ABSTRACT:
A method is presented for designing a bottomhole assembly whose tendency to build/drop or hold angle is independent of borehole inclination. This method comprises the adjustment of the location of any one of the first three stabilizers of an arbitrarily selected bottomhole assembly while the location of the remaining stabilizers is left in position. In accordance with the present invention, at one particular location of the stabilizer which has been selected to be moved, the resulting build/drop or hold rate of the bottomhole assembly is independent of borehole inclination.
