ABSTRACT:
A technique usable with a well includes disposing a retractable line in a conduit having an open end located above a region of interest in the well. The retractable line comprises a sensing portion that, when the line is deployed, extends from the open end of the conduit and into the region of interest. Information observed by the sensing portion in the region of interest is communicated to the surface. When further well operations are to be performed in the region of interest, the retractable line is retracted until the sensing portion is located above the region of interest and below the surface. After the well operation is completed, the retractable line may be re-deployed such that the sensing portion again extends through the open end of the conduit and into the region of interest to continue observing characteristics associated with the well.
