Abstract

A system and method that include receiving a drilling trajectory plan to drill an intended trajectory. The system and method also include analyzing the drilling trajectory plan and identifying a tool face orientation to drill the intended trajectory based on the drilling trajectory plan. The system and method additionally include identifying an uncertainty level associated with the tool face orientation based on a data structure storing uncertainty levels at different tool face orientations. The system and method further include determining a drilling plan based on the uncertainty level associated with the tool face orientation.
