The application of the newly developed well planning and visualization tool will reduce time the iterative process takes, from hours and days to just several minutes. The advanced visualization tool will aid wellbore construction by providing well planners...

... and strain, respectively (after Johannesen et al., 2012 ). Both have a large range of applications, but accessibility has often been a limiting factor due to large data amounts and slow data transfer rates (e.g., Schuberth, 2020, and Schuberth et al., 2021 ). For the Johan Sverdrup asset, Equinor has...
