying Eulerian video magnification to the received video to produce an enhanced video; and

identifying a subterranean event from the enhanced video.

22. The method of claim 21, where applying Eulerian video magnification comprises applying Eulerian video magnification to magnify movement or color of a terranean surface or equipment associated with a well.

23. The method of claim 21, where receiving video of a site comprises receiving video of an effect produced by the subterranean event at a well site.
