    摘要: Methods and apparatuses for recovering heavy oil that, at least in one embodiment, include conditioning a reservoir of interest, then initially producing fluids and particulate solids such as sand to increase reservoir access. The initial production may generate high permeability channels or wormholes in the formation, which may be used for heavy oil production processes such as cold flow (CHOPS) or enhanced production processes such as SAGD, or VAPEX.

    摘要: Methods for recovering heavy oil are provided. In at least one embodiment, the process includes conditioning a reservoir of interest, then initially producing fluids and particulate solids such as sand to increase reservoir access (“slurry production”). The initial production may generate high permeability channels or wormholes in the formation, which may be used for heavy oil production processes (“hydrocarbon production”) such as cold flow (CHOPS) or enhanced production processes such as SAGD, or VAPEX.

    摘要: Well logging method and logging tool for measuring cement density and thickness at different azimuth angles for a cemented, cased well. The method uses a gamma source, a short-spaced detector, a long-spaced detector, and preferably a backscatter detector, where the detector-to-source spacings are designed for calculating (93) thickness and density of the cement annulus (94) from the detector count rates (91).

    摘要: Systems and methods for enhancing production of viscous hydrocarbons from a subterranean formation. The methods may include heating a hydrocarbon solvent mixture to generate a vapor stream, injecting the vapor stream into the subterranean formation to generate reduced-viscosity hydrocarbons, and producing the reduced-viscosity hydrocarbons from the subterranean formation. The methods also may include selecting a composition of the hydrocarbon solvent mixture by determining a threshold maximum pressure of the subterranean formation, determining a stream temperature at which the vapor stream is to be injected into the subterranean formation, and selecting the composition of the hydrocarbon solvent mixture based upon the stream temperature and the threshold maximum pressure. The systems may include a hydrocarbon production system that may be configured to perform the methods and/or that may include an injection well, an injectant supply assembly, and a production well.

    摘要: A system for and methods of producing hydrocarbons from a formation. A method may include drilling a wellbore in a formation, forming a first fracture in the formation that emanates from the wellbore, forming a second fracture in the formation that emanates from the wellbore and is approximately parallel to the first fracture, and simultaneously (a) injecting a fluid from an injection tubing string in communication with the second fracture and (b) producing hydrocarbons that travel from the first fracture into a production tubing string that is substantially parallel to the injection tubing string. The wellbore may be substantially horizontal. The fluid may increase pressure in an area of the formation adjacent to the first fracture.

    摘要: Described is a well completion for evenly distributing a viscosity reducing injectant (e.g. steam and/or solvent, e.g. in SAGD or CSS) into a hydrocarbon reservoir (e.g. of bitumen), for evenly distributing produced fluids (most specifically vapor influx) and for limiting entry of particulate matter into the well upon production. On injection, the injectant passes through a limited number of slots in a base pipe, is deflected into an annulus between the base pipe and a screen or the like, and passes through the screen into the reservoir. On production, hydrocarbons pass from the reservoir through the screen into a compartmentalized annulus. The screen limits entry of particulate matter (e.g. sand). The hydrocarbons then pass through the slots in the base pipe and into the well. Where a screen is damaged, the compartmentalization and the slots in the base pipe limit particulate matter entry into the well.

    摘要: Systems and methods for improving reservoir fluid recovery from fractured subterranean formations. The methods may include injecting a pressurizing fluid into an injection fracture that extends within a subterranean formation and producing a produced fluid from a production fracture that extends within the subterranean formation. The production fracture is spaced apart from the injection fracture and is in indirect fluid communication with the injection fracture via a portion of the subterranean formation that extends therebetween and the pressurizing fluid injection provides a motive force for the production of the produced fluid. The methods further include injecting a foaming agent into the production fracture to limit production of the pressurizing fluid from the production fracture. The systems may include hydrocarbon production systems that may be utilized to perform the methods and/or that may be created while performing the methods.
