  • Patent number: 8875371
    Abstract: An articulating conduit linkage system for maintaining a fluid connection between a fluid source and displaceable conduit that has been buried in a subsiding permeable body. A fluid source can supply a working fluid through a source outlet. A displaceable conduit can receive the working fluid through a conduit inlet, and be buried at a depth within a subsiding permeable body that is contained within a permeability control infrastructure. A plurality of articulating conduit segments can include, an outer conduit segment coupled to the source outlet, an inner conduit segment coupled to the conduit inlet, and at least one middle conduit segment coupled to the outer and inner segments. In the event of a subsidence, the plurality of articulating conduit segments are configured so the outer and inner conduit segments extend the conduit linkage system while maintaining a working fluid connection between the source outlet and the conduit inlet.

  • Patent number: 8365478
    Abstract: A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A mined hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom. Hydrocarbon products can be collected from intermediate locations within the permeable body. Advantageously, an intermediate fluid collection system can be used to draw a hydrocarbon product from the permeable body at preselected locations. Such intermediate collection can provide hydrocarbon product fractions which can reduce or eliminate the need for full-scale distillation of a hydrocarbon product having a full range of products such as that typically found in crude oil.

  • Patent number: 8109047
    Abstract: A constructed permeability control infrastructure can include a permeability control impoundment defining a substantially encapsulated volume. A comminuted water-containing hydrocarbonaceous material can form a permeable body within the encapsulated volume. The impoundment includes a water vapor outlet for removing water vapor from the encapsulated volume. A heating device is also embedded within the permeable body to provide convective heating thereof. The permeable body can be heated sufficient to initially remove water therefrom as a water vapor. The water vapor can be removed from the infrastructure via the outlet which can be controlled or shut off when the permeable body is sufficiently dewatered. The dewatered permeable body can then be heated sufficient to remove hydrocarbons therefrom. During heating the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure.

  • Patent number: 6772840
    Abstract: A flow assurance system includes an inner pipe disposed within an outer pipe to assure flow through the outer pipe. During installation and relative axial movement with the outer pipe, the inner pipe is nearly neutrally buoyant or fully neutrally buoyant in the fluids of the outer pipe and may extend partially or completely through the outer pipe. The inner pipe may be anchored at one end within the outer pipe. The inner pipe is preferably composite coiled tubing that is installed using a propulsion system. The system may allow fluids to flow through the inner pipe and commingle with the fluids in the outer pipe or may flow fluids through the inner pipe to the exterior of the outer pipe. Hot fluids may pass through the inner pipe to maintain the temperature of the fluids flowing through the outer pipe and chemicals may flow through the inner pipe to condition the fluids in the outer pipe. Tools may be attached to the end of the inner pipe for conducting flow assurance operations within the outer pipe.
