Provided, in one aspect, is a ball seat release apparatus. The ball seat release apparatus, according to this embodiment, includes a shear sleeve, and a ball seat body located at least partially within the shear sleeve, a shear feature releasably coupling the ball seat body to the shear sleeve. The ball seat release apparatus according to this aspect further includes a ball seat slidingly engaged within the ball seat body, the ball seat configured to move from a first linear position to a second linear position, and further wherein a locking dog releasably couples the ball seat with the ball seat body.

Ball seat release apparatus

Provided, in one aspect, is a ball seat release apparatus. The ball seat release apparatus, according to this embodiment, includes a shear sleeve having a recess pocket and a ball seat body slidingly engaged within the shear sleeve, the ball seat body configured to move from a first linear position to a second linear position. The ball seat body further includes a longitudinal fluid passageway, a ball seat located in the longitudinal fluid passageway, one or more first fluid bypass ports coupling the longitudinal fluid passageway and an exterior of the ball seat body, the one or more first fluid bypass ports located on a first side of the ball seat, and one or more second fluid bypass ports coupling the longitudinal fluid passageway and the exterior of the ball seat body, the one or more second fluid bypass ports located on a second opposing side of the ball seat.

A liner installation system for use in a wellbore having a casing string disposed therein. The system includes a liner string having a liner hanger and a liner top and a setting tool having an expansion cone assembly and a locator cylinder. After running the liner string through the casing string such that at least the liner hanger is positioned within the wellbore casing, the setting tool is run through the casing string until the locator cylinder contacts the liner top. Thereafter, axially moving the expansion cone assembly through the liner string radially expands the liner hanger into contact with the casing string.

A cementing tool for cementing a casing in a well has an inner mandrel that defines a central flow passage and has at least one fluid port defined through a wall thereof. An outer mandrel is disposed about the inner mandrel and the inner and outer mandrels define an annular space therebetween. The outer mandrel has at least one sealing element affixed thereto. An opening sleeve is positioned in the inner mandrel and is movable from a closed position to an open position in which the fluid port is uncovered. An expansion cone is positioned in the annular space. Fluid pressure applied through the central flow passage, and the fluid port will pass into the annular space and will urge the expansion cone through the annular space which will plastically deform the outer mandrel so that sealing elements affixed to the outer mandrel engage a previously installed casing in the well to seal thereagainst.

A system of downhole communication and control is provided in methods and associated apparatus for data retrieval, monitoring and tool actuation. In a described embodiment, an item of equipment installed in a tubular string has a first communication device associated therewith. A tool conveyed into the tubular string has a second communication device therein. Communication is established between the first and second devices. Such communication may be utilized to control operation of the tool, retrieve status information regarding the item of equipment, supply power to the first device and/or identify the item of equipment to the tool.

Methods and associated apparatus for downhole data retrieval, monitoring and tool actuation

A downhole force generator includes a longitudinal force generating and transmitting assembly (including, for example, a motor and a threaded shaft that is extended and retracted by operation of the motor) adapted to be moved into a well. A controller is also adapted to be moved into the well and is connected to the longitudinal force generating and transmitting assembly. The controller includes a memory containing a program to control the longitudinal force generating and transmitting assembly to obtain at least one desired operating condition in the well. A sensor can be connected to the controller. A self-contained power source adapted to be moved into the well can also be used. A method of providing an infinitely variable linear force in an oil or gas well is a particular application for such a downhole force generator. This particular method comprises sensing in the well a parameter responsive over a continuum to changes in a selected operating condition in the well. This method further comprises actuating a microcontroller to run a predetermined program stored in the microcontroller. The program is run to obtain a specific state of the selected operating condition represented within the continuum of the sensed parameter.

Downhole force generator and method

In a subterranean well a one-trip production zone perforation and proppant fracturing operation is carried out using a workstring-supported perforation gun lowered into a casing nipple located in the production zone. Firing of the gun creates spaced apart aligned sets of perforations extending outwardly through a side wall portion of the workstring, the nipple, the surrounding cement, and into the production zone, after which the gun falls into and is retained in an underlying gun catcher portion of the workstring. While an overpull force is maintained on the workstring above the perforations, a proppant slurry is pumped down the workstring, out its sidewall perforations, and outwardly through the aligned perforation sets formed in the nipple, cement and production zone. After stimulation of the production zone, the workstring and the spent perforation gun that it retains are pulled up, with the upwardly moving workstring positioning a sliding closure device inwardly over the perforations to isolate the stimulated production zone until the well is readied for production. Illustrated alternate embodiments include the use of a low debris casing gun in place of the drop-off type perforating gun, the use of pre-formed wide wall perforations in the workstring side wall, and a one-trip perforation and production flow creating method in which the production zone stimulating step is eliminated.
