Abstract
The invention relates to a method for performing a drilling operation at a wellsite having a drilling rig configured to advance a drilling tool into a subsurface. The method steps include obtaining a well trajectory associated with a first volume, obtaining information related to a first subsurface entity associated with a second volume, using a three-dimensional relational comparison to determine that the first volume intersects the second volume to define a first intersection information, updating the well trajectory, based on the first intersection information, to obtain an updated well trajectory, and advancing the drilling tool into the subsurface based on the updated well trajectory.
