Sequencing for pipe handling

A method for performing operations via a drill rig, the method comprising:

• conducting a drilling operation at a well center;
• conducting a standing operation simultaneously with the drilling operation, wherein the standing operation comprises:
• moving a first tubular single between a feeding table position and a drill floor pickup position via a catwalk;
• moving the first tubular single between the drill floor pickup position and a mousehole stickup position via a tubular delivery arm and a lower stabilizing arm;
• holding the first tubular single in the mousehole stickup position via at least one stand constraint;
• moving a second tubular single between the feeding table position and the drill floor pickup position via the catwalk;
• moving the second tubular single between the drill floor pickup position and a mousehole make/brake position via the tubular delivery arm and the lower stabilizing arm;
• operating a roughneck on a joint between the first and second tubular singles;
• moving a tubular stand comprising the first and second tubular singles between a mousehole position and a stand handoff position;
• and
• moving the tubular stand between a stand handoff position and a setback position via a transfer bridge racker and a setback guide arm.

A method for performing operations via a drill rig, the method comprising:

• moving a tubular string relative to the wellbore via a top drive;
• moving a tubular single between a feeding table position and a drill floor pickup position via a catwalk;
• moving the tubular single between the drill floor pickup position and a well center position via a top drive and a lower stabilizing arm;
• and
• operating a roughneck on a joint between the tubular single and the tubular string in the wellbore.

A method for performing operations via a drill rig, the method comprising:

• moving a casing string relative to the wellbore via a top drive;
• moving a casing single between a feeding table position and a drill floor pickup position via a catwalk;
• moving the tubular single between the drill floor pickup position and a well center position;
• operating a casing running tool between the casing single and the top drive;
• and
• operating the top drive on a joint between the casing single and the casing string in the wellbore.

A method for performing operations via a drill rig, the method comprising:

• drilling a wellbore by rotating a drill string via a top drive;
• setting slips at the drill rig floor so that the drill string is at a stickup height relative to the drill rig floor;
• breaking out the connection between the top drive and the drill string;
• moving a drill string stand from a setback position to a stand handoff position;
• moving a drill string stand from a stand handoff position to a well center position;
• making up a joint between the drill string stand and the drill string;
• making up a connection between the drill string stand and the top drive;
• opening the slips at the drill rig floor;
• and
• continuing drilling a wellbore by rotating the drill string via the top drive.
