Abstract
A method and system is disclosed for interactively displaying estimated stability of rock surrounding a wellbore. The display shows a three-dimensional representation of the orientation of a portion of the wellbore and the associated estimation of stability of the rock surrounding the wellbore. The user can alter the orientation of the portion of the wellbore, after which in real time the stability estimation is recalculated and redisplayed. The method and system can be used for planning or modifying a well plan, either before or during the drilling process. The method and system can also be used for diagnosis of stability problems. The method and system can also be used for displaying and analyzing the estimated stability of perforations surrounding a wellbore and for planning and arranging such perforations.
