Method of deployment for real time casing imaging
First Claim
1. A method for imaging a structure disposed in a borehole penetrating the earth, the method comprising:
- selecting a splice housing configured to be disposed in the borehole and comprising 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 comprises 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.

13. An apparatus for imaging a structure disposed in a borehole penetrating the earth, the apparatus comprising:
-
a fiber optic sensor configured to image the structure; a first fiber optic cable comprising an optical fiber configured to be spliced to the fiber optic sensor; and a splice housing configured to be disposed in the borehole and comprising a first port configured to seal the housing to the first fiber optic cable and a second port configured to seal the housing to the fiber optic sensor, wherein the housing comprises a sealed interior volume sufficient to contain a splice of optical fibers from the fiber optic sensor and the first fiber optic cable for protection and to enable a functional bend of at least ninety degrees for at least one spliced optical fiber. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
