Abstract: A hydraulic jar coupled between opposing first and second portions of a downhole tool string. The hydraulic jar includes a housing comprising a shoulder protruding radially inward from an internal surface of the housing, a shaft disposed within the housing, a piston fixedly positioned about the shaft and fluidly sealed against the shoulder, and a pressure relief device. The housing and the shaft move axially relative to each other and the shoulder axially interposes first and second portions of an annulus formed between the shaft and the housing. The pressure relief device controls fluid flow from the first annulus portion to the second annulus portion based on a pressure of the fluid in the first annulus portion relative to a set pressure of the pressure relief device.

Abstract: An apparatus and method for drilling is disclosed, including a drill string with at least one jar and one reaction valve. Drilling fluid flows through the reaction valve. The reaction valve is selectively throttled, which creates a differential pressure across the valve seat. The differential pressure creates an axial force that is transferred to the jar, which aids in cocking or firing the jar. In an embodiment, a reaction valve throttles downward fluid flow to create a downward compressional force on the jar, while in another embodiment, a reaction valve throttles upward fluid flow to create an upward tensile force on the jar. Upward and downward fluid flow may be alternatively throttled for alternately firing the jar upwards and downwards. A bypass valve may be included in the drill string for establishing a drilling fluid flow path when such may be otherwise obstructed by foreign matter in the wellbore.

Abstract: A hydraulically powered fishing tool is provided for retrieving another tool or tubular stuck in a well. A tool housing is supported in a well on a work string, and the housing encloses a plurality of pistons (16, 28, 34) each movable in response to pressurized fluid transmitted through the work string. An anchor (52) axially fixes the position of the tool in the well, and a tool mandrel (40) is axially movable relative to tool housing when the anchor is set. A fishing device (82) engages the another tool or tubular, so that axial movement of the mandrel in response to the plurality of pistons dislodges the stuck tool or tubular.

Abstract: A double-acting jar comprises an inner mandrel and an outer housing. The inner mandrel is disposed telescopically within the outer housing to define a fluid chamber in between. There is an uphole restriction and a downhole restriction spaced from one another within the fluid chamber. A uphole valve is disposed within the fluid chamber, the uphole valve having a first seating surface engageable with an uphole facing sealing shoulder in the fluid chamber. The uphole valve has a first exterior surface that fits with close tolerance within the uphole restriction over at least a portion of the first exterior surface. There is a downhole valve disposed within the fluid chamber, the downhole valve having a second seating surface engageable with a downhole facing sealing shoulder in the fluid chamber. The downhole valve has a second exterior surface that fits with close tolerance within the downhole restriction over at least a portion of the first exterior surface. There are first jarring surfaces on the inner mandrel and outer housing respectively for jarring contact with each other during an upjar, and second jarring surfaces on the inner mandrel and outer housing respectively for jarring contact with each other during downjar. The uphole restriction and downhole restriction are separated such that when the downhole restriction slides upward over the initial portion of the downhole valve to seat the downhole valve, at least a portion of the uphole restriction extends upwardly beyond the downhole end of the uphole valve sufficient to allow a downjar to be carried out. The uphole restriction and downhole restriction are also separated such that when the uphole restriction slides downward over the initial portion of the uphole valve to seat the uphole valve, at least a portion of the downhole restriction extends downwardly beyond the uphole end of the downhole valve sufficient to allow an upjar to be carried out.

Abstract: An arrangement by a hydraulic jar device, especially for use in underground wells, where the jar device is installed in a pipe string led down into the well, and designed so that e.g. a stuck object in the well may be loosened or broken up by upward or downward percussions from the jar device. The jar device is actuated by increasing the flow of drill fluid. Alternatively, the device is actuated by compression. A valve (27, 37, 38) closes off the flow of drill fluid, whereby a percussion cycle is initiated. The valve is designed so as also to seal during strong lateral accelerations.
