Abstract
The drilling assembly includes an eccentric adjustable diameter blade stabilizer, having a housing with a fixed stabilizer blade and a pair of adjustable stabilizer blades, and a bi-center bit, having an eccentric reamer section and a pilot bit, mounted on the eccentric stabilizer. The stabilizer and bit have an alignment mechanism for aligning the fixed blade with the reamer section. The alignment mechanism includes an aperture on the bit which is aligned with an aperture on the stabilizer as the stabilizer is made up on the bit. An alignment member is received by the aligned apertures for maintaining the alignment.
