  • Patent number: 9567509
    Abstract: Polymeric naphthenate inhibitors are delivered into production fluids to contact mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. These polymeric naphthenate inhibitors exhibit surface-active properties causing the inhibitors to self-associate at oil-water interfaces and inhibit interactions between organic acids in the oil and cations or cation complexes in water. The large surface area makes these polymers persistent and effective at low concentrations. These compounds also inhibit aggregation of organic acid carboxylate salts that form when pH and pressure conditions are amenable to organic acid ionization. Preferred inhibitors do not form emulsions due to the formation of unstable mixed interface structures that result in coalescence of dispersed droplets.

  • Patent number: 9556722
    Abstract: The invention relates to a method of extracting oil from a reservoir. The method comprises the following steps: drilling of a first well; mounting and cementing of well pipes in the first well; mounting of a Blow Out Preventer or Lubricator in the top of the well. At a distance from this well, a second well is drilled against a section of the first well such that the second well gets into operational contact with the first well. Hereafter well pipes are mounted and cemented in the second well; a Blow Out Preventer or Lubricator is mounted in the top of the second well; where after the drilling from the first or the second well is continued down into the reservoir.

  • Patent number: 9303500
    Abstract: A method for initiating steam assisted gravity drainage (SAGD) mobilization and recovery of hydrocarbons in a hydrocarbon-bearing formation includes initially forming a circulation path by connecting SAGD injection well and a circulation well. The circulation well can be a SAGD production well or a separate well completed adjacent a toe of the injection well. Initially, a thermal carrier such as steam or flue gases, is circulated, forming a thermal chamber about the injection well. One initial start-up is complete, the circulation path is decoupled for further propagating the thermal chamber and establishing steady-state SAGD operations.

  • Patent number: 9278315
    Abstract: A photovoltaic-thermal (PV-T) system and a method of cooling photovoltaic (PV) cells in the system is described herein. Energy from an excitation source such as the sun hits the PV cells in the PV-T system causing heating that reduces PV efficiency. The PV cells are cooled by fluid in an intact heat-transfer system making a heated water byproduct while the PV cells release a form of energy. In addition, the PV-T system can be implemented in a desalination plant to harvest energy and heat for desalination processes. The present invention also includes methods for transferring heat from PV cells to the earth to improve PV performance and reduce thermal shock to the PV cells.

  • Patent number: 9187992
    Abstract: A fracture extending away from a first subterranean well and toward a second subterranean well may be initiated by pumping fluid into the first subterranean well. The fracture may be propagated further towards the second subterranean well by continuing to pump fluid into the first subterranean well, while monitoring a pressure in the second subterranean well. Proppant may be pumped into the second subterranean well via the first subterranean well and the fracture upon detection of a change in the monitored pressure in the second subterranean well. The change in monitored pressure in the second subterranean well may be sufficient to indicate that the first and second wells are in fluid communication and interacting via the fracture.

  • Patent number: 9163490
    Abstract: An in-situ oil shale production system used for economically mobilizing and extracting hydrocarbons in an underground oil shale deposit. The production system includes a plurality of injection wells, a plurality of production wells and a thermal energy carrier, called herein “TECF”. The TECF is injected through the injection wells into a naturally occurring, highly-permeable zone. The highly-permeable zone is used to create a porous heating element. The porous heating element, at high temperatures in the range of 900 to 1300 degrees F., mobilizes and retorts the hydrocarbons in the porous heating elements. The hydrocarbons with the TECF then flow from the porous heating element through the production wells to the ground surface for refining. The surface area of the large porous heating element provides a means for economic, in-situ retorting of hydrocarbons from a carbon-rich, oil shale geologic formation.
