  • Patent number: 11321788
    Abstract: Systems and methods for optimizing oilfield rig fleet scheduling and deployment are disclosed. Wells are identified to have time constraints by which they are grouped into “ON”, “BY”, and “ADD” categories. ON wells have a beginning drilling availability window; BY wells have an ending drilling availability time only; and ADD wells have no beginning or ending time of drilling availability. The systems and methods optimize scheduling with ON wells having higher priority than BY wells, and BY wells having higher priority than ADD wells.

  • Patent number: 11306549
    Abstract: Embodiments of a vertical pipe handler system (50) and method of its use include a casing tong handling tool (10) connected to a lifting tool (55) having a gripper head (51) and supported by an arm (53) of the vertical pipe handler system. The casing tong connection (33) of the handling tool is located toward the tool's lower end (21) and may be offset in a horizontal direction from the connection (29) to the lifting tool. The casing tong (60) then hangs off-center relative to the lifting tool. The amount of offset may be effective to prevent interference between the gripper head and a tubular being handled by the casing tong.
