20090173406 | Fiber Reinforced Spoolable Pipe - 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). | 07-09-2009 |
20100089574 | Methods and Apparatus for Wellbore Enhancement - Methods for enhancing existing wells, such as increasing the diameter of an existing well by hydrothermal spallation are provided. Such methods may include providing a housing comprising a reaction chamber and a catalyst element held within the reaction chamber, providing at least one jet nozzle, contacting one or more unreacted fluids or solids with the catalyst element, wherein the unreacted fluid or solid is adapted to react with the catalyst element, thus generating a reacted fluid, and emitting the reacted fluid through the at least one nozzle, wherein the at least one nozzle may be directed to a production zone of an internal wall of the existing well. | 04-15-2010 |
20100089576 | Methods and Apparatus for Thermal Drilling - Methods and apparatus for spalling a geological formation, for example to thermally drill a wellhole, are provided. Such methods may include providing a housing comprising a reaction chamber and a catalyst element held within the reaction chamber, providing at least one jet nozzle, contacting one or more unreacted fluids or solids with the catalyst element, wherein the unreacted fluid or solid is adapted to react over the catalyst element, thus generating a reacted fluid, and emitting the reacted fluid through the at least one nozzle, wherein the at least one nozzle is directed to an excavation site within or on the geological rock formation, thereby creating spalls and/or a reacted rock region. | 04-15-2010 |
20100089577 | Methods and Apparatus for Thermal Drilling - 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° 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/m | 04-15-2010 |
20100101676 | Composite Tubing - 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. | 04-29-2010 |
20100218993 | Methods and Apparatus for Mechanical and Thermal Drilling - Methods and apparatus for excavation of a borehole in a geological formation are provided. Such methods may include providing a thermal system capable of providing substantially hot fluid, and comprising at least one jet nozzle, providing a mechanical drilling system comprising a drill bit, directing the substantially hot fluid through the jet nozzle towards the geological formation causing an altered portion of geological formation to form, and removing the altered portion using the drill bit, thereby creating cuttings and producing a borehole in the geological formation. | 09-02-2010 |
20120118423 | Fiber Reinforced Spoolable Pipe - 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). | 05-17-2012 |
20120266996 | Reinforcing Matrix for Spoolable Pipe - 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). | 10-25-2012 |
