Abstract: Disclosed herein is a method of installing an elastomeric element onto a tubular. The method includes, positioning the elastomeric element onto a radially expandable member, radially expanding the radially expandable member and the elastomeric element installed thereon, positioning a tubular coaxially with the radially expandable member, and axially urging the elastomeric element off the radially expandable member thereby allowing the elastomeric element to be positioned coaxially about an outer perimetrical surface of the tubular.

Abstract: Downhole fluid jet cutting tools having extendible and retractable arms with cutting heads on the ends are disclosed. The jet cutting tools permit casing and other downhole surfaces to be cut utilizing a cutting fluid forced through a jet nozzle assembly. Inflation of an inflatable member within the passageway of the tool moves the jet nozzle assembly when cutting fluid pressure inflates the inflatable member. As a result, a cutting head of the jet nozzle assembly is extended and cutting fluid is forced at high pressure from the passageway to the cutting head where it is expelled through nozzles for cutting casing and the like. The jet cutting tools permit the cutting head to be extended, retracted, and re-extended or redeployed multiple times without the need for being retrieved from the wellbore.

Abstract: Downhole fluid jet cutting tools having extendible and retractable arms with cutting heads on the ends are disclosed. The jet cutting tools permit casing and other downhole surfaces to be cut utilizing a cutting fluid forced through a jet nozzle assembly. Movement of a piston slidingly engaged within the passageway of the tool actuates the arms when cutting fluid pressure acts on the piston. As a result, the arms are extended and cutting fluid is forced at high pressure from the passageway to the cutting head where it is expelled through nozzles for cutting casing and the like. The jet cutting tools permit the arms to be extended, retracted, and re-extended or redeployed multiple times without the need for being retrieved from the wellbore.

Abstract: A connection to a stub downhole is accomplished in a variety of ways. A string has a tapered lower end inserted into the stub and expansion occurs from within the tapered lower end into the stub to leave a connection without reduction of the internal diameter. An overshot fitting can be lowered outside the stub and the stub expanded from within against the overshot. Both options in a single tool can be used to get sealing around the inside and the outside of the stub. An adjustable swage can be used with the overshot configuration where the overshot has an internal groove. The adjustable swage expands from within the stub into the surrounding groove in the overshot.

Abstract: Overshot fishing tools for retrieving objects, i.e., “fish” lodged within a wellbore are disclosed. The overshot fishing tool comprises a housing having a housing bore with at least one recess disposed along the inner wall surface of the housing bore. A slip is disposed within each of the recesses. Each slip has a gripping profile for engaging and securing the fish. Each slip also has a length and a width such that the slip, when actuated, provides circumferential loading on the housing. In specific embodiments, each slip includes two or more different gripping profiles to facilitate retrieval of different types and sizes of fish.

Abstract: A downhole tool for engaging a borehole wall of a well, with outwardly displacing gripping elements to engage the borehole wall in such a way as to prevent rotation of the tool relative to the borehole wall, thereby preventing a downhole motor from imposing a reactive torque on the workstring uphole from the tool. The gripping elements can have one or more rolling elements, such as wheels, to roll longitudinally along the borehole wall in either the uphole or downhole direction, or both, while preventing transmission of reactive torque to the workstring. The gripping elements can also be configured to prevent longitudinal motion of the tool, such as blades. Displacement of the gripping elements can be hydraulically actuated.
