A variable offset bearing assembly, associated with an offset shaft, having a longitudinal axis, disposed with a housing, having a longitudinal axis, the assembly including a radial bearing associated with the offset shaft; a thrust bearing associated with the offset shaft; the radial bearing and thrust bearing permit axial misalignment between the longitudinal axes of the offset shaft and the housing; and the thrust bearing and radial bearing manage axial and radial misalignment of the radial bearing and thrust bearing within the housing, caused by an axial or radial force exerted upon the housing and offset shaft.

Drilling system, biasing mechanism and method for directionally drilling a borehole

A method for directionally drilling a portion of a borehole, comprising utilizing a drilling system associated with a drill string and a drill bit; rotating the drill string and placing an axial load on the drill string causing the drill string to move into compression; and stopping rotation of the drill string and with the drill string in compression, drilling a portion of the portion of the borehole while actively managing a toolface angle of the drill bit.

A drilling system for directional drilling of a borehole includes a biasing mechanism having a pivot associated with a lower bearing assembly, an offset mechanism associated with an upper radial bearing assembly, and a toolface controller, whereby the angular relationship of a drill bit and its toolface angle may be actively managed.
