Purging of Fiber Optic Conduits in Subterranean Wells
First Claim
1. A downhole optical sensing system, comprising:
- at least one optical line;
at least first and second tubular conduits, the first conduit being positioned within the second conduit, and the optical line being positioned within at least one of the first and second conduits; and
a purging medium flowed in a first direction through the first conduit, and flowed in a second direction opposite to the first direction between the first and second conduits.

Abstract
Purging of fiber optic conduits in subterranean wells. A downhole optical sensing system includes an optical line, at least two tubular conduits, one conduit being positioned within the other conduit, and the optical line being positioned within at least one of the conduits, and a purging medium flowed in one direction through one conduit, and flowed in an opposite direction between the conduits. A method of purging a downhole optical sensing system includes the steps of: installing at least two conduits and an optical line in a well as part of the sensing system, one conduit being positioned within the other conduit, and the optical line being positioned within at least one of the conduits; and flowing a purging medium through the conduits in the well, so that the purging medium flows in one direction through one conduit and in an opposite direction between the conduits.
