Abstract: An improved method and system of deploying a pipeline for fiber optic sensing applications. A plurality of pipe sections (11) are provided each having an internal pipe (13) surrounded by material layer(s). Opposed ends (17A) of each pipe section have a portion of the surrounding layer(s) removed or omitted. A tubular member (19) extends lengthwise along each pipe section within the surrounding layer(s) and has free ends (19A) that extend from respective terminal walls (20A) of the surrounding layer(s). Adjacent pipe sections are joined together. The tubular members of adjacent pipe sections are joined together to form a conduit that extends along the pipeline. The conduit is adapted to carry one or more fiber optic waveguides therein. At least one second layer of material is applied to the area between the joined pipe sections. The surrounding layer and the at least one second layer provide for insulation and/or protection of the internal pipes of the pipeline.

Abstract: When drilling or completing an oil or gas well, it is often desirable to drill a borehole at an angle to the initial borehole. A process for deflecting a well tool towards the wall of a well bore comprises positioning within the well bore a radially expandable pipe designed to curve longitudinally when its diameter is expanded, expanding the diameter of the radially expandable pipe thereby causing the pipe to curve and passing the well tool through the curved pipe: The process is particularly suitable for through-tubing operations in which a lateral bore is initiated from a production well having within the well a smaller diameter production tubing (14) comprising (i) passing through the production tube (14) a radially expandable pipe (1) designed to curve longitudinally as its diameter is expanded, into a section of well bore (12) having a diameter greater than the diameter of the production tubing (14) (ii) expanding the diameter of the radially expandable pipe (1) thereby causing the pipe to curve, (iii) passing through the curved pipe a milling device or drill bit and (iv) milling the casing or drilling into the well bore wall.
