摘要： Isolation plugs may be installed in a wellbore flow control device to temporarily close a flow path therethrough. The isolation plugs may be installed in threaded openings often provided to for access to nozzles or other flow restrictors in the flow control devices. The isolation plugs may initially be locked in a closed configuration while being ran in hole and may be unlocked in response to the application of a predetermined activation pressure. Once unlocked, the isolation plug may not immediately move to an open configuration but may continue holding pressure to permit circulation and washdown operations to be conducted. The activation pressure may be reduced to a second predetermined threshold to lock the isolation plug in the open configuration wherein flow is permitted through the flow control device.

摘要： An apparatus for isolating a first zone from a second zone in a subterranean wellbore. The apparatus includes an outer tubular and an inner tubular disposed within the outer tubular forming an annular flow path therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path that is in fluid communication with the second zone. A sleeve having at least one seal is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path.

摘要： An apparatus and method for gravel packing an interval of a wellbore is disclosed. The apparatus comprises an outer tubular (110) forming a first annulus with the wellbore and an inner tubular (114) disposed within the outer tubular (110) forming a second annulus therebetween. The second annulus includes an axially extending slurry passageway (194) and an axially extending production pathway (190). The portion of the outer tubular (110) adjacent the slurry passageway (194) has an outlet (128). The portion of both the outer and inner tubulars (110, 114) adjacent the production pathway (190) has a plurality of openings (122, 146). The slurry passageway (194) is in fluid isolation from the production pathway (190) such that when a fluid slurry containing gravel is injected through the slurry passageway (194), the fluid slurry exits through the outlet (128) leaving gravel in the first annulus, thereby gravel packing the interval.
