  • Patent number: 8025101
    Abstract: A cyclic steam soak (CSS) stimulation method for producing heated hydrocarbons from a viscous hydrocarbon-containing formation comprises the steps of: a) drilling a well (1) having a substantially horizontal or inclined lower section (3) into the viscous hydrocarbon-containing formation (4) substantially along the trajectory of the minimum compressive horizontal stress Sh; b) cutting at selected intervals along the length of the lower well section (3) substantially disk-shaped cavities (5A-5D) into the viscous hydrocarbon-containing formation (4) by a rotating hydraulic jet cutting device (6); c) completing the well (1); d) injecting steam into the well (1) and disk-shaped cavities (5A-5D) at such an elevated pressure that the hydraulic pressure in at least one disk-shaped cavity 5A is above the formation fracturing pressure, thereby fracturing the formation (4) and permitting the steam to invade the formation surrounding the fracture and to heat hydrocarbons in the steam invaded zone; e) interrupting steam i

  • Patent number: 7219734
    Abstract: A method for treating a hydrocarbon containing formation is described. The method may include providing heat from one or more heaters to at least a portion of the formation. At least one heater may be located in at least one wellbore in the formation. At least one wellbore may be sized, at least in part, based on a determination of formation expansion caused by heating of the formation so that formation expansion caused by heating of the formation is not sufficient to cause substantial deformation of one or more heaters in the sized wellbores. The ratio of the outside diameter of a heater to the inside diameter of a wellbore may be less than about 0.75. In certain embodiments, heat may transfer from the one or more heaters to a part of the formation. In some embodiments, a mixture may be produced from the formation.

  • Patent number: 7073578
    Abstract: A method for treating a hydrocarbon containing formation is described. The method for treating a hydrocarbon containing formation may include heating a first volume of the formation using a first set of heaters. A second volume of the formation may be heated using a second set of heaters. The first volume may be spaced apart from the second volume by a third volume of the formation. The first volume, second volume, and/or third volume may be sized, shaped, and/or located to inhibit deformation of subsurface equipment caused by geomechanical motion of the formation during heating.

  • Publication number: 20050125939
    Abstract: The invention relates to dirt separator module comprising a dirt-separation housing having an inlet and an outlet opening and defining a cyclonic airflow separator, and a suction source fluidly connected with the dirt-separation housing. A separator plate and a cylindrical wall of the dirt-separation housing form a toroidal cyclonic airflow chamber in the dirt-separator for aiding in the separation of dirt from a suction airstream developed by the suction source. The separator plate has an outer diameter smaller than the inner diameter of the cylindrical wall of the dirt-separation housing, creating a gap between the outer edge of the separator plate and the inner wall of the dirt tank. A further embodiment includes dual cyclonic separators fluidly connected through a filter assembly. A further embodiment includes a cyclonic separator in the form of a tangential helical ramp.

  • Publication number: 20050000053
    Abstract: A hand-held nozzle is attached to the end of a vacuum and fluid delivery hose of an upright deep cleaner. The nozzle includes a reservoir to contain a solution to be applied to a surface. When a solution delivery system of the deep cleaner is pressurized, water from the upright cleaner clean water tank is routed through the hose to the hand-held nozzle. The water is routed through a venturi valve connected to the reservoir, which draws the solution to the valve to mix with the water stream. The resultant mixture flows from the hand-held nozzle for application to a surface being treated. One embodiment of the solution reservoir includes a retainer cap bonded to the reservoir and utilizing a bayonet-type mounting arrangement for mounting the reservoir to a nozzle assembly.

  • Publication number: 20030201098
    Abstract: Systems and methods of using a computer system to simulate a process for in situ treatment of a hydrocarbon containing formation are provided. The in situ process may include providing heat from one or more heat sources to at least one portion of the formation. The in situ process may, in some embodiments, include allowing the heat to transfer from the one or more heat sources to a selected section of the formation. In some embodiments, the method may include operating the in situ process using one or more operating parameters. At least one operating parameter of the in situ process may be provided to the computer system. In certain embodiments, at least one parameter may be used with a simulation method and the computer system to provide assessed information about the in situ process.
