Abstract

The invention is a multipurpose system for a drilling and well intervention made of a pivotable, slidable cantilever on a platform adapted to pivot and to slide along an x-y axis; a tower disposed on the cantilever with a mast, a hoist winch, a splittable block connected to the mast, a trolley with a holding member wherein the trolley is moveably mounted to the mast and the splittable block, and a hoist cable that passes over the mast through the splittable block to the trolley; a storage device for storing tubulars; a racking arm secured to the tower for moving tubulars; a reel with coiled tubulars; a moveable injector head for running and retrieving coiled tubulars from the reel; and a retractable trolley moveably mounted on the mast with a holding member and adapted for positioning the tubulars over a well and over an additional work area.

Claims

1. A multipurpose system for a drilling and well intervention comprising:

a. a pivotable, slidable cantilever on a platform adapted to pivot and to slide along an x-y axis;

b. a tower disposed on the cantilever comprising;

i. a mast;

ii. a hoist winch;

iii. a splittable block connected to the mast;

iv. a trolley comprising a holding member wherein the trolley is moveably mounted to the mast and the splittable block;

v. a hoist cable having a first end and a second end wherein the first end is connected to the hoist winch and the hoist cable passes over the mast through the splittable block to the trolley;

c. a storage area with a storage device for storing tubulars;

d. a racking arm secured the pivotable, slidable cantilever and secured with a beam to the tower for moving tubulars;

e. a reel comprising coiled tubulars;

f. a moveable injector head for running and retrieving coiled tubulars from the reel; and

g. a retractable trolley moveably mounted on the mast with a holding member and adapted for positioning the tubulars over a well and over an additional work area.

2. The system of claim 1, wherein a plurality of storage devices are used.

3. The system of claim 1, wherein a plurality of reels are used.

4. The system of claim 1, wherein a plurality of splittable blocks are secured to the mast.

5. The system of claim 1, wherein the storage device is a vertical storage device.

6. The system of claim 1, wherein the racking arm is a horizontal to vertical racking arm.

7. The system of claim 1, wherein the storage area is for the horizontal storing of tubulars.

8. The system of claim 1, wherein the tower is selected from the group consisting of a derrick and a tubular mast.

9. The system of claim 1, wherein the tower further comprises a pair of rails disposed on the tower wherein the rails are parallel to each other and the retractable trolley and the trolley are disposed on the rails.

10. The system of claim 1, further comprising a skiddable frame removably mounted on the cantilever.

11. The system of claim 10, wherein the moveable injector head is mounted on the skiddable frame.

12. The system of claim 10, wherein the skiddable frame and the moveable injector head are movable between the well and a standby position on the cantilever.

13. The system of claim 10, wherein the skiddable frame can be vertically extended and retracted to increase or decrease the vertical distance between the movable injector head and the cantilever.

14. The system of claim 1, wherein the storage device is a racking drum.

15. The system of claim 1, further comprising a crane disposed on the platform.

16. The system of claim 15, further comprising a spare crane.

17. The system of claim 16, wherein the spare crane is mounted on the tower.

18. The system of claim 15, wherein the spare crane is mounted on the racking arm.

19. The system of claim 15, wherein the spare crane is mounted on a racking drum.

20. The system of claim 1, further comprising transportable tubular containers as the storage device.

21. The system of claim 20, further comprising a lifting table disposed on the cantilever for moving the transportable tubular containers to a position vertical to the cantilever.

22. The system of claim 1, further comprising a tubular makeup/breakout device disposed on the cantilever and adapted for making up strings of tubulars.

23. The system of claim 1, further comprising a top drive attached to the retractable trolley.

24. The system of claim 1, further comprising a reel drive mechanism for engaging the reel.

25. The system of claim 1, wherein the platform is a member of the group consisting of a barge, ship, a jack up platform, other floating vessels, and a fixed leg platform.

26. The system of claim 1, wherein the cantilever is mounted on wheels.

27. The system of claim 1, wherein the cantilever pivots on the deck of the platform up to 45 degrees from the position of the tubulars over the well.

28. The system of claim 1, wherein the cantilever has a longitudinal axis and the tower is positioned perpendicular to the longitudinal axis of the contilever.

29. The system of claim 1, wherein the cantilever has a longitudinal axis and the tower is positioned parallel to the longitudinal axis of the cantilever.

30. The system of claim 1, wherein the tower is modular.

31. The system of claim 1, wherein the splittable block comprises a plurality of fixed pulleys and loose pulleys.

32. The system of claim 31, wherein the splittable block comprises at least two loose pulleys.

33. The system of claim 1, further comprising a down whole assembly retrieval winch for engaging a member of the group consisting of the mast, the cantilever, and the platform.

34. The system according to claim 33, wherein the hoist winch and the down hole assembly retrieval winch are each driven by at least one motor with a low inertia.
