Active Magnetic Ranging
Advanced 3D electrostatic finite element modeling software is used to simulate and predict the behavior of both downhole and surface injected electrical current. These models can be configured to any well geometry allowing for a detailed evaluation of ranging feasibility for complicated ranging situations such as breaks in the casing, nearby wells, end-of-pipe effects, as well as multi-layered formation resistivity.
Passive Magnetic Ranging
Custom finite element modeling software is used to estimate a distance and direction to a target wellbore using raw accelerometer and magnetometer data such as that obtained using MWD or similar surveying instruments. These models can be used for well intersection applications or to provide an estimate of another well's proximity for anti-collision purposes.
