1. A method, comprising:

  • tracking, automatically by a controller of a drilling rig, a position of a bit at a distal end of a bottom hole assembly coupled to a drill string of the drilling rig during a surge or swab operation through a wellbore environment of a wellbore;

    determining, automatically by the controller at a first time during the surge or swab operation, the wellbore environment comprises a first wellbore environment from the tracked position of the bit based on at least one received drilling parameter relating to the drill string in the wellbore;

    adjusting, dynamically by the controller during the surge or swab operation, a trip speed of the drill string to a first trip speed based on the determined first wellbore environment;

    determining, automatically by the controller at a second time during the surge or swab operation, the wellbore environment comprises a second wellbore environment from the tracked position of the bit based on the at least one received drilling parameter relating to the drill string in the wellbore; and

    adjusting, dynamically by the controller during the surge or swab operation, the trip speed of the drill string to a second trip speed based on the determined second wellbore environment.
