A directional drilling tool comprising an orientation spear point having a spear axis. The orientation spear point comprises an end shaft with a threadable extension disposed along the spear axis and a support pin having a support pin axis perpendicular to and intersecting the spear axis. An orienting pin having an orienting pin axis perpendicular to the support pin axis and spear axis and intersecting the spear axis also extends through the end shaft. A latch rod with a latching edge is connected to the end shaft, and a nose is connected to the latching rod. The directional drilling tool also comprises a crossover sub comprising a first threaded section for engaging the threadable extension, and a second threaded extension for receiving a plurality of pin dimensions, an end of a tool, or a box.

Directional drilling tool

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.
