    摘要: A downhole tool that is capable of isolating communication pressure from below the set downhole tool, and is capable of being converted to a frac plug is provided. The downhole tool includes a packer with a ball seat defined therein. A plug is disposed at a lower end of the downhole tool to isolate the upper well from the lower well. A sealing ball is carried with the packer into the well by a setting tool. The movement of the sealing ball away from the ball seat is limited by isolation of the sealing ball from the lower well. A rod is disposed through the downhole tool contacting the plug. The rod is partially disposed in the ball seat, preventing the sealing ball from sealing. When the packer is set, flow within the well is isolated, thereby allowing treatment of the well above the packer. With the application of sufficient pressure, the sealing ball applies force to the rod which shears the plug from within the tool. The tool is converted to a standard frac plug.

    摘要: A downhole tool releasing mechanism which includes a collet for releasably engaging a mandrel of a downhole tool. A retaining band is circumferentially disposed about the fingers of the collet for maintaining engagement of the collet and the mandrel prior to application of a predetermined axially directed force on the releasing mechanism. Upon application of such a force the collet fingers expand, breaking the shear band, the mandrel is released and the downhole tool is disengaged.

    摘要: A downhole tool for use in a well has a mandrel with an expandable sealing element disposed thereabout. The mandrel has a head portion threadedly connected thereto. A shoulder in the head portion and an upper end of the mandrel define an annular space. A sleeve with a bore therethrough may be positioned in the annular space. The head portion may be removed and a solid plug installed so that it fits within the annular space and so that the downhole tool will act as a bridge plug. The downhole tool has slip rings made up of a plurality of individual slip segments that are adhesively bonded to one another at the sides thereof.

    摘要: Integrated drilling and evaluation systems and methods for drilling, logging and testing wells are provided. The drilling and evaluation systems are basically comprised of a drill string, a drill bit carried on a lower end of the drill string for drilling a well bore, logging while drilling means included in the drill string for identifying subsurface zones or formations of interest, packer means carried on the drill string above the drill bit for sealing a zone or formation of interest below the packer means, and a fluid testing means included in the drill string for controlling the flow of well fluid from the zone or formation of interest into the drill string. The drilling and evaluation systems and methods for using the systems allow one or more subsurface zones or formations of interest in a well to be drilled, logged and tested without the necessity of removing the drill string from the well.

    摘要: An improved mechanical system selectively locks the tester valve of an annulus pressure responsive tester valve in position for an indeterminate number of well annulus pressure cycles. The tester valve can be closed upon demand. The forces which accomplish opening of the ball valve act across a power piston, but the forces which close the valve act across an actuating piston. The tester valve can be run into a well with an operating element of the tester valve in a first position, such as a closed position. Upon reaching the desired depth within the well and setting of an associated packer system, well annulus pressure is then increased to a first level above hydrostatic pressure to move the power piston and thus move the tester valve to an open position. During a normal mode of operation, well annulus pressure can be cycled between hydrostatic pressure and the first level to open and close the tester valve. A fluid transfer assembly is included within the power piston which is operable to transfer fluid across the power piston. The tester valve also features a multi-range metering cartridge which is operable to meter fluid over a wide range of differential pressures.
