A concentric flow valve for a dual zone completion tool includes an upper seal bore sleeve, lower inner sleeve, ported sub, opening sleeve, and piston positioned within an outer sub. The upper seal bore sleeve, ported sub, and outer sub define an upper flow bore, and the lower inner sleeve, ported sub, and outer sub define a lower flow bore. The ported sub includes an upper ported sleeve coupled to the upper seal bore sleeve and a lower ported sleeve coupled to the lower inner sleeve, each ported sleeve including a valve port selectively fluidly coupling the respective flow bore to a valve flow path defined by the opening sleeve and ported sub, such that the upper and lower seal bores are fluidly coupled when the opening sleeve is in an open position. The piston is mechanically coupled to the opening sleeve and defines an opening chamber.

Concentric flow valve

A chemical injection system for controlling injection of an injection fluid from an injection fluid supply at a surface location into a production tubing assembly having an upper flow path, a first flow zone, and a second flow zone. The chemical injection system comprises a first fluid injection line configured to inject the injection fluid into the first flow zone and a second fluid injection line configured to inject the injection fluid into the second flow zone. A main fluid supply line is configured to fluidly connect both the first fluid injection line and the second fluid injection line to the injection fluid supply.

Method and apparatus for injecting fluid in a wellbore

A selectively communicatable hydraulic nipple is provided which includes an upper and lower communications component adapted to communicate with tools landed inside the hydraulic nipple. Each communications component communicates with a control line used by the hydraulic nipple. An operator is allowed to selectively communicate with tools landed inside the nipple via the upper and lower communications components via the nipple control line. As a result, should the TRSCSSV control line loose integrity, the operator has the option of utilizing the nipple control line to continue oil and gas production without the need for well modifications. Alternatively, an operator could land a chemical injection tool, with an injection string suspended therefrom, in the nipple and inject chemicals into the well via the nipple control line.

System and method for selectively communicatable hydraulic nipples

A hydraulic sleeve valve that includes a valve position indication system that provides an indication that the valve has reached a predetermined position, such as, for example, the fully opened or fully closed condition. The hydraulic sleeve valve may include a bypass relief system and may also provide a valve control fluid circulation function to filter or otherwise manipulate the control fluid.

Hydraulic sleeve valve with position indication, alignment, and bypass

An isolation system for an oil and gas well is described wherein the system comprises an isolation section and a first isolation device integral with the section and a second isolation device sealingly engaged to the section. The first isolation device may be a pressure-actuated valve and the second isolation device may be a plug.

Isolation system comprising a plug and a circulation valve and method of use

An isolation system for producing oil and gas from one or more formation zones and methods of use are provided comprising one or more pressure activated and tool shiftable valve assemblies. The tool shiftable valve may be actuated before or after actuation of the pressure activated valve.

System and method for downhole operation using pressure activated and sleeve valve assembly

A hydraulic sleeve valve is disclosed that comprises a bypass relief system that provides an indication that the valve has reached a predetermined position, such as, for example, the fully opened or fully closed condition. The bypass relief may also provide a valve control fluid circulation function to filter or otherwise manipulate the control fluid. Also disclosed are flow port alignment systems that maintain the valve flow ports in predetermined relationships.

A mechanical flow control device is provided that allows flow of production fluids along an annular path and across an valve body. A sliding sealing member can be mechanically transitioned between an opened flow position and a closed flow position as desired. The mechanical flow control device may be combined with one or more interventionless flow control devices.

Reclosable mechanical annular flow valve

An improved well completion system for completing two or more separate production zones in a well bore during a single downhole trip is disclosed. The improved completion system comprises a completion assembly comprising two or more production zone assemblies and a completion tool assembly. Each production zone assembly may comprise an automatic system locating assembly and at least two inverted seal systems for sealing against the tool assembly.

Multi-zone, single trip well completion system and methods of use

A combination jarring tool and disconnect device is disclosed in which the jarring events may be followed by separate disconnect event, or in which the jarring events may coincide with disconnect events. The tool generally comprises a housing and a sleeve in concentric arrangement and a disconnect interface. A plurality of axial and rotational locks is used to prevent premature energization of the jarring and disconnect events.

Combination jar and disconnect tool

A well system comprising an improved cross-over tool is provided. The tool may comprise a debris shield for substantially preventing sand, proppant or other well debris from fouling a flow port closing sleeve located below the cross-over tool fracture ports; a return port cover adapted to close or open a return port upon contact with a designated downhole surface regardless of tubing movement caused by stretching or contracting under stress or other induced pipe movement from downhole conditions; or a collet-type circulation valve adapted to mechanically indicate the position or flow status of the cross-over tool.

Cross-over tool

An isolation string having an upper packer and an isolation pipe in mechanical communication with the upper packer, the isolation pipe comprises an operable valve and an object activated valve. An object holding service tool is adapted to release an object to activate the object activated valve. A method of running-in an isolation string, comprising an operable valve and an object activated valve, with an object holding service tool having an object held therewith; setting the isolation string in the casing adjacent perforations; pressurizing the object to cause a release from the object holding service tool, whereby the object travels to the object activated valve; closing the object activated valve with the released object; and withdrawing the object holding service tool from the well.

Washpipeless isolation strings and methods for isolation with object holding service tool

A valve with the following components: a pipe; an inner sub connected to the pipe; an outer sub connected to the pipe, wherein the inner and outer subs are concentric and define a sub annulus; a conduit between the sub annulus and an inside diameter of the inner sub; a sleeve slideably positioned within the pipe such that in at least one position the sleeve closes the conduit, wherein the sleeve comprises a section of relatively larger outside diameter and a section of relatively smaller outside diameter which define a pressure area on the sleeve between the diameters; and a lock of the sleeve in a position which closes the conduit. A method for controlling fluid flow through a conduit between an annulus defined by inner and outer subs and an interior of the inner sub, the method having several steps: unlocking a sleeve positioned within the inner sub in a first closure position relative to the conduit by sliding the sleeve from the first closure position to a second closure position relative to the conduit; and opening the conduit by sliding the sleeve from the second closure position to an open position relative to the conduit.

Double-pin radial flow valve

An isolation system for producing oil and gas from one or more formation zones and methods of use are provided comprising one or more pressure activated valve and one or more tool shiftable valve. The tool shiftable valve may be actuated before or after actuation of the pressure activated valve.
