    Abstract: An expanding screen has an associated spirally wrapped exterior control line. The control line rests in a spiral trough made up in an exterior perforated jacket. The trough can be made by a pair of ridges disposed substantially parallel to each other or by an ordered spacing of raised dimples in the outer perforated jacket to create spiral troughs. At the screen connections centralizers having a spiral path or paths within can serve a dual function of locating the screen prior to expansion and protecting the control line in the joint area. A fiber optic cable can be placed in the control line.

    Abstract: A flow conduit may have at least one orifice is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier. The flow pathway between the orifice and the source is temporarily blocked with a degradable material or barrier. The material disintegrates (e.g. under the influence of time or temperature) to optionally produce a product that removes the temporary coating in the area adjacent the barrier. The method is useful in one non-limiting context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the temporary coating is a filter cake.

    Abstract: An expanding screen (10) with an associated sprirally wrapped exterior control line (22) is disclosed. The control line rests in a spiral trough (24) made up in an exterior perforated jacket. The trough can be made by a pair of ridges (26) disposed substantially parallel to each other or by an ordered spacing of raised dimples in the outer perforated jacket to create spiral troughs. At the screen connections centalizers (18) having a spiral path or paths within can serve a dual function of locating the screen prior to a expansion and protecting the control line in the joint area. A fiber optic cable can be placed in the control line.

    Abstract: Drilling a well to total depth without tripping the bit out of the hole despite encountering a troublesome zone is made possible by using a memory based composite material delivered with the drill pipe or advanced over it, as needed. The material can be activated as a troublesome zone is encountered and assumes as former configuration that places it in sealing relation to the troublesome zone in the bore hole while spacing it from the drill pipe so as to allow resumption of drilling with the troublesome zone isolated.
