摘要： A downhole valve features a flow port that can be selectively obstructed by a pressure actuated sleeve that is movable in a pin and slot mechanism to rotate while being cycled up and down by application and removal of pressure in a cyclical manner. When the sleeve is cycled to the port closed position, a flapper mounted near its upper end can fall on a seat on the sleeve to allow pressure to be applied to the flapper and sleeve, causing the sleeve to move to a position that will prevent fluid loss from the tubular string into the formation. The Closed flapper allows pressure cycles of the sleeve. A double closure against fluid loss can be affected.

摘要： Multiple producing zones separated by a non-producing zone are gravel packed together. The non-producing zone has locations to take returns so as to get a consistent pack in the non-producing zone. The production string features external seals and/or an internal plug so that no matter which producing zone is aligned to produce, the screens in the non-producing zone are selectively isolated so that the producing zone that is not intended to be produced has only the path through the gravel pack to get to the actual zone being produced. Since the annulus can be long and full of gravel this path will make flow from the zone that is not of interest minimal into the flow from the zone of interest without using a packer between pairs of spaced apart producing zones.

摘要： A completion assembly facilitates gravel-packing and fracturestimulation of closely spaced zones. The assembly includes a pair of spaced screens with a production packer in between. The production packer has a short bypass flowpath therethrough to allow fluids carrying the gravel to pass the production packer so that the upper and lower zones can be gravel-packed simultaneously, as well as fracture-stimulated simultaneously. Thereafter, the presence of the gravel in the bypass tube in the packer between the zones provides some limited isolation based on the permeability of the gravel found in the bypass passage and the pressure drop across that passage. Production then can follow from the lower zone, the upper zone, or both zones depending on the completion configuration.

摘要： An intelligent well system can service three or more zones that have gravel packed screens. A modular system features a screen and a surface controlled production valve on an internal blank pipe that internally straddles the screen. A gravel exit valve is disposed above the blank pipe and the blank pipe can optionally have a fluid loss control valve. A gravel pack/fracturing assembly can engage each module and close the fluid loss valve and gravel outlet valve on the way out of a module. Optionally the fluid loss valve can be eliminated if the gravel packing and fracturing string has the ability to power the production valve. The modules can be connected by wet connects as can the production string to make the intelligent well system functional from the surface.

摘要： An improved adjustable track cover assembly is provided which facilitates adjustable positioning of a track cover over a work blank feed track and which maintains the position established. The track cover assembly includes a cover supporting bracket which is operatively supported by an adjusting screw in threaded engagement therewith. The adjusting screw is supported for selective adjusting rotation relative to the cover bracket. Snubbing means, including spring means and a member in threaded engagement with the adjusting screw, coact with the bracket to impede relative rotation between the bracket and adjusting screw and thereby maintain a fixed positioning of the track cover. Additional spring means, associated with the adjusting screw support, coact with the adjusting screw to maintain a fixed positioning of the adjusting screw.
