Filed:

Dec 9, 2011

Appl. No.:

13/316239

Inventors:

Michael Jensen - Richmond TX, US
Ruben Martinez - Houston TX, US

International Classification:

E21B 29/00
E21B 34/00

US Classification:

166298, 166 557, 166316

Abstract:

A rotatable downhole cutting tool configured for enhanced drive consistency in low power circumstances. The tool is equipped with a hydraulic axial drive actuator suitable for use in wireline deployment. The actuator itself includes a reciprocating piston with a ball screw that threadably interfaces a ball nut for dampening the axial drive imparted by the piston. As such, even though hydraulically driven at generally well under about 10 horsepower, bounce in the axial drive is substantially eliminated. This is particularly advantageous where cutting is to be applied to downhole metal based obstructions.

Inventors:

Michael Thomas Jensen - Richmond TX, US

International Classification:

B25B 13/46

Abstract:

A ratcheting spanner which can be installed on a rotatable body along a vector substantially perpendicular to an axis of rotation. The ratcheting spanner comprising a spanner body, a ratchet ring, and a plurality of pawls. The pawls can rotationally couple the spanner body to the ratchet ring in one or both directions relative to the axis of rotation. The ratcheting spanner can have a home key to facilitate the alignment of the openings in the spanner body and the ratchet ring. The direction of rotational coupling of the pawls and the action of the home key can be controlled by one or more selector controls. A driven ratcheting spanner can be constructed to further allow transmission of torque to the ratchet ring without movement of the spanner body. A method of using a ratcheting spanner to rotate a rotatable body.

- Sugar Land TX, US
Michael Jensen - Richmond TX, US

International Classification:

E21B 37/00
E21B 41/00

Abstract:

A nozzle assembly including a nozzle. The nozzle has an elongated body. The elongated body has a nozzle end at one end and a connection portion at another end. A joint section is connected with the connection portion. The joint section allows the nozzle to move axially and radially when an axial force is applied to the nozzle end.

US Classification:

166311, 166 53

Abstract:

A method () and an assembly () for milling an obstruction disposed within a wellbore (W) includes a milling module () having a motor () rotating a milling bit (), a first electronics cartridge () for controlling the motor based upon a motor torque value, a tractor module () for engaging with the wellbore and providing a push force against the wellbore to urge the milling assembly in a direction of the milling bit, and a second electronics cartridge () for controlling a push force value of tractor module. The method involves rotating the milling bit () and engaging the tractor module with the wellbore (), and adjusting, iteratively, the operation () based on a calculated torque value and a calculated push force value to maintain the calculated values at around a target torque value and below a push force limit value ().
