Description

JARRING TOOL

Background

[0001] The present disclosure is related in general to wellsite equipment such as oilfield surface equipment, downhole assemblies including, but not limited to, wireline conveyance accessories, wireline jarring tools, and the like.

[0002] Various operations can be performed in a well using tool strings that are run into the well on a conveyance or carrier structure such as a wireline, slickline, coiled tubing, jointed tubing, drill pipe, and so forth. In some cases, the tool strings can be stuck in the wellbore, with the well operator unable to apply sufficient tensile force through the carrier structure to free the stuck tool string.

[0003] To free a tool string that is stuck in a wellbore, a jarring tool is typically provided in the tool string. The jarring tool is able to apply an impact force that amplifies tension applied to the carrier structure. The amplified impact force is transmitted to other tools in the tool string to which the jarring tool is coupled so that the tool string can be freed.

[0004] It remains desirable to provide improvements in oilfield surface equipment and/or downhole assemblies.

Summary and Detailed Description

[0005] Referring now to Figure 1 , in an embodiment, the present disclosure comprises a jarring tool 10 that is attached as a part of a tool string 1 1 . The tool string 1 1 may comprises various tools or tool components 12 for performing formation evaluation services, pressure and sampling services, mechanical intervention services and the like for use in a wellbore (not shown) penetrating a subterranean formation of interest, as will be appreciated by those skilled in the art. The jarring tool 10 is attached to a conveyance 14 such as a wireline, a slickline, coiled tubing, or the like. While the jarring tool 10 is shown in Figure 1 as being disposed between the conveyance 14 and the tools 12 of the tool string 1 1 , in other embodiments the jarring tool 10 may be disposed at an end of the tool string 1 1 or between various components of the tool string 1 1 such as between tools 12 or the like. [0006] In an embodiment, the jarring tool 10 comprises a first portion 16 and a second portion 18 and defines between the portions 16 and 18 a jarring impact point 20, wherein the force generated by the jarring tool 10 is concentrated during operation. In an embodiment, a mass or the like is slidably disposed in either the the first portion 16 or the second portion 18 and is moved toward the impact point 20 by a suitable energy source, such as electrical, hydraulic, mechanical, or combinations thereof. In an embodiment, the first portion 16 or the second portion 18 is movable with respect to the other of the portions 16 and 18 and the impact point 20 is the interface between the portions 16 and 18. The jarring tool 10, therefore, is capable of producing an internally generated force or internal force that is repeatable. The internal force generated by the jarring tool 10 is augmented by providing a tension on the conveyance 14 such as a wireline cable or the like, wherein the cable tension increases the force generated by the jarring tool 10. At a given tension, the movement of the mass or the portions 16 or 18 to generate the jarring force may commence and the internal force may be enabled electrically, hydraulically, mechanically, or by combinations thereof, as will be appreciated by those skilled in the art. The internal force generated by the jarring tool 10 may be a fixed magnitude force as determined by the energy source within the jarring tool 10.

[0007] The second portion 18 may comprise a selector 22, which enables an operator to select a mode of operation for the jarring tool 10 prior to introduction into a wellbore, discussed in more detail below. The jarring tool 10 further comprises suitable electronics for sending and/or receiving communications, commands, and/or data during operation thereof. In an embodiment, the jarring tool 10 comprises three operational modes; a maximum force setting mode, a minimum force setting mode, and an intermediate force setting mode.

[0008] In the maximum mode, the impact force generated by the jarring tool 10 will be the internal force generated by the jarring tool 10 augmented by the highest possible activating tension in the cable 14, typically near the safe working load of the cable and according to the string 1 1 and profile of the wellbore. In an embodiment, the maximum mode is surface preset is active at all times and is failsafe. The maximum mode provides low frequency, high impact jarring forces from the jarring tool 10 and may be useful when a tool string 1 1 has already been determined to have stuck in the wellbore. The maximum mode setting determines the highest cable tension at which the jarring tool 10 will activate.

[0009] In the minimum mode, the impact force generated by the jarring tool 10 will be the internal force generated by the jarring tool 10 augmented by a cable tension that is less than the safe working load such as about 1500 to about 2000 lbs above the normal tension in the cable 14. The minimum mode provides high frequency, lower impact (with respect to the maximum mode) jarring forces from the jarring tool and may be useful to enable when sticking of the tool string 1 1 is determined to have first occurred. The minimum mode setting determines the lowest cable tension needed to activate the jarring tool 10.

[0010] In operation of the jarring tool 10 and tool string 1 1 , if low impact force is not needed or when stuck and low early impact is not enough to free the tool, then a command is sent from surface (such as by constant voltage, direct command, etc.), to disable the minimum mode operation (at which the jarring tool 1 1 is no longer able to activate at the lower setting of the minimum mode), after which the jarring tool 10 would automatically revert to the maximum mode or the high impact setting.

[0011] In an intermediate mode, if the operator of the jarring tool 10 and tool string 1 1 wishes to activate the jarring tool 10 at a lower setting than the maximum mode but higher than the minimum mode at a given cable tension, then a command is sent from the wellbore surface (such as by reversing the previous command sent to set disable minimum mode). This command re-enables the minimum mode, thereby activating the jarring tool 10 immediately at this intermediate setting. The impact force in the intermediate mode is determined by the internal force and the energy stored (the tension force) in the wireline cable and, therefore, may be advantageously commanded to create a jarring force at any cable tension between the maximum mode and the minimum mode.

[0012] Advantageously, the jarring tool of the present disclosure may be switched between the modes while in the wellbore, enabling an operator of the jarring tool 10 and tool string 1 1 various options for utilizing the jarring tool 10 to either enable movement of the tool string 1 1 when sticking has been determined to have first occurred or from unsticking the tool string 1 1 when the tool string 1 1 has already been determined to have stuck in the wellbore.

[0013] The preceding description has been presented with reference to present embodiments. Persons skilled in the art and technology to which this disclosure pertains will appreciate that alterations and changes in the described structures and methods of operation can be practiced without meaningfully departing from the principle, and scope of this present disclosure. Accordingly, the foregoing description should not be read as pertaining only to the precise structures described and shown in the accompanying drawings, but rather should be read as consistent with and as support for the following claims, which are to have their fullest and fairest scope.
