Abstract
A method for imaging a structure disposed in a borehole penetrating the earth, the method including: selecting a splice housing having a first port configured to seal the housing to a first fiber optic cable and a second port configured to seal the housing to a fiber optic sensor configured to image the structure, wherein the housing includes a sealed interior volume sufficient to contain a splice of optical fibers for protection and to enable a functional bend of at least ninety degrees for at least one spliced optical fiber; disposing a splice between an optical fiber of the first fiber optic cable and an optical fiber of the fiber optic sensor in the splice housing; disposing the splice housing containing the splice in the borehole; attaching the fiber optic sensor to the structure; and disposing the structure in the borehole after the splice housing is disposed in the borehole.
