Abstract
A system and method for determining uncertainty of a wellbore orientation is disclosed. The system and method obtains a measurement related to a first orientation of a drill string at a measurement device. Based on the first orientation and drilling settings, the system and method predict a second orientation. A probability of the second orientation being within a predetermined area is also obtained. As a result of this information, an action may be taken, such as, skipping a planned static survey, obtaining a static survey prior to the plan, or changing a drilling setting.
