The present invention provides a device, namely a hydraulic-mechanical pipe connector that allows a simple, user friendly way to attach pipe and tools to one another whether this is a single connection to a bottom hole assembly or a splice connection joining two pipe ends together, thereby eliminating the need for tools such as wrenches and tongs and removing the need and difficulty of requiring pipe rotation to make up the connection. It also provides a simple, safe and efficient manner to affix a tool, sub assembly, bottom hole assembly or similar oil tools to the end of a pipe that has no thread attachment, without the need for the hand tools and wrenches. More importantly, the present invention provides a device that can splice multiple pipe or coil sizes together using the hydraulic actuation technique.

This invention relates to a manipulation tool and method for connection and operation of a controllable well device and adapter. The tool includes an elongated housing with first and second end portions, a gripping device in the first end portion provides releasable engagement with the well device controllable by means of the manipulation tool. The gripping device includes means for resisting rotational and axial movement between the housing and the well device. At least one manipulation device is axially displaceable between a first and second position along a longitudinal axis of the housing and rotatable around the longitudinal axis of the housing. A first driving device produces axial displacement of the at least one manipulation device, and a second driving device produces rotation of at least one manipulation device. The first and second driving devices are connected to a control unit for controlling energy to the driving devices.

The present disclosure relates to an innovative retrieval device designed for the efficient recovery of items from deep wells, plumbing pipes, and similar structures. The device features a body with a plurality of arms attached to its distal end, each arm equipped with specialized gripping features to securely capture and retrieve items. A control cable is connected to the arms, facilitating their movement from an open to a closed position for item capture. The inclusion of a camera device within the body aids in precise item location, while a resilient connecting device allows for adjustment to the retrieval depth through an additional cable at any desired depth. Enhanced functionality is introduced through optional features such as a body tube for length extension, skids for improved navigation within pipes, and different cable configurations for optimized arm closure.

Examples of methods and systems are disclosed. The systems may include an overshot including a tubular housing comprising a bore and configured to transfer a fluid flow through the bore. The overshot may also include a rotatable housing extending in a direction of a central axis of the tubular housing. The rotatable housing may be configured to receive the fluid flow and be driven by the fluid flow to have rotational motion about the central axis. The rotatable housing may be also configured to receive a fish and rotate and displace the fish towards the tubular housing. The overshot may further include a gripping mechanism disposed within the bore and configured to receive and engage with the rotated fish. The overshot may still further include a bearing disposed between the tubular housing and the rotatable housing and configured to decouple rotational motion of the rotatable housing and the tubular housing.

A method includes conveying a sacrificial tool into a wellbore on a conveyance, the wellbore penetrating one or more subterranean formations and the sacrificial tool including an overshot fishing tool, a tubing operatively coupled to and extending from the overshot fishing tool, and a liner hanger arranged at an upper end of the tubing. An uphole end of a downhole tool is received within with the overshot fishing tool, the downhole tool being stuck in the wellbore adjacent the one or more subterranean formations. The uphole end of the downhole tool is sealingly engaged, and a cement is subsequently circulated through the sacrificial tool and the downhole tool and discharged into an annulus defined between the downhole tool and an inner wall of the wellbore.
