摘要： A well control valve assembly prevents flow from or to completion segments further downhole from the well control valve assembly once the stimulation stimulation/shifter string has been removed from the production tubing string. The well control valve assembly features a shaped flapper plate which, when opened, conforms closely to the shape and size of the production tubing string's interior diameter. The flapper plate is biased toward a closed position by a compression spring arrangement that includes an arm which levers the plate upward toward a seating surface. The valve assembly's closure is mechanically induced and is not responsive to a sensed well condition.

摘要： A system for selective production from, and stimulation of, subterranean production zones while improving productivity and enhancing control of the well. Portions of a production tubing string and an internal stimulation/shifter string are assembled and run together as completion segments. Consecutive completion segments, with each segment including packers that surround sleeves and terminate at the upper end in a well control valve, are run into the cased wellbore so that the acid flow ports operated by sleeve valve assemblies are placed proximate the perforations of prospective production zones. The production zones are then stimulated as the stimulation/shifter string is moved progressively outward placing acid at each consecutive zone. The stimulation/shifter string is then removed from the production tubing string, mechanically closing the well control valve assembly by tubing manipulation. A well control valve assembly prevents flow from or to completion segments further downhole from the well control valve assembly once the stimulation/shifter string has been removed from the production tubing string. The well control valve assembly features a shaped flapper plate which, when opened, conforms closely to the shape and size of the production tubing string's interior diameter. The flapper plate is biased toward a closed position by a compression spring arrangement that includes an arm which levers the plate upward toward a seating surface. The valve assembly's closure is mechanically induced and is not responsive to a sensed well condition. Reopening of the valve assembly is accomplished by insertion into the assembly of a tubular member, or "stinger", which is incorporated into a running arrangement. The stinger is described in relation to a seal assembly which is capable of reopening the well control valve and securing it in the open position. The seal assembly is incorporated into a running arrangement and inserted into the valve assembly to open the valve assembly and seal the connection between the seal assembly and the well control valve assembly.

摘要： A well safety valve, connectable in a tubing string for controlling fluid flow therethrough, in which the valve closure means is operated by a longitudinally movable, telescoping tubular operating member. High differential pressure across the closed valve closure means causes the tubular operator to telescope preventing damage to the closure means. The telescoping tubular operator extends automatically upon release of the high differential pressure. A piston rod type equalizing valve is provided which is engageable with the tubular operator in order to reduce pressure differential across the closure means prior to closure member opening forces being applied to the closure member by the tubular operator.

摘要： An apparatus (60) and method for treating an interval of a wellbore comprises an outer tubular (62) disposed within the wellbore. A sand control screen (92) is disposed within the outer tubular (62). A slurry passageway (88) is formed between the sand control screen (92) and outer tubular (62). In addition, a production pathway (90) is formed between the sand control screen (92) and outer tubular (62). When the apparatus (60) is in an operable position, the region between the outer tubular (62) and the wellbore serves as a primary path for delivery of a fluid slurry, the production pathway (90) serves as a secondary path for delivery of the fluid slurry if the primary path becomes blocked and the slurry passageway (88) serves as a tertiary path for delivery of the fluid slurry if the primary and secondary paths become blocked.

摘要： A sleeve valve assembly featuring a cylindrical housing within which a sleeve valve is axially slidable within a radially expanded section of the housing. The radially expanded section of the housing presents an inwardly extending stop shoulder at one point along its length and an annular expansion notch at another point. The sleeve valve includes a radially projecting chamfered boss about its circumference. A portion of the sleeve valve is longitudinally slotted so as to form collets. An outwardly biased C-ring is disposed about the sleeve valve within the radially expanded section. The C-ring is initially disposed to be free to travel axially along the radially expanded section between the boss and the stop shoulder. As the sleeve valve is moved toward an open position, the boss, C-ring and stop shoulder engage each other such that the sleeve valve is releasably snagged against further axial movement toward the open position. A significant axial force upon the sleeve valve is required to effect unsnagging. Upon application of increased axial force, the collets of the sliding sleeve are forced radially inward to permit the boss to slip past the C-ring.An exemplary stimulation tool incorporating the sleeve valve assembly is described which permits acid to be selectively communicated into the surrounding formation. A stimulation tool constructed in accordance with the present invention is particularly useful for acid stimulation applications in horizontal well conduits as the snagging feature of the sleeve valve assembly provides a positive indication that lateral acid flow ports within the shifter tool have been placed adjacent complimentary flow ports in the surrounding housing.

摘要： A protective flap for a batting helmet. The protective flap attaches to a batting helmet or is fabricated with the helmet, and extends alongside the cheek and jaw of the batter. The protective flap can attach to the ear cover of the batting helmet, and extends forwardly to an outer end approximately aligned with the front of the batter's chin or nose. The upper edge of the protective flap is spaced below the visor of the helmet to allow substantially unobstructed vision but this spacing is less than the diameter of the ball in play, to prevent the ball from striking the batter's cheek or eye.

摘要： A gravel packing apparatus comprises multiple joints each having substantially the same construction and each having a perforated outer tubular (150, 152) positioned around a sand control screen (154, 156) including a slurry passageway (190, 194) and a production pathway (188, 192) therebetween. First and second transition members (210, 204) are disposed at opposite ends of each joint. When two such joints are connected together, the second transition member (204) of one joint is proximate the first transition member (210) of the next joint such that a fluid traveling from the slurry passageway (190) of one joint to the slurry passageway (194) of the next joint travels from the exterior to the interior of the second transition member (204) of the one joint and from the interior to the exterior of the first transition member (210) of the next joint.

摘要： A well completion system, including a packer and a lower signal line connector carried on tubing below the packer. An upper signal line connector is carried on an upper tubing section. The upper tubing is adapted for lowering through the packer into sealing contact with the lower tubing and for operatively connecting the upper signal line connector to the lower signal line connector. A lug on the upper tubing and a profile in the lower tubing interact to rotate the upper connector into alignment with the lower connector. An upper signal line extends from a surface location down the upper tubing to the upper connector. A lower signal line extends from the lower connector down the lower tubing to downhole sensors and/or actuators.
