Abstract: A system for placing a tool in a production string. The system uses a tubular connection location, like a no-go landing nipple, and a second tool driven by deformable balls. The second tool will be a work tool and may be a jar, perforation tool or other well service tool. The work tool will have a locking mandrel associated with it, and the locking mandrel will utilize a funnel, sized to seat a deformable ball. A number of different deformable balls having different characteristics may be used. Some balls may push the entire second tool to a location within the no-go landing nipple, while others may be utilized to extend locking keys from slots to lock the second tool in place. Balls may, at high pressure, be deformed such that they can pass through the funnel, allowing fluid pressure to be utilized for other tasks within the tool.

Abstract: A tool for use in a non-flow environment within a wellbore. The tool is configured to push or pull a well-service tool through the non-flow environment. The tool has one or more drivers, such as an impeller, which is driven by a motor powered by a battery or wireline. The tool may push the well-service tool up against a blockage, so that the well-service tool may clear the blockage, terminating the non-flow environment.

Abstract: A jarring tool used to dislodge a stuck tubular string or bottom hole assembly within an underground wellbore. A funnel element is placed underground either within, or as part of, a tubular string. A deformable ball may be seated within the funnel element to block fluid from passing within the tubular string. Hydraulic pressure may build within the tubular string until it exceeds the pressure the ball can withstand. This will cause the ball to deform and be expelled through the funnel element. With no ball to block its flow, fluid will be rapidly released through the funnel element. The rapid release of fluid will cause a powerful jarring or jolting to the tubular string or bottom hole assembly. Deformed balls may be captured in a cartridge chamber installed within the drill string and sized to create turbulent fluid flow within the drill string.

Abstract: A system used to dislodge and, if necessary, sever a tubular string that is stuck within a cased wellbore. The system utilizes a jar, a plurality of plugs, and a tubular severance device. Components of the system are carried to their respective desired downhole positions by downward fluid flow within the wellbore. The jar is configured to jar the string in an effort to dislodge the string from its stuck point. The plugs are configured to fill open perforations formed in the casing in order to direct the fluid toward the stuck point and away from the perforations. If the string cannot be freed by the jar, the tubular severance device is deployed within the string above the stuck point. Detonation of the device severs the string above the stuck point.

Abstract: A perforating gun for use in oil and gas operations. The gun is carried to a desired area of a wellbore using only fluid pressure. The gun comprises a charge housing disposed within a removable sleeve. The charge housing comprises a plurality of shaped charges in communication with one or more sensors. The sensors are programmed to initiate the detonation sequence of the shaped charges upon measuring set parameters. Upon detonation, the gun fragments into a plurality of pieces that may be washed away from the detonation site.

Abstract: A milling tool for use in a cased wellbore. The milling tool has a housing having a plurality of pockets formed therein. A blade is installed within each pocket and is movable between open and closed positions. The blade projects from the pocket when in an open position. Rotation of the housing causes the blades to move to an open position. The blades remain in a closed position when the housing is not rotating.

Abstract: A micro frac plug used to seal individual perforations formed in a casing installed within a subterranean wellbore. The plug comprises an insert element and a deformable sleeve. The insert element is received and retained within a medial section of the sleeve. The plug is sized to be lodged in or seated on a single perforation. The plug blocks fluid from flowing through the perforation.

Abstract: A sand removal system configured to remove sand from a casing installed within a producing wellbore. The system utilizes a bottom hole assembly comprising a check valve sub and at least one sand removal tool. A swab cup installed within a vertical section the casing is used to create a pressure differential around the bottom hole assembly, causing fluid and sand to flow at a high velocity into the sand removal tool. The sand is caused to flow upstream where is later removed from the wellbore.

Abstract: A tool for cleaning out the lower end of a cased wellbore having an installed production string. The tool is lowered down the production string until it projects from an end of the production string and into the wellbore. High pressure fluid is then sprayed from the tool's fluid openings into nearby portions of the wellbore. Once cleaning operations are complete, the tool is carried back to the ground surface using subterranean fluid pressure.

Abstract: A downhole tool configured to vary the amount of pressurized fluid delivered to other tools incorporated into a bottom hole assembly, such as a mud motor. The tool comprises an inner element installed within an outer sleeve. The inner element is configured to move between three different positions relative to the outer sleeve. In a first position, pressurized fluid is diverted away from downstream tools within the bottom hole assembly. In a second and third position, pressurized fluid is directed towards downstream tools. Movement of the tool between the different positions is caused by varying external forces applied to the tool.
