ABSTRACT:
Apparatus for effecting a minute change in the direction of a downhole rotary tool comprises an eccentric cylindrical surface formed on the housing of a downhole motor or a member connected between the motor and the tool, which is received within an eccentric bore of a stabilizer housing, the periphery of which snugly engages the walls of, for example, the newly drilled well bore. Selective angular adjustment of the eccentric stabilizer housing relative to the eccentric surface provided on or adjacent to the motor housing effects a desired shift in angular position of the rotary tool to effect a desired change in the direction of the selected activity, such as drilling.
