Abstract:
A described bottom hole assembly includes a drill bit arranged at a distal end of a drill string and rotatable about a first central axis, the drill bit exhibiting a first unbalance force acting laterally on the drill bit at a first angular orientation, a first unbalance force marking physically applied to the drill bit and corresponding to the first unbalance force, a tool arranged axially from the drill bit, the tool exhibiting a second unbalance force acting laterally on the tool at a second angular orientation, and a second unbalance force marking physically applied to the tool and corresponding to the second unbalance force, wherein an angular offset between the first and second unbalance forces markings is able to be manipulated in order to obtain a minimized or desired tandem resulting unbalance force.
