Abstract:
The present disclosure is directed to embodiments of composite tubing having properties tailored to meet a wide variety of environmental and working conditions. Composite tubes disclosed herein may include one or more of the following layers: a internal liner, a composite layer, a thermal insulation layer, a crush resistant layer, a permeation barrier, buoyancy control layer, a pressure barrier layer, and a wear resistant layer. Grooves may be provided in one or more layers of the composite tube to provide increased axial permeability to the composite tube. A venting system, including vent paths, may be provided in the composite tube to vent fluid that may become trapped within the wall of the composite tube.
Abstract:
A spoolable pipe is disclosed, the spoolable pipe having an internal pressure barrier formed about a longitudinal axis, and a reinforcing layer(s) enclosing the internal pressure barrier. In one embodiment, the reinforcing layer(s) can include fibers having at least a partial helical orientation about approximately thirty and about approximately seventy degrees relative to the longitudinal axis, and, the wall can include at least one external layer enclosing the reinforcing layer(s) and having a permeability at least ten times greater than the permeability of the internal pressure barrier. The reinforcing layer(s) can further include a coating. The pipe can also include an energy conductor(s) integrated with and/or located between the internal pressure barrier and/or the reinforcing layer(s).
Abstract:
The invention includes systems and methods for operating, monitoring and controlling downhole fluid control system at a below ground location in a wellhole. The system may include a downhole fluid control system comprising at least one pump, a spoolable composite pipe comprising a fluid channel and at least one energy conductor, and a distal connection device adapted to couple a distal end of the fluid channel to the at least one pump and couple a distal end of the at least one energy conductor to the downhole fluid control system.
Abstract:
A system for conveying a fluid is disclosed. Such system comprises a spoolable tube comprising an inner layer comprising a first layer and a reinforcing layer comprising fiber, which defines a first passage for conveying a first fluid; an outer layer; and one or more fittings adapted to engage an axial end of said inner layer and an axial end of said outer layer.
Abstract:
A system and method for managing a new well or an existing well. The system includes a sensor and a control disposed within a well, a surface control system at the surface, a continuous tubing string extending into the well, and a conductor disposed on the continuous tubing string. The conductor connects the sensor and control to the surface control system to allow the surface control system to monitor downhole conditions and to operate the control in response to the downhole conditions. Another conductor may also be provided along the continuous tubing string to conduct power from a surface power supply to the control. The conductors are preferably housed in the wall of the continuous tubing string and may be electrical conductors, optical fibers, and/or hydraulic conduits. The control is preferably equipped with a sensor that verifies operation and status of the device and provides the verification to the surface processor via the conductor. Contemplated controls include valves, sliding sleeves, chokes, filters, packers, plugs, and pumps. The system can be installed through the production tubing of an existing well.
Abstract:
The invention includes systems and methods for removing fluids from a subterranean well. An example embodiment includes a system having a well casing surrounding at least one inner tubing string, where the inner tubing string has a distal section and a proximal section, a first fluid removal means within the distal section of the inner tubing string, and a second fluid removal means within the proximal section of the inner tubing string.

Abstract:
The present disclosure is directed to methods and systems for pipeline rehabilitation. The methods and systems disclosed herein permit the rehabilitation of long lengths of previously installed pipe and minimize the need for creating multiple access points to the pipeline. The disclosed systems and methods are particularly suited for rehabilitating buried and undersea pipelines or pipelines installed in areas of restricted access.
