Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: producing one or more fibers with a coating rated for a high temperature operation having a temperature above 300 degrees Celsius, wherein the coating is a highly-cured polyimide 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 the high temperature operation. 2.…
