Abstract
A bottom hole assembly for drilling a well, comprising a non-magnetic tubing, an orienter, a motor, a bit fed with drilling fluid which passes through the non-magnetic tubing, and a sensor package contained within the non-magnetic tubing, characterized by a drilling fluid flow tube passing through the non-magnetic tubing adjacent to the sensor package, and means for determining the relative position measurement between the non-magnetic tubing and the motor.
