MagCUBE is unveiled to enhance geomagnetic referencing. It’s designed to increase measurement-while-drilling accuracy in directional drilling.
The new technology utilizes magnetic intensity measured at the surface from an airborne, marine, or land magnetic survey. Surface magnetic data are geomagnetically referenced to the magnetic survey data measured in the wellbore. This provides a finer subsurface anomaly vector which gives a more accurate well path to avoid costly side tracks.
Geomagnetic referencing — when enhanced with MagCUBE — can reportedly lead to significant savings in overall project costs. It provides accurate, real-time data on well position while corrections to trajectory are still possible. This minimizes the need to side track. The technology also minimizes costs of extra rig time required to run a post-drilled gyroscopic survey.
