Abstract
Embodiments of the present invention provide methods and apparatus for cables having one or more fibers that may function as a sensing device within a wellbore, wherein the fibers do not adhere to each other or to an inner wall of the cable during a high temperature operation, such as in a thermal recovery operation that may last over 30 days.
Claims19
A method comprising:
- providing a tube plus one or more fibers;
- applying a high temperature rated substance to the one or more fibers;
- and
- deploying the one or more fibers into the tube to provide a cable, wherein the substance prevents the one or more fibers from adhering to each other or to an inner wall of the cable during a high temperature operation.
1 more element
A method comprising:
- providing a cable with one or more fibers;
- and
- filling the cable with a high temperature rated substance, wherein the substance prevents the one or more fibers from adhering to each other or to an inner wall of the cable during a high temperature operation.
A method comprising:
- providing a cable with one or more fibers;
- and
- injecting a high temperature rated filler material into the cable, wherein the filler material fills void spaces within the cable surrounding the one or more fibers and prevents the one or more fibers from adhering to each other or to an inner wall of the cable during a high temperature operation.
A cable suitable for a high temperature operation, comprising:
- a tube;
- one or more fibers disposed in the tube;
- and
- a high temperature rated substance disposed over the one or more fibers, wherein the one or more fibers do not adhere to each other or to an inner wall of the cable during the operation.
1 more element
A method comprising:
- producing one or more fibers with a high temperature rated coating;
- and
- deploying the one or more fibers into a tube to provide a cable, wherein the coating prevents the one or more fibers from adhering to each other or to an inner wall of the cable during a high temperature operation.
