Apparatus for reducing torque on a drill string includes a first bearing assembly, a second bearing assembly, and a bearing sleeve. The first and second bearing assemblies are disposed on and clamped onto a tubular portion of a drill pipe of the drill string, and each include a first and second section. The bearing sleeve is disposed on the drill pipe such that the bearing sleeve is maintained in an axial position relative to the drill pipe by the first bearing assembly and the second bearing assembly. Each of the first and second bearing assemblies have a first diameter portion and a second diameter portion that is smaller than the first diameter portion. The second diameter portion of the first bearing assembly and the second diameter portion of the second bearing assembly are disposed adjacent to each other and the bearing sleeve is disposed around the adjacent second diameter portions.

Apparatus and method for reducing torque on a drill string

A hydraulic connector to provide a fluidic connection between a fluid supply and a downhole tubular, the connector comprising: a body; an engagement assembly comprising an extendable portion selectively extendable from the body, the engagement assembly being configured to extend and retract a seal assembly disposed at a distal end of the extendable portion into and from a proximal end of the downhole tubular; and a valve assembly operable between an open position and a closed position, the valve assembly being configured to: allow a fluid to communicate between the fluid supply and the downhole tubular through the seal assembly when in the open position; and prevent fluid communication between the fluid supply and the downhole tubular when in the closed position.

Downhole tubular connector

A drillable, anti-rotation device for limiting the rotation of a downhole tool, such as a cement plug, when drilling out the down hole tool. The drillable, anti-rotation device comprises a drillable sleeve connected within a non-drillable outer tubular member connected within a pipe string. The sleeve has one or more grooves or other indentations, and/or one or more ribs or other protrusions extending inwardly within the interior of the device for gripping or otherwise retarding the rotation of such downhole tool.
