Disclosed is a rotating tool for inducing rotation, e.g., for activating and operating coil tubing tools for fishing target equipment in a bore casing of an oil well-bore. The rotating tool is connected with an end of coiled tubing reeled into the oil well-bore, and its other end is connected to a target equipment on which rotation is to be induced. The rotating tool converts linear motion in a first direction of the coiled tubing into rotation, and the rotation hence produced operates a coil tubing tool e.g., opening/closing jaws on an overshot. The rotating tool includes adjustable screws which allow the rotation resistance to be adjusted.

The present invention relates to a retrieval system for retrieving a well component, such as a plug, from a well tubular metal structure having a restriction and a top, said retrieval system comprising a tool string having a longitudinal extension and comprising a connection tool configured to connect with the well component, a force generator having a first part and a second part which is connectable with the connection tool and movable in relation to the first part for providing the axial force in the longitudinal extension, an anchoring section having at least one projectable element for anchoring the tool string, wherein the retrieval system further comprises a safety unit surrounding the tool string and having at least one wall and at least one abutment face configured to abut the restriction, said at least one projectable element abutting. Furthermore, the present invention relates to a downhole system and to a downhole well component retrieval method.

A standing valve puller is provided. The standing valve puller is configured to latch onto an engagement pin when the engagement pin is run into the standing valve puller within a wellbore, downhole. The standing valve puller generally includes a tubular housing having an upper end and a lower end. The upper end comprises a pair of pivoting arms dimensioned to receive the engagement pin, while the lower end offers a threaded connector that connects to a standing valve. When the engagement pin is lowered through a through-opening preserved within the arms, the arms pivot to latch onto the engagement pin. When the engagement pin is lowered again, the arms pivot away from the engagement pin, providing a latch and release cycle. A method of unseating a standing valve from a seating nipple in a wellbore is also provided herein

The method of providing a latch which is capable of passing a relatively short radius bend in a pipeline and then engaging a fishing neck on a service tool in a pipeline, and after the latch has engaged the service tool having the ability to pass the combination back through the relatively short radius bend in the pipeline.

An annular grappling element of a grappling tool for retrieving a downhole tool includes a body extending between a first end and a second end longitudinally opposite the first end, the body defining an inner surface extending between the first end and the second end and an outer surface also extending between the first end and the second end, herein one or more engagement members for grappling the downhole tool are formed on one of the inner surface and the outer surface of the body, and wherein the body is formed from a base material having a nickel content that is equal to or greater than 0.60 percent by weight (Wt %) and a carbon content that is equal to or less than 0.20 Wt %.

A tool has an elongated body having an outer surface, a first recess formed at a first axial position along the outer surface, and a second recess formed at a second axial position along the outer surface. The tool also includes a gripping element that has a plurality of collets at a gripping portion of the gripping element and a retention end. A retention mechanism axially retains the retention end of the gripping element within an axial length along the body to allow the plurality of collets to overlap with the first axial position and the second axial position of the body.

The present invention is a retrievable back pressure valve device and method of using the same that may be placed in tubing during well completion and retrieved as desired by dropping a ball down hole, which then interacts with the valve to shear the positioning points allowing for retrieval as the valve is allowed to move up the well to be removed from same.
