1. An apparatus comprising:
a supervisory control system installable in association with a well construction rig, wherein the well construction rig is operable to perform well construction operations to construct a planned well at a wellsite, and wherein the supervisory control system comprises:
a supervisory controller communicatively connectable with a rig control system of the well construction rig, wherein the rig control system is communicatively connected with and operable to control well construction equipment of the well construction rig, wherein the rig control system comprises a rig control workstation usable by personnel to control the well construction equipment, wherein the supervisory controller comprises a processing device and a memory storing a program code, and wherein execution of the program code by the processing device causes the supervisory controller to:
select an operational sequence to be performed by the well construction equipment based on operational status of the well construction equipment and a well construction plan input into the supervisory controller; and
control the well construction equipment, via the rig control system, to cause the well construction equipment to perform the selected operational sequence; and
a supervisory human-machine interface (HMI) communicatively connected with the supervisory controller and usable by the personnel to control the supervisory control system, wherein:
the well construction plan comprises a plurality of planned tasks to be performed by the well construction equipment as part of the well construction operations;
the supervisory control system further comprises a memory device storing a database of operational sequences;
each of the planned tasks is associated with a plurality of the operational sequences stored in the database; and
each operational sequence associated with one of the planned tasks comprises a different plurality of operations to be performed by the well construction equipment to perform the one of the planned tasks.
