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.

Displaying steering response with uncertainty in a heat map ellipse

Methods, drilling systems, and computer-readable media for evaluating candidate correctional trajectories for a directional drilling well. If the user wishes to investigate alternatives trajectories or trajectories to get a BHA back to a planned trajectory, the computing system allows the user to enter one or more intermediate targets. The computing system generates drilling parameters for the alternative targets and displays them to the user. The user can adjust parameters and intermediate targets, as well as drilling parameters, to investigate a range of possible solutions before selecting an update to the planned trajectory.

System for drilling a directional well

A computer-implemented method including receiving a steering command identifying a tool face orientation in which the steering command is expected to produce an intended steering response of an intended drilling trajectory. The method further includes receiving an actual steering response result of the steering command in which the actual steering response result identifies an actual drilling trajectory. The method further includes storing a dataset comparing the actual steering response result in relation to the intended steering response, determining an uncertainty level of the tool face orientation based on the stored dataset, and outputting a visual representation of steering response with the uncertainty level.
