20090090499 | WELL SYSTEM AND METHOD FOR CONTROLLING THE PRODUCTION OF FLUIDS - Embodiments of the present invention allow the placement of a stand alone device (valve) along a flow path, without a physical connection to the surface or reliance on the borehole for signaling, to provide a means to control the flow between reservoirs. This is achieved using a valve located in the flow path that can be actuated without sending signals down the borehole or well path and thereby eliminating the need for complicated signal lines and or fluid columns to actuate the valve. | 04-09-2009 |
20090188661 | GRAVITY DRAINAGE APPARATUS - A hydrocarbon production apparatus comprises an injection well, perforated casing, hydrocarbon viscosity reducing fluid injection tubing, a first wellbore restrictor, and a production well. The injection well is bored above the production well within a hydrocarbon reservoir below a ground surface. The injection well comprises a heel end and a toe end. The perforated casing is positioned along a length of the injection well. The hydrocarbon viscosity reducing fluid injection tubing is disposed within the injection well and has a hydrocarbon viscosity reducing fluid injection end. The first wellbore restrictor is transversely disposed within the perforated casing to control hydrocarbon viscosity reducing fluid flow along the injection well, the first wellbore restrictor being spaced closer to the toe end of the injection well than the hydrocarbon viscosity reducing fluid injection end of the hydrocarbon viscosity reducing fluid injection tubing is to the toe end. The first wellbore restrictor is movable through the injection well under control from the ground surface. This apparatus allows the propagation of, for example, the steam chamber in a steam assisted gravity drainage operation to be precisely controllable and adjustable, in order to more efficiently produce hydrocarbons from the hydrocarbon reservoir. | 07-30-2009 |
20100155048 | INTEGRATED CARBON MANAGEMENT SYSTEM FOR PETROLEUM REFINING - An environmentally and economically more efficient petroleum production/refining/utilization system for managing carbon emissions at all stages of the petroleum lifecycle is provided. The system of the current invention integrates the release of carbon from refined low value, high polluting petroleum products such that those sources of carbon may be utilized in a manner beneficial to the efficiency and environmental footprint of the overall petroleum processing lifecycle. | 06-24-2010 |
20100300672 | Time and efficiency manifold - A manifold for connecting one or more well service or completion apparatuses to a plurality of hydrocarbon wells comprises a block member which includes a flow bore having an inlet branch and a number of outlet branches, an inlet cross which is connected to the block member over the inlet branch, the inlet cross comprising an outlet bore which is in fluid communication with the inlet branch and a number of inlet bores which are in fluid communication with the outlet bore, a number of valves, each of which is connected to the bock member in fluid communication with a corresponding outlet branch, and a number of outlet crosses, each of which is connected to a corresponding valve. Each outlet cross comprises an inlet passage which is in fluid communication with the valve and plurality of outlet passages which are in fluid communication with the inlet passage. Accordingly, one or more fluids may be communicated simultaneously into the flow passage through the inlet bores in the inlet cross, and the fluids may be selectively communicated simultaneously through all of the outlet passages of a corresponding outlet cross by operation of its corresponding valve. | 12-02-2010 |

20140318760 | System and Method for the Access of Subterranean Deposits - According to one embodiment, a system for accessing a subterranean zone from the surface includes a well bore extending from the surface to the subterranean zone, and a well bore pattern connected to the junction and operable to drain fluid from a region of the subterranean zone to the junction. | 10-30-2014 |
20150122476 | DEVICE AND METHOD FOR SEQUESTERING A SUBSTANCE - There are provided a carbon dioxide storage apparatus and a carbon dioxide storage method which, through direct injection of carbon dioxide into an underground brine aquifer, can store carbon dioxide efficiently in the brine aquifer. A filter formed of, for example, grindstone is provided at a tip portion of an injection well. A pumping apparatus pumps carbon dioxide stored in a carbon dioxide tank. The pumping apparatus feeds carbon dioxide from the carbon dioxide tank into the injection well by means of a pump. In the pumping apparatus, carbon dioxide is held within a predetermined pressure range and a predetermined temperature range. Carbon dioxide is fed through the injection well, and is injected into a brine aquifer. Carbon dioxide injected into the brine aquifer assumes the form of microbubbles. | 05-07-2015 |
20150122477 | METHOD OF HYDROCARBON RESOURCE RECOVERY INCLUDING ACTUATOR OPERATED POSITIONING OF AN RF SENSOR AND RELATED APPARATUS - A method of hydrocarbon resource recovery from a subterranean formation may include forming a plurality of spaced apart injector/producer well pairs in the subterranean formation. Each injector/producer well pair may include a laterally extending producer well and a laterally extending injector well spaced thereabove. The method may include forming an intermediate well adjacent a given injector/producer well pair, and operating a positioning actuator to position a radio frequency (RF) sensor coupled to the positioning actuator to at least one predetermined location within the intermediate well. The method may further include operating the RF sensor at the at least one predetermined location within the intermediate well to selectively sense at least one corresponding portion of the subterranean formation adjacent the given injector/producer well pair. The method may also include recovering hydrocarbon resources from the plurality of injector/producer well pairs including the given injector/producer well pair. | 05-07-2015 |
