Abstract
A method for steering a steerable mud motor while attached to a retrievable replaceable measurement while drilling device comprising: securing a directional drilling tool to a retrievable replaceable measurement while drilling device, orienting the retrievable replaceable measurement while drilling device with a spear axis of an orientation spear point of the directional drilling tool, and lowering the orientation spear point into a non-magnetic drill collar above a mud motor. An orienting mule shoe stinger is attached to a gyroscopic device, which is then inserted over the orientation spear point, which orients the gyroscoping device along the spear axis, enabling steering of the mud motor while attached to the retrievable replaceable measurement while drilling device, while maintaining full retrievability of the retrievable replaceable measurement while drilling device from the well.
