Appl. No.:

09/689121

Inventors:

Carl W. Stoesz - Katy TX

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 31107

US Classification:

166301, 166 50, 1661776, 166178

Abstract:

A method for using fishing and drilling jars which require high applied tensile loads in deviated or horizontal well bores is described. The method involves the placement of the string of high frequency vibratory devices that are triggered by flow therethrough. These vibratory devices are placed in the region of the bend or deviation in the well bore. The vibratory forces are applied coincidently with the tensile overpull force so as to fully utilize the applied overpull force at the surface down hole at the jar which is attached to the fish.

International Classification:

E21B 31107

US Classification:

166178, 166237, 166301, 175296

Abstract:

A bi-directional jar with bit turning capability jars down when weight is set down on the tool and pressure is built up on a piston to move the body up while compressing a spring. When spring force opens the valve in the piston, the housing comes down striking an anvil as the flow rushes through the piston before the valve recluses for another cycle. The valve member features a hydraulic brake to slow its movement after the valve is forced open. Clutching action comes from an angled spline acting through a spirally cut cylinder, which reduces in diameter to engage the bit to turn. A single spring acts on a pair of pistons for bi-directional jarring. Modularity allows rapid conversion to uni-directional operation.

Abstract:

A method of removing a gravel packed screen to reach another zone is described. The method involves a bottom hole assembly comprising an isolation device for the screen and a tool to latch on to it. A perforating gun is shot off to put holes in the screen to allow gravel to come through. A flow through a reversing valve is initiated to urge the gravel into the newly perforated screen while a vibrator shakes the screen and stimulates gravel flow through the screen. Alternatively, the screen is not isolated and a reverse circulation from the surface in conjunction with vibration urges the gravel to flow through the screen and out through the tubing supporting the bottom hole assembly.

International Classification:

E21B007/00

US Classification:

173 1, 173 90, 173 91, 173136

Abstract:

A downhole vibration tool consisting of a body assembly installed in a work string, and a drop-in dart valve assembly. An open inner bore through the body assembly allows the performance of operations through the body assembly. To activate the vibration tool, the dart valve assembly is dropped into the work string and pumped downhole into engagement with the body assembly. Once the dart valve assembly is in place in the body assembly, continued pumping of fluid will cause the tool to begin to vibrate longitudinally. When the jarring operation is finished, the dart valve assembly can be released from the body assembly and retrieved, with a wireline or coiled tubing unit.

US Classification:

166318, 1662426, 285 3

Abstract:

Devices and methods for releasably securing components of a device having a sliding sleeve arrangement to prevent premature actuation due to vibration. In a currently preferred embodiment, standard elastomeric O-rings are used as shear members. The O-ring shear members reside within spaces formed between two slidable sleeve members. The O-rings are sheared cross-sectionally to allow the sleeve members to move axially with respect to one another. An exemplary coiled tubing shear release joint is described that incorporates a shear disconnect assembly which uses elastomeric O-rings as shear members. Multiple O-ring seals can be used as shear members to increase the shear value of the device. The use of O-rings as shear members helps prevent premature sliding of sleeve components in response to high vibration. Because the O-rings are resilient, they absorb vibration and do not shear during vibration, the connection between the two sleeve components will not be released prematurely.

US Classification:

166301, 1661772, 1661776

Abstract:

An apparatus for applying a force to a stuck object in a wellbore that includes a work string extending in the wellbore is provided. A vibrating string has a vibrator engaged with the stuck object. The vibrator drives the vibrating string to impart the force to the stuck object. An isolator associated with the work string and the vibrating string decouples a portion of a motion of the vibrating string from the work string. A method of applying a force to a stuck object in a wellbore is provided that includes comprises extending a work string in the wellbore from a surface location. A vibrating string is engaged with the stuck object. The vibrating string is driven at a frequency to apply the force to the stuck object. The work string is isolated from the vibrating string such that a portion of the motion of the vibrating string is decoupled from the work string.

Abstract:

A system for inserting control lines to a control line receptacle at an alternate path structure including an upper guide having a path structure engagement roller, a control line insertion wheel and a control line bypass space. The system further includes a lower guide separate from the upper guide and having a path structure engagement roller and a control line insertion wheel. The path structure engagement roller and control line insertion wheel are resiliently biased to a position to cause control line insertion to the alternate flow path structure when in an engaged position.
