Magnetic Virtual Observatory.
Reduce The Magnetic Field Uncertainty In A Cost-Effective Way
Global positioning system (GPS) signals cannot be received underground, so the oil/gas industry uses magnetic navigation while drilling boreholes to reservoirs. The current state-of-the-art magnetic reference models used today cannot account for the rich spatial and rapid temporal variations of the external magnetic field. These variations are among the largest sources of error for directional drilling companies.
Measuring local magnetic fields using magnetometers can be prohibitively expensive or practically impossible. Flatiron’s Virtual Observatory (VirtualOBS) technology will drastically reduce the magnetic field uncertainty in a cost-effective way. VirtualOBS combines a global model which provides the large-scale behavior of the external magnetic field to real-time measurements from satellites and ground stations to provide local corrections to the global model.
