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.

First claim

We claim:

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.
