Publication number: 20160215578Abstract: A technique facilitates deployment of a communication line in a borehole, e.g. a wellbore, to enable monitoring of parameters along the borehole. A communication line is coupled with an anchor and conveyed into the borehole from a surface location. The anchor is then released at a desired location along the borehole with the communication line. The communication line is deployed from the anchor so as to extend along the borehole until reaching a desired uphole location, e.g. a location proximate the surface.Type: ApplicationFiled: January 27, 2015Publication date: July 28, 2016Inventors: Sarmad Adnan, John R.
