Well Trajectory Planning Using Bounding Box Scan For Anti-Collision Analysis

摘要

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.

1. A method for evaluating a planned well trajectory for avoidance of collision with an existing wellbore, comprising:
in a processor, constructing a bounding box about the planned well trajectory and a bounding box for a trajectory of at least one existing wellbore, the existing well trajectory constructed from survey data obtained from the at least one existing well; and determining in the processor if there is no intersection between the bounding boxes, and using the planned well trajectory for drilling a well if no intersection exists.
