摘要： A valve assembly for integration within a wellbore string disposed within a hydrocarbon-containing reservoir is provided. The valve assembly includes a valve housing having a plurality of frac ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a bottom sleeve operatively mounted within the valve housing configured to selectively open the frac ports, and a top sleeve operatively mounted within the valve housing slidable between (i) a first position defining a first fluid pathway whereby fluid is flowable down into the central passage and into the reservoir via the frac ports, and (ii) a tracing position defining a second fluid pathway whereby fluid is flowable from the reservoir into an annulus defined between the top sleeve and the housing. The valve assembly also has a tracer compartment defined within the annulus forming part of the second fluid pathway and accommodating a tracer material.

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 apparatuses of a flow communication station a flow control apparatus having a flow control member, and a shifting tool that is configured for coupling to the flow control member. While the shifting tool is coupled to the flow control member, application of a pressure differential across the shifting tool urges movement of the flow control member for effecting opening of a port.

摘要： There is provided a flow control apparatus configured for integration within a wellbore string disposed within a wellbore extending into a subterranean formation and useable for effecting production of hydrocarbon material by providing flow communication for injection of treatment material for stimulating the reservoir and then receiving hydrocarbon material from the stimulated reservoir, and also for effecting production of hydrocarbon material by providing flow communication for injection of a displacement fluid for displacing hydrocarbon material to a second wellbore.

摘要： There is provided a flow control apparatus including a housing, a port, a flow control member, a sensor, and a trigger. The housing includes a housing passage. The port extends through the housing. The flow control member includes a fluid responsive surface, and is configured for displacement, relative to the port, such that fluid communication is effected between the port and the housing passage. The sensor is coupled to the housing for sensing an actuating signal. The trigger is configured for effecting fluid communication between the housing passage and the fluid responsive surface, in response to the sensing of an actuating signal by the sensor, for effecting displacement of the flow control member.

摘要： A fracturing valve comprising a tubular mandrel having a through bore continuous with a tubing string, and a frac window through the side of the tubular mandrel. An outer sleeve is radially disposed around the tubular mandrel. The outer sleeve includes a sleeve port in a sidewall. The tubular mandrel slides relative to the sleeve by application and release of set down weight on a coiled tubing string. When the valve is closed, there is no fluid communication from the tubing string out of the frac window. When the valve is open, fluid communication from the tubing string is enabled. The valve may be installed in a downhole tool having a perforation device. The tool string can be used with one sealing element as the tool is pulled up the hole isolating lower perforations, or with two sealing elements to allow pin-point treatments isolating perforations both up and downhole.
