1. A drilling system comprising:
a drillstring comprising a bottom hole assembly at one end of the drillstring for drilling a well;
a computing system comprising at least one processor and at least one memory unit, the computing system configured to:
prior to commencing drilling, receive a directional drilling well plan for the well, the well plan comprising:
a set of instructions to reach a target location for the well using the drilling system; and
a planned trajectory to reach the target location;
receive bottom hole assembly position data from one or more sensors during construction of the well, the bottom hole assembly position data comprising one or more of survey data for the bottom hole assembly and continuous position data for the bottom hole assembly;
determine a current position of the bottom hole assembly using the bottom hole assembly position data;
compare the current position of the bottom hole assembly to the planned trajectory;
in response to determining that the current position of the bottom hole assembly is off the planned trajectory by a threshold amount:
receiving, from a user, an intermediate target;
creating a candidate correctional trajectory that passes through the intermediate target specified by the user, the candidate correctional trajectory further comprising one or more drilling parameters to reach the intermediate target;
presenting the one or more drilling parameters for the candidate correctional trajectory to the user in editable format;
in response to receiving one or more edits to the one or more drilling parameters for the candidate correctional trajectory, calculating an updated position for the intermediate target using the edited drilling parameters and displaying the updated position to the user;
providing the user an option to select the candidate correctional trajectory; and
updating the well plan using the selected candidate correctional trajectory.
