Abstract

A self-erecting launcher assembly includes a mobile unit, and a magazine positioned in a receptacle of the mobile unit. The magazine includes a plurality of drones. A rail unit is secured to the mobile unit and moves between a closed position and an elevated position. A platform may be secured to the rail unit and is movable in an upward direction and a downward direction along a length of the rail unit. The platform is movable when the rail unit is in its elevated position. The magazine or the plurality of drones may be positioned on the platform, such that the platform moves the magazine or the plurality of drones from the mobile unit to at least one wellhead. A manipulator arm is secured to the platform and selects a drone of the plurality of drones and delivers the selected drone into a lubricator positioned at the wellhead.

First claim

The invention claimed is:

1. A self-erecting launcher assembly comprising:
a mobile unit comprising a receptacle;
a magazine including a plurality of drones positioned in the receptacle;
a rail unit secured to the mobile unit, the rail unit movable between a closed position and an elevated position; and
a platform configured to move the magazine or the plurality of drones from the mobile unit to at least one wellhead.

2. The self-erecting launcher assembly of claim 1 , wherein the mobile unit further comprises a magazine loading bay in communication with the receptacle.

3. The self-erecting launcher assembly of claim 1 , wherein the mobile unit further comprises:
a conveyor system in the receptacle; and
a magazine retrieval zone in communication with the receptacle,
wherein the conveyor system is configured to move the magazine from a magazine loading bay to the magazine retrieval zone.

4. The self-erecting launcher assembly of claim 3 , wherein the magazine is configured to move within the receptacle to the magazine retrieval zone via the conveyor system.

5. The self-erecting launcher assembly of claim 1 , further comprising:
a ballistic limiter configured to prevent or limit ballistic transfer from a first drone to a second drone positioned in the magazine in the event of detonation of an explosive component of the first drone.

6. The self-erecting launcher assembly of claim 1 , wherein the rail unit further comprises:
a pair of spaced apart side rails, wherein
a first rail of the pair of spaced apart side rails includes a first end pivotably connected to the mobile unit, and a second end spaced apart from the first end, and
a second rail of the pair of spaced apart side rails includes a first end pivotably connected to the mobile unit, and a second end spaced apart from the first end.

7. The self-erecting launcher assembly of claim 6 , further comprising:
a pair of telescoping arms, wherein
a first telescoping arm of the pair of telescoping arms is configured to move a first rail of the pair of spaced apart side rails, and
a second telescoping arm of the pair of telescoping arms is configured to move a second rail of the pair of spaced apart side rails.

8. The self-erecting launcher assembly of claim 7 , wherein
the first telescoping arm is connected to the first rail at a position between the first end and the second end of the first rail, and
the second telescoping arm is connected to the second rail at a position between the first end and the second end of the second rail.

9. The self-erecting launcher assembly of claim 1 , further comprising:
a manipulator arm secured to the platform,
wherein the manipulator arm is configured to select a drone of the plurality of drones and delivers the selected drone into a lubricator.

10. The self-erecting launcher assembly of claim 9 , further comprising:
a control unit configured to communicate with at least one of the mobile unit, the magazine, the plurality of drones, the rail unit, the platform, the manipulator arm, and an electrical motor.

11. A wellbore deployment system comprising:
a plurality of self-erecting launcher assemblies, each self-erecting launcher assembly of the plurality of self-erecting launcher assemblies comprising:
a mobile unit comprising a receptacle;
a magazine including a plurality of drones positioned in the receptacle;
a rail unit secured to the mobile unit, the rail unit movable between a closed position and an elevated position;
a platform configured to move the magazine or the plurality of drones from the mobile unit to at least one wellhead; and
a control unit configured to manage functionality and operation of the plurality of self-erecting launcher assemblies.

12. The wellbore deployment system of claim 11 , wherein the mobile unit comprises:
at least one side wall having an upper portion and a lower portion;
a roof connected to the upper portion of the at least one side wall; and
a floor connected to the lower portion of the at least one side wall,
wherein the receptacle is bounded by the at least one side wall, the roof and the floor.

13. The wellbore deployment system of claim 12 , wherein the mobile unit further comprises a magazine loading bay in communication with the receptacle.

14. The wellbore deployment system of claim 13 , wherein the magazine loading bay is positioned in the at least one side wall.

15. The wellbore deployment system of any one of claim 11 , wherein the rail unit further comprises:
a pair of spaced apart side rails, wherein
a first rail of the pair of spaced apart side rails includes a first end pivotably connected to the mobile unit, and a second end spaced apart from the first end, and
a second rail of the pair of spaced apart side rails includes a first end pivotably connected to the mobile unit, and a second end spaced apart from the first end.

16. A wellbore deployment system comprising:
a self-erecting launcher assembly comprising:
a mobile unit comprising a receptacle;
a magazine positioned in the receptacle, the magazine including a plurality of drones;
a rail unit secured to the mobile unit, the rail unit movable between a closed position and an elevated position; and
a platform configured to move the magazine or the plurality of drones from the mobile unit to at least one wellhead; and

a location adjuster configured to move the self-erecting launcher assembly from a first wellhead to additional wellheads.

17. The wellbore deployment system of claim 16 , wherein the location adjuster comprises at least one of:
a plurality of wheels secured to the mobile unit; and
a track rail.

18. The wellbore deployment system of claim 16 , wherein the location adjuster comprises:
a rotational unit, wherein
the mobile unit is positioned on the rotational unit, and
the mobile unit is movable between a first wellhead and additional wellheads.

19. The wellbore deployment system of claim 16 , wherein the location adjuster comprises:
a scissor lift configured to move the mobile unit in an upward direction to the height of the wellhead.

20. The wellbore deployment system of claim 16 , wherein the rail unit further comprises:
a pair of spaced apart side rails, wherein
a first rail of the pair of spaced apart side rails includes a first end pivotably connected to the mobile unit, and a second end spaced apart from the first end, and
