A setting kit for connecting a plug to a setting tool includes a collet connecting part configured to be attached to an internal sleeve of the setting tool; and a collet configured to be attached with a first end to the collet connecting part and with a second end to the plug. The second end automatically connects to the plug by only pushing the second end onto the plug.

Quick connect setting kit and method

A sub connects a gun string to a hydraulically activated setting tool for setting an auxiliary tool in a well. The sub includes a housing that prevents a well fluid from entering inside the housing; a plug that covers a hole made in a wall of the housing; and an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between an outside and the inside of the sub.

Hydraulically activated setting tool and method

A setting tool () for setting a plug in a well, the setting tool () including a body () extending along a longitudinal axis X; a rod () extending along the longitudinal axis of the body (), from an upstream end (B) to a downstream end (A) of the body (); a chamber () formed at the downstream end (A) of the body; and a restriction element () located in the chamber (). The rod () extends through the entire chamber () and the restriction element () is located between the rod () and a wall (A) of the chamber ().

Device and method for retrieving a restriction element from a well

A downhole isolation system for sealing a well, the downhole isolation system including a setting tool having an internal chamber; a first restriction element placed within the internal chamber; and a second restriction element placed within the internal chamber, separate from the first restriction element.

Two-part restriction element for large-bore downhole isolation tool and method

A downhole tool for connecting an interior of a casing to a formation, the downhole tool including an inner housing extending along a longitudinal axis X; an outer housing that encloses the inner housing and forms first and second chambers; a piston that separates the first and second chambers; a port that fluidly communicates an outside and inside of the downhole tool; and a stopping mechanism that prevents the piston from opening the port. The piston interrupts the fluid communication between the outside and inside the downhole tool.

Device and method for opening and stopping a toe valve

A downhole tool for connecting an interior of a casing to a formation, the downhole tool including an inner housing extending along a longitudinal axis X; an outer housing that encloses the inner housing and forms first to fourth chambers; a first piston that separates the first and second chambers; a second piston that separates the third and fourth chambers; a port that is configured to fluidly communicate an outside and inside of the downhole tool; and a stopping mechanism that prevents the second piston from opening the port. The second piston is positioned to separate the port into an outer portion and an inner portion to interrupt a fluid communication between the outside and inside of the downhole tool.

A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.

Wellbore plug isolation system and method

An air lock device for sealing a casing located inside a well, the air lock device including a body having a bore and configured to be attached with each end to the casing; a moving element located inside the bore; and a blocking element connected to the moving element, the blocking element preventing a fluid to pass through the bore of the body. The moving element forms an inner chamber with the body in which the blocking element is trapped after the blocking element is punctured by the moving element.

Debris preventing downhole air lock device and method

A setting tool for setting an auxiliary tool in a well includes a housing having a floating piston that separates a pressure chamber from a hydraulic chamber; and a plug that is removably located in a through passage of the floating piston. The through passage fluidly connects the pressure chamber to the hydraulic chamber, and the plug prevents a fluid to move from the pressure chamber to the hydraulic chamber or from the hydraulic chamber to the pressure chamber when attached to the floating piston.

Self-bleeding setting tool and method

A hydraulically activated setting tool for setting an auxiliary tool in a well, the setting tool including a housing that prevents a well fluid from entering inside the housing; a floating piston placed inside the housing and closing an end of a pressure chamber; an attached piston placed inside the housing and configured to actuate the auxiliary tool; a fluid chamber located between the floating piston and the attached piston, wherein the fluid chamber holds a fluid; and a communication element configured to establish a fluid communication between an outside and an inside of the housing. The fluid communication makes a well fluid in the well to directly act on the floating piston.

A catch-and-release tool conveyed with a well casing for use in a wellbore comprising an outer housing having flow ports therethrough, a functioning apparatus disposed within the outer housing comprising a movable member/sleeve and a holding device, and a blocking apparatus comprising a blocking member configured to block the flow ports in a first position. When a ball deployed into the well casing passes through the tool in a downstream direction and moves back in an upstream direction, the restriction element engages onto the holding device and moves the movable member such that a port is exposed to up hold pressure and the blocking member travels to a second position in a reverse direction unblocking flow ports and enabling fluid communication to the wellbore. The ball is thereafter released in an upstream direction.

Reverse flow catch-and-release tool and method

A time delay tool and method includes a mechanical restraining element, a reservoir for containing a reactive fluid, an actuating device and a wellbore device. When a stored energy is applied on the wellbore device, the actuation device is actuated and enables the reactive fluid in the reservoir to come in contact with the mechanical restraining element. While the mechanical restraining element undergoes a change in shape due to a chemical reaction, a stored energy applied on the wellbore device is delayed by a pre-determined time delay. The amount of the pre-determined time delay is determined by factors that include the reactive fluids, concentration of the reactive fluids, geometry and size of the mechanical restraining element.

Degradable material time delay system and method

An arming apparatus for arming a downhole tool in a wellbore casing comprising an arming member and a holding device. The arming member is disposed within an outer housing of the downhole tool and the holding device is mechanically coupled to the arming member. When a ball deployed into the wellbore casing passes through the downhole tool in a downhole direction and moves back in an uphole direction due to reverse flow, the ball engages on the holding device and functions the arming member such that a pressure actuating device in the downhole tool is armed.
