Husky Energy Inc. is one of Canada’s largest integrated energy companies, headquartered in Calgary, Alberta. It is publicly traded on the Toronto Stock Exchange under the symbols HSE and HSE.PR.A. The Company operates in Western and Atlantic Canada, the United States and the Asia Pacific Region, with Upstream and Downstream business segments. Husky Energy is controlled by Hong Kong billionaire Li Ka-Shing who owns a majority share of approximately 70% according to Bloomberg and Financial Post data.Husky's foundation is in Heavy Oil and Western Canada, where it has extensive conventional oil and natural gas assets, significant heavy oil production and downstream operations, including refineries, upgrading facilities and pipelines. The Company is pursuing three growth pillars in the Asia Pacific Region, the Oil Sands and the Atlantic Region.In the Asia Pacific Region, Husky’s Liwan Gas Project in the South China Sea is progressing towards first gas. The company also holds exploration rights offshore Indonesia.Husky also has a portfolio of oil sands leases, encompassing some 2,500 square kilometres in the Fort McMurray region of northern Alberta. Its Sunrise Energy Project is on track for first oil in late 2014.In the Atlantic Region, off Canada's East Coast, the company holds interests in 20 exploration licenses and producing properties at Terra Nova and White Rose. In the United States, the company owns a refinery in Lima, Ohio and holds a 50 percent ownership interest with BP in a refinery at Toledo, Ohio. The company employs approximately 5,200 people , has approximately $36.9 billion in assets and produced an average of 312,000 barrels of oil equivalent per day in 2013, making it one of Canada's largest energy companies.

A method for stimulating heavy oil recovery from CHOPS wells at or nearing the end of productive life but not experiencing water-out, wherein produced water is heated to below boiling point and injected back downhole to reduce heavy oil viscosity in the near-wellbore region and surrounding the wormhole network, enabling existing reservoir pressure to drive the reduced-viscosity heavy oil toward the well for production to surface. The injection-soak-production cycle can be repeated as desired so long as adequate reservoir pressure exists.


A method and system for producing steam for use in heavy hydrocarbon recovery operations. Water, containing impurities, produced from the well is separated from hydrocarbons and other materials, and subsequently directly passed to a produced water boiler with online pigging. The boiler is indirectly heated by means of a hot flue gas, such as a gas turbine exhaust, which produces electricity (for powering a central processing facility, or alternatively a burner to heat the boiler) and exhaust heat for heating the boiler.


A method and system for producing steam for use in heavy hydrocarbon recovery operations. In an arrangement with or without a central processing facility and/or a plurality of well pads in communication with the central processing facility, each well pad is provided with equipment for separation of materials produced from its respective wells, and steam generation equipment for that well pad, thus allowing for simplified piping transport.


Improved SAGD methods for recovering heavy oil from underground formations. In a first aspect a method is provided for drilling, using multi-lateral drilling techniques, a series of horizontal collector wells from a vertical shaft of a production well, below and parallel to an injection well. In a further alternative to the typical SAGD configuration having injector and producer well drilled from the same end of a region under development, the production well is instead drilled at an end of a region of development opposite to an end of such region at which an injector well is drilled. Lastly, in yet another aspect, the invention comprises a method for rejuvenating an existing SAGD well pair, comprising drilling a further production well or wells at an opposite end of said formation at which an existing injector well was drilled, preferably using multi-lateral drilling techniques.


Methods and systems for enhanced thermal recovery of subsurface hydrocarbons comprising the use of multilateral branches, wherein the multilateral wells are completed in a manner to improve individual branch control.

A fuel dispensing nozzle 1, incorporating a poppet valve gasket 22 of truncated shape enhances the flow of fuel through the nozzle when actuated. A handle lever 5 for the nozzle, which is designed having an elongated and enlarged end, includes elongated slots 40 that are pivotally pinned through both the latch plate 19 and the handle link 28 in order to reduce the space between the interconnection between the front of the latch plate to the bottom of the automatic shutoff stem 17, such that by lessening the distance between these components, thereby reducing the fulcrum point for the calculation of the force necessary to open the nozzle by raising its handle lever, and reduces the force necessary to achieve nozzle opening and actuation, to less than 3,4 kPa pressure during usage and application.

A method for welding within a tubular member situated in a hydrocarbon wellbore. Downhole junctions for branch wellbores can be welded, casing windows for sidetrack drilling can be prepared, and casing repairs can be undertaken.


A method for reducing undesired water production from a hydrocarbon reservoir, wherein scale formation/deposition in a wellbore from localized water cut increases is used for zonal isolation. Slots or other aperture types are provided in a casing length such as a slotted liner, to encourage scale formation/deposition adjacent water-producing zones, thus isolating such zones and preferentially producing from hydrocarbon-producing zones.


A thermal hydrocarbon recovery method comprising cycling high pressure fluid injection for a period of time followed by low pressure fluid injection for a period of time, the high pressure injection primarily to dilate and enhance reservoir porosity/permeability and improve the subsequent low pressure fluid injectivity. The method is particularly useful for recovering heavy and extra heavy hydrocarbons from tight formations and/or low vertical permeability reservoirs under viscosity reduction and gravity drainage methods. This method is believed to be applicable for recovering heavy or extra heavy oil from reservoirs with geological risk associated with cap rock integrity.

Systems and methods for partially upgrading a produced heavy hydrocarbon resource at the production site (at the pad or a central processing facility) using indirect hydrogen addition, comprising a blender for blending the hydrocarbon with a hydrogen donator and a reactor for elevating the mixture to a temperature sufficient to hydrogenate the hydrocarbon to an API level required for pipeline specifications. The partially upgraded hydrocarbon can then be transported by pipeline to a refinery for further processing. The presence of catalysts and on-site hydrogen production equipment conventionally required for upgrading is eliminated. Further, the need for diluent which is conventionally used to enable pipeline ability of produced heavy hydrocarbon is reduced or eliminated, thus reducing the diluent freight cost and the required pipeline volume.
