Abstract

Video of an effect on equipment of an event is received. The event is identified using Eulerian video magnification of the received video.

Claims

1. A method, comprising:

receiving video of an effect of an event on well site equipment; and

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

2. The method of claim 1, where the event is obscured from view of the video.

3. The method of claim 1, where the equipment is subterranean.

4. The method of claim 1, where identifying the event comprises identifying and decoding communications

5. The method of claim 4, where the communications comprise fluid pulse telemetry signals from fluid from a well or acoustic telemetry signals carried as vibrations of the well site equipment.

6. The method of claim 1, where identifying the event comprises identifying a fluid property of a fluid in surface equipment, the fluid obscured from view of the video.

7. The method of claim 6, where the fluid property comprises flow rate.

8. The method of claim 1, where identifying the event comprises identifying damage obscured from view of the video or wear obscured from view of the video.

9. The method of claim 1, where identifying the event comprises identifying a blockage in a flow passage of the equipment, the blockage obscured from view of the video.

10. The method of claim 8, where the equipment comprises a subterranean well screen.

11. The method of claim 1, where identifying the event comprises identifying operation of a subterranean well tool.

12. The method of claim 1, where receiving video comprises receiving video of an effect of an event on a surface pump at the well site;

and

where identifying the event comprises identifying operating speed, cavitation, vapor lock, wear or damage.

13. The method of claim 12, where the pump is a frac pump or a gas injection pump.

14. The method of claim 1, where receiving video comprises receiving video of one of a surface marker on a surface of the equipment or an upstanding marker supported to move with the equipment.

15. A system, comprising:

a camera aimed to take video of an event on equipment at a well site; and

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.

16. The system of claim 15, where the equipment comprises, in view of the camera, one or more of a flag, a marker or a color change coating that changes color in response to strain or temperature.

17. The system of claim 15, where the camera is aimed to take video of drilling equipment or pumps at the well site.

18. The system of claim 15, where the equipment comprises a housing at least partially underground and containing the camera and a target supported on a movement sensitive base, the target being in the view of the camera.

19. The system of claim 15, where the camera comprises a thermal camera.

20. A method, comprising:

receiving video of equipment at a well site;

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

identifying an event that is obscured from view of the video using the enhanced video.

21. The method of claim 20, 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.

22. The method of claim 20, where receiving video of equipment at a well site comprises receiving video of an effect produced by the event.
