Scientific Drilling’s Lodestone active ranging system is an innovative long distance at bit ranging solution that is ideal for precision wellbore placement and intentional wel lbore intersections.This industry leading magnetic ranging tool can operate with any directional drilling configuration and operates independently from the MWD system in the bottom hole assembly.

Provides relative ranging measurements at the bit, so steering decisions can be made with greater confidence sooner
Proven to generate accurate and consistent ranging results in both cased and open hole wells, eliminating the need to compromise completions with non-magnetic or fiberglass casing joints
Ranging data allows for the deviation of the drilling well in order to intersect (or avoid collision with) a cased well
Compact bit sub design (16”) reduces wear and tear on mud motor/rotary steerable drive shafts and minimizes negative build up rate effects
Proven to provide the greatest detection range on the market at 420’/128m
