Method and system for positioning a drilling or other large structure using attached positioning shoes with individually addressable wireless vertical and rotational control

A drilling rig mobility method for moving a drilling rig in an oilfield, comprising:

• attaching a plurality of independently controllable positioning shoes to the drilling rig and through separate and coordinated position control commands to each of said plurality of independently controllable positioning shoes repositioning the drilling rig, said attaching step further comprising, for each of said independently controllable positioning shoes, the steps of:
• containing a hydraulic actuator and wireless control using a housing attached to the drilling rig and providing structural enclosure for containing a hydraulic actuator and wireless control circuitry,
• providing vertical and horizontal force in response to wireless control signals from said wireless control circuitry using said hydraulic actuator for;
• communicating wireless position and control data and instructions with a remote wireless communications device using said wireless control circuitry for and converting said wireless position and control data and instructions to hydraulic actuator control signals;
• vertically elevating said hydraulic actuator using a positioning shoe cylinder stomper for receiving and transferring said vertical and rotational force from said hydraulic actuator;
• rigidly connecting a positioning shoe foot assembly to said positioning shoe cylinder stomper, and receiving and transferring said horizontal force from said hydraulic actuator;
• slidably connecting a positioning shoe traverse cylinder with said positioning shoe foot assembly and receiving and horizontally moving a hydraulic piston and rail assembly in response to said horizontal movement force, said positioning shoe traverse cylinder for contacting the oilfield ground moving said drilling rig;
• and further associating said positioning shoe cylinder stomper, said positioning shoe traverse cylinder, and said positioning shoe traverse cylinder for providing continuously variable position control of said independently controllable positioning shoe.

A drilling rig for use in an oilfield or energy production field and capable of being repositioned in the field using a plurality of wireless command and control signals, said drilling rig comprising:

• a superstructure for supporting drilling equipment and directing said drilling equipment into a wellbore;
• a base for supporting said superstructure and providing further structural foundation to the drilling rig;
• an operator shack for providing an operating space for drilling operators to occupy during drilling operations;
• a plurality of base support structures for supporting said base and further providing structure on which to attach a drilling rig mobility system for moving a drilling rig in an oilfield, said drilling rig mobility system comprising:
• a plurality of independently controllable positioning shoes for attaching to the drilling rig and through separate and coordinated position control commands to each of said plurality of independently controllable positioning shoes repositioning the drilling rig, each of said independently controllable positioning shoes further comprising:
• a housing attached to the drilling rig and providing structural enclosure for containing a hydraulic actuator and wireless control circuitry,
• said hydraulic actuator for providing vertical and horizontal force in response to wireless control signals from said wireless control circuitry;
• said wireless control circuitry for communicating wireless position and control data and instructions with a remote wireless communications device and converting said wireless position and control data and instructions to hydraulic actuator control signals;
• a positioning shoe cylinder stomper for vertically elevating said hydraulic actuator and for receiving and transferring said vertical and rotational force from said hydraulic actuator;
• a positioning shoe foot assembly rigidly connected to said positioning shoe cylinder stomper and associated to receive and transfer said horizontal force from said hydraulic actuator;
• a positioning shoe traverse cylinder slidably connected with said positioning shoe foot assembly and comprising a hydraulic piston and rail assembly for receiving and horizontally moving in response to said horizontal movement force, said positioning shoe traverse cylinder for contacting the oilfield ground moving said drilling rig;
• and further wherein said positioning shoe cylinder stomper, said positioning shoe traverse cylinder, and said positioning shoe traverse cylinder associate for continuously variable position control of said independently controllable positioning shoe.
