Abstract
A well system includes a well platform including a rig floor, a first rig floor robot and a second rig floor robot positioned on the rig floor, wherein the first rig floor robot is configured to guide a lower end of a pipe stand towards a setback position on the rig floor and the second rig floor robot is configured to guide a first pipe joint of the pipe stand into a first mouse hole formed in the rig floor, a mast extending from the rig floor, a racking board coupled to the mast, the racking board configured to secure an upper end of the pipe stand between a pair of finger boards of the racking board, a racking board robot positioned on the racking board and configured to position the upper end of the pipe stand between the pair of finger boards.
Claims18
A well system, comprising:
- a well platform comprising a rig floor;
- a first rig floor robot and a second rig floor robot positioned on the rig floor, wherein the first rig floor robot is configured to guide a lower end of a pipe stand towards a setback position on the rig floor and the second rig floor robot is configured to guide a first pipe joint of the pipe stand laterally across the rig floor and into a first mouse hole formed in the rig floor;
- a mast extending from the rig floor;
- a racking board coupled to the mast, the racking board configured to secure an upper end of the pipe stand between a pair of finger boards of the racking board;
- and
- a racking board robot positioned on the racking board and configured to position the upper end of the pipe stand between the pair of finger boards.
A well system, comprising:
- a well platform comprising a rig floor;
- a first rig floor robot and a second rig floor robot positioned on the rig floor, wherein the first rig floor robot is slidably disposed on a track positioned on the rig floor and configured to guide a lower end of a pipe stand towards a setback position on the rig floor, and the second rig floor robot is configured to guide a first pipe joint of the pipe into a first mouse hole formed in the rig floor;
- a mast extending from the rig floor;
- a racking board coupled to the mast, the racking board configured to secure an upper end of the pipe stand between a pair of finger boards of the racking board;
- and
- a racking board robot positioned on the racking board and configured to position the upper end of the pipe stand between the pair of finger boards.
A well system, comprising:
- a well platform comprising a rig floor;
