Patent number: 8313152Abstract: In one embodiment, a method of hydraulically mining of oil sands from a well pair drilled into an oil sands deposit is disclosed. The wells are preferably installed from a protected underground workspace in or near the producing zone. The method of hydraulic mining disclosed herein includes: means of drilling production and tailings injection wells; means of augmenting hydraulic excavation for example by inducing block caving and/or wormholing; means of isolating the underground personnel areas from formation gases and fluids; and means of backfilling the excavated volumes with tailings. In one configuration, production wells are formed and lined with a frangible material, for example, a weak concrete or an inflatable epoxy-impregnated felt tube. Hydraulic mining of the full deposit thickness using a directional water jet bit begins at the far end of the drill hole and continues back in stages toward the well-head.Type: GrantFiled: November 21, 2007Date of Patent: November 20, 2012Assignee: Osum Oil Sands Corp.Inventors: Dana Brock, Andrew Squires, John David Watson

Patent number: 8244419Abstract: A marine power system comprises a motor for providing propulsion. It also comprises an energy storage unit (ESU) for storing and supplying energy to the motor. A prime power system is connected to the ESU and motor for selectively providing energy to these subsystems through a bus. The motor selectively receives energy from the prime power system and the ESU and can supply regenerative braking energy to the bus. The system can also accommodate multiple generator sets providing system power. The ESU can also provide starting power for the prime power system. Alternately, the prime power system drives a mechanical power system output shaft connected to the motor, and the marine system comprises an alternator driven by the prime power system output shaft. The ESU can transmit energy to the alternator. The prime power system can be located on a tugboat displacing a barge carrying the energy storage unit.Type: GrantFiled: October 24, 2007Date of Patent: August 14, 2012Assignee: Mi-Jack Canada, Inc.Inventors: Frank Wegner-Donnelly, John David Watson

Publication number: 20120132424Abstract: The present invention discloses a selection process for installing underground workspace in or near a hydrocarbon deposit that is an appropriate workspace from which to drill, operate and service wells applicable to any of a number of methods of recovering hydrocarbons. The present invention includes a number of innovative methods for developing workspace for drilling from a shaft installed above, into or below a hydrocarbon deposit, particularly when the hydrocarbon reservoir is at significant formation pressure or has fluids (water oil or gases) that can enter the workspace. These methods can also be used for developing workspace for drilling from a tunnel installed above, into or below a hydrocarbon deposit. The present invention also discloses a procedure for evaluating the geology in and around the reservoir and using this information to select the most appropriate method of developing workspace for drilling from a shaft and/or tunnel.Type: ApplicationFiled: February 2, 2012Publication date: May 31, 2012Applicant: OSUM OIL SANDS CORP.Inventors: John David Watson, Michael Helmut Kobler, Dana Brock
