摘要： Disclosed is a rupture disc assembly for use in making a temporary seal in a vessel such as a casing string. The rupture disc assembly may include a rupture disc having a side surface that has a shallow angle taper inward towards a bottom surface of the rupture disc, and a mounting apparatus to support the rupture disc so that the rupture disc forms the temporary seal. When a disc working pressure is applied to a top surface of the rupture disc, engagement/force transmission between the rupture disc and the mounting apparatus produces enough radial compression in the rupture disc due to the shallow angle taper to significantly mitigate or cancel tensile stresses thereby avoiding the rupture disc from breaking. The rupture disc may be configured to break when the rupture disc is subjected to a disc working pressure that is greater than the disc rupture pressure, thereby removing the temporary seal. An axial abutment surface feature may be provided which is configured and operable to limit downward axial movement of the rupture disc relative to said disc support mechanism and thus be operable to restrict the amount of compression said tapered wall surface of said disc support mechanism can exert on said at least a portion of said rupture disc when the top surface of the rupture disc is subjected to said hydraulic pressure within the well.

摘要： There is provided a flow control apparatus configured for optimizing use of available space within the wellbore for conducting of fluids between the surface and the subterranean formation. The flow control apparatus is useable for conducting all forms of fluid, such as, for example, liquids, gases, or mixtures of liquids and gases. As well, the flow control apparatus is useable for effecting injection of fluid (e.g. a fluid for stimulating hydrocarbon production via a drive process, such as, for example, waterflooding, or via a cyclic process, such as “huff and puff”) into the subterranean formation, and for receiving production of fluid (e.g. hydrocarbon material) from the subterranean formation (including production that is stimulated by gas lift).

摘要： The present description relates to processes and systems for asynchronous frac-to-frac operations for recovering hydro-carbons. The processes can include the use of injection-only and production-only valves that include a housing and at least one sleeve as well as flow restriction components, check valves, or other features. The flow restriction component can be a tortuous path provided in the sleeve. The check valves can be integrated into the sleeve or into the housing of the valve. Various different types of valve assemblies can be used and integrated with flow restriction components and/or check valves.

摘要： Apparatuses, systems and methods for controlling production of hydrocarbon material disposed within a subterranean formation are provided. In one aspect, a method is provided for producing hydrocarbon material by displacement via flow communication station of a production well. Working states of the production well are analyzed by setting the flow communication stations in the working state, producing hydrocarbon material while in the working state, and sensing a characteristic of the produced material while in the working state. A working state that optimizes operating parameters of the of the production well is determined based on the sensed characteristic, and the production well is subsequently operated in that working state.

摘要： A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.

摘要： There is provided a downhole tool comprising a locator. The locator includes a wellbore coupler for becoming releasably retained relative to a locate profile; and a wellbore coupler release opposer configured for opposing release of the wellbore coupler from the retention relative to the locate profile. While the opposing of the release of the wellbore coupler from the retention relative to the locate profile is being effected by the wellbore coupler release opposer, relative displacement between the wellbore coupler release opposer and the wellbore coupler is effectible, with effect that the opposing is defeated. The locator also includes a displacement impeder for impeding the relative displacement between the wellbore coupler release opposer and the wellbore coupler.

摘要： There is provided a hydrocarbon production process including stimulating a hydrocarbon material-containing reservoir by hydraulic fracturing of the hydrocarbon material-containing reservoir with a treatment material including proppant. The treatment material is injected such that a frac pack is obtained. During production, hydrocarbon material is conducted from the reservoir to the surface via the frac pack. Flow control members are manipulated to enable injection of the treatment material and, subsequently, production of the hydrocarbon material from the reservoir.
