Abstract: Apparatus having a fiber optic tether disposed in coiled tubing for communicating information between downhole tools and sensors and surface equipment and methods of operating such equipment. Wellbore operations performed using the fiber optic enabled coiled tubing apparatus includes transmitting control signals from the surface equipment to the downhole equipment over the fiber optic tether, transmitting information gathered from at least one downhole sensor to the surface equipment over the fiber optic tether, or collecting information by measuring an optical property observed on the fiber optic tether. The downhole tools or sensors connected to the fiber optic tether may either include devices that manipulate or respond to optical signal directly or tools or sensors that operate according to conventional principles.

Abstract: Methods for correcting temperatures measured in producing wells are provided. In one embodiment, a method includes receiving formation fluid within a completion string in a well, wherein the formation fluid passes from a formation and radially into the completion string through at least one opening in the completion string. The method also includes measuring temperatures outside the completion string at multiple depths in the well at which the formation fluid passes from the formation and radially into the completion string. The temperatures measured outside the completion string at the multiple depths in the well are converted into axial temperatures inside the completion string at the multiple depths. Additional systems, devices, and methods are also disclosed.

Abstract: A technique includes inducing a distributed temperature change along a portion of a wellbore and measuring a time varying temperature along the portion of the wellbore due to the induced change. The technique includes determining a distributed flow rate in the portion based at least in part on the measured time varying temperature before the temperature reaches equilibrium.

Abstract: 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.
Abstract translation: 一种技术有助于在钻孔中部署通信线路，例如。 井眼，以便能够监测沿钻孔的参数。 通信线路与锚固件联接并从表面位置传送到钻孔中。 然后锚通过通信线沿着钻孔在期望的位置释放。 通信线路从锚固部分展开，以便沿着钻孔延伸，直到达到所需的井上位置，例如， 靠近表面的位置。
