Abstract
Methods and tools for deploying cables, such as fiber optic cable, downhole in well using adhesive to adhere the cable to an inside surface of a casing.
Claims16
A method of installing a cable downhole in a well, comprising:
- a) deploying a spool of cable down a casing in a well so that said cable unwinds and lies against an interior wall of said casing;
- b) applying an epoxy resin and a hardener against said cable, wherein said epoxy resin is applied to said cable using an inline resin applicator at a surface during said deploying step a) and said hardener is applied after said cable is fully deployed;
- and
- c) hardening said epoxy resin so that said cable is affixed against said interior wall.

A method of installing a cable downhole in a well, comprising:
- a) deploying a spool of cable down a casing in a well so that said cable unwinds and lies against an interior wall of said casing;
- b) applying an epoxy resin and optionally a hardener against said cable;
- and
- c) hardening said epoxy resin so that said cable is affixed against said interior wall;
- wherein said deploying step uses a tool, said tool comprising:
- i) a housing having a front end and a back end;
- ii) said housing containing said spool that is configured to unwind said cable from said spool as said tool is deployed;
- iii) said housing having a cable port for egress of said cable at said back end;
- iv) two or more pressors attached to said housing and configured for outward bias of said pressors and said egressed cable against said interior wall;
- v) said housing containing an adhesive tank containing said epoxy resin;
- vi) said adhesive tank having an outlet fluidly connected to a first feed line;
- vii) said first feed line depositing said epoxy resin onto said egressed cable at or behind said pressors.
