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.

Composite tubing

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).

Fiber reinforced spoolable pipe

Methods and apparatus for spalling a material, for example to thermally drill a wellhole, are provided. Such methods may include directing a fluid having a temperature greater than about 500&#xb0; C. above the ambient temperature of the material and less than about the temperature of the brittle-ductile transition temperature of the material to a target location on the surface of the material, wherein the fluid produces a heat flux of about 0.1 to about 50 MW/mat an interface between the fluid and the target location, and thereby creating spalls of the material.

Methods and apparatus for thermal drilling

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 that includes a solid hydrocarbon matrix. 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).

Reinforcing matrix for spoolable pipe

A composite article is provided that includes a polyolefin layer, a tie-layer, and a non-polyolefin. The tie-layer may comprise a silicon modified polyolefin. Methods are also provided for adhering a polyolefin to a non-polyolefin. Such articles may used, for example, in composite tubing.

Tie-layer materials, articles and methods for making and using same

A buoyancy control system for controlling the buoyancy of a tube may includes generally tubular length of buoyancy control material having a selected buoyancy characteristic. The length of buoyancy control material may be attached to a section of the length of the tube to adjust the buoyancy of the section of the tube. The length of buoyancy control material may be an integral, coaxial layer of the tube or, alternatively, the length of buoyancy control material may be externally attached to tube. In embodiments in which the length of the buoyancy control material is externally attached, the buoyancy control material may have a longitudinal axis that is spaced-apart from a longitudinal axis of the tube.

Buoyancy control systems for tubes

Buoyancy control methods for tubes are described. In one embodiment, a buoyancy control method can include a composite tube and a buoyancy control material for controlling the buoyancy of the composite tube. The composite tube can include an internal liner an external coaxial composite layer of fibers embedded in a matrix. One or more portions of the buoyancy control material can be attached to one or more portions of the composite tube to adjust the buoyancy of the one or more portions of the tube.

A treatment system for waste gas containing VOCs is composed of a zeolite revolver ( ), an incinerator ( ) and a network of pipes, valves and filters. The zeolite revolver ( ) consists of an adsorption zone ( ), a purge zone ( ), and a desorption zone ( ) to remove VOCs from untreated waste gas in the adsorption zone ( ) and then separate the VOCs from the saturated zeolite in the desorption zone ( ). The zeolite is cooled down in the purge zone ( ) so it can be used again. The separated VOCs are piped into the incinerator ( ) to be used as fuel. Whereby, the treatment system for waste gas containing VOCs operates efficiently and economically.
