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.

Ratcheting spanner

An apparatus for debris removal. The apparatus includes a debris storage housing. The debris storage housing has a velocity tube located therein. The velocity tube has a hole formed therethrough. A diverter is located on the velocity tube adjacent the hole.

Apparatus, system, and methods for downhole debris collection

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.

Rotatable wireline tool of enhanced hydraulic drive consistency

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 ().

Method and system for an automatic milling operation

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.
