Improve Drilling Accuracy Improve wellbore positioning in your directional drilling and wellbore surveying projects. MagCubeâ„¢ from CGG Multi-Physics uses local magnetic data to reduce the ellipse of uncertainty in Measurement While Drilling (MWD) surveys for planning borehole trajectory. Benefits include reduced collision risk and improved close-proximity well planning. With magnetic data from the CGG Multi-Physics multi-client data library, new aeromagnetic surveys, or public domain data, MagCube optimizes drill bit positioning for more successful results. cgg.com/magcubehttp://www.cgg.com/magcube
