  • Patent number: 8893793
    Abstract: Hydrocarbonaceous and additional products are recovered from nonrubilized oil shale and oil/tar sands. A hole is formed in a body of oil shale or oil sand. A heater is positioned into the hole generating a temperature sufficient to convert kerogen in oil shale or bitumen in oil sand to hydrocarbonaceous products, these products are extracted from the hole as effluent gas. One or more initial condensation steps are performed to recover crude-oil products from the effluent gas, followed by one or more subsequent condensation steps to recover additional, non-crude-oil products. The subsequent condensation steps may be carried out in at least one cooled chamber having a sequence of critical orifices maintained at a negative pressure. Carbon sequestration steps may be performed wherein recovered carbon dioxide is delivered down the hole following the recovery of the hydrocarbonaceous products.

  • Patent number: 8381814
    Abstract: To protect an underground aquifer from pollution due to the extraction of subsurface products from a recovery well or other subsurface mining operation, a plurality of barrier injection wells are formed around the recovery well/subsurface operation, each barrier injection well terminating in a groundwater layer to be protected. A polymer matrix material is then into the injection wells such that the material exiting each injection well expands and overlaps with material exiting from adjacent wells prior to solidification, thereby forming an isolation barrier within the groundwater layer. In the preferred embodiment, the polymer matrix material is a cellulose polymer hydrogel matrix material which is injected in gel form. Following recovery of the hydrocarbonaceous products from the recovery well(s), the injected polymer matrix material may be reheated and subsequently liquefied allowing full groundwater flow to occur.

  • Publication number: 20130000349
    Abstract: A system for recovering products from a gas stream comprises a cooled chamber having an inlet that feeds the gas stream to a plurality of sequential conduit loops within the chamber. A critical orifice follows each loop, and each loop includes an output port. Based upon the physical characteristics of each loop, the sizing of the critical orifice following the loop, and the temperature within the chamber, different products are condensed from the gas stream through the output ports. The system may be configured to condense hydrocarbonaceous products such as ethane, propane, butane or methane, as well as fundamental products such as carbon dioxide, nitrogen or hydrogen. Gaseous products may be stored in gas or liquid form or vented to atmosphere depending upon amount, purity, and so forth.

  • Patent number: 8312927
    Abstract: Apparatus and methods are described for recovering hydrocarbonaceous and additional products from nonrubilized oil shale and oil/tar sands. One or more initial condensation steps are performed to recover crude-oil products from the effluent gas, followed by one or more subsequent condensation steps to recover additional, non-crude-oil products. The effluent gas is maintained under a negative pressure from the hole and through the initial and subsequent condensation steps. This provides numerous advantages, including the adjustment of various physical parameters during the extraction process. Such adjustment allows the ratio of oils types to be varied, the ratio of hydrocarbonaceous products to non-crude products to be varied, contamination control, and other disclosed advantages.

  • Patent number: 8261831
    Abstract: Apparatus and methods recover hydrocarbonaceous and additional products from oil/tar sands. The method includes the steps of forming a hole in a body of oil or tar sand, positioning an apertured sleeve within the hole to minimize fill-in of the sand, positioning a gas inlet conduit into the apertured sleeve, and introducing a heated, pressurized processing gas into the sleeve through the gas inlet conduit, such that the heated, pressurized processing gas penetrates into the sand through the apertures, thereby converting bitumen within the sand into hydrocarbonaceous products. The processing gas and hydrocarbonaceous products are withdrawn as effluent gas through the hole under relative negative pressure. A mesh screen may be supported between the apertured sleeve and the body of oil or tar sand.
