Abstract
A method for evaluating a planned well trajectory for avoidance of collision with an existing wellbore includes constructing a bounding box about the planned well trajectory and a bounding box for a trajectory of at least one existing wellbore. If there is no intersection between the bounding boxes, the planned well trajectory is used for drilling a well.
