Method of borehole seismic surveying using an optical fiber |
| 摘要 |
A method of detecting seismic waves traveling through a subsurface formation includes lowering a cable into a borehole in the subsurface formation, the cable having at least one optical fiber associated therewith, and causing descent of a remote end of the cable to be arrested. The method further includes feeding a further length of the cable into the borehole such that the cable is slack and in contact with at least part of a wall of the borehole, and using an interrogator coupled to the at least one optical fiber to detect seismic waves traveling through the subsurface formation and into the cable. |

1. A method of detecting seismic waves traveling through a subsurface formation comprising:
lowering a cable into a borehole in the subsurface formation, the cable having at least one optical fiber associated therewith; causing descent of a remote end of the cable to be arrested; feeding a further length of the cable into the borehole such that the cable is slack and in contact with at least part of a wall of the borehole; and detecting seismic waves traveling through the subsurface formation and into the cable based at least in part on a response of the optic fiber to the seismic waves. |
