Fill up tool
A fill up tool includes a mandrel; a primary sealing member disposed around the mandrel; and a selectively operable secondary sealing member activated by rotation of the mandrel. In another embodiment, the selectively operable secondary sealing member is activated using hydraulic pressure.
1. A fill up tool, comprising:
a mandrel;
a primary sealing member disposed on the mandrel; and
a selectively operable secondary sealing member activatable by rotation of the mandrel.
2. The tool of claim 1 , further comprising an anti-rotation assembly to inhibit relative rotation of the secondary sealing member with the mandrel.
3. The tool of claim 2 , further comprising an actuator coupled to the anti-rotation assembly and the mandrel.
4. The tool of claim 3 , wherein the rotation of the mandrel causes axial movement of the actuator.
5. The tool of claim 1 , wherein rotation of the mandrel applies a compressive force on the secondary sealing member.
6. The tool of claim 1 , further comprising a load transfer assembly configured to limit transfer of an upward force from the mandrel.
7. The tool of claim 1 , wherein the secondary sealing member is disposed below the primary sealing member.
8. The tool of claim 1 , wherein the secondary sealing member engages an inner surface of the casing.
9. The tool of claim 1 , wherein the mandrel is configured for insertion into a casing, wherein the mandrel is configured to be inserted into the casing by a first amount and by a second amount, wherein the second amount is deeper than the first amount.
10. The tool of claim 9 , wherein the primary sealing member is configured to seal with the casing when the mandrel is inserted into the casing by the first or second amount.
11. The tool of claim 9 , wherein secondary sealing member is activatable by rotation of the mandrel only when the mandrel is inserted into the casing by the second amount.
12. A fill up tool, comprising:
a mandrel;
a primary sealing member disposed on the mandrel;
a selectively operable secondary sealing member disposed on the mandrel; and
a housing for containing the secondary sealing member, wherein the secondary sealing member is axially movable relative to the housing.
13. The fill up tool of claim 12 , wherein the housing is at least partially inserted into a casing.
14. The fill up tool of claim 13 , wherein the housing is adapted to abut the casing.
15. The fill up tool of claim 12 , wherein the secondary sealing member comprises a packer having a recess.
16. A method of running casing, comprising:
providing a fill up tool equipped with a mandrel, a first sealing member, and a second sealing member;
inserting the fill up tool into the casing;
forming a first seal with the casing using the first sealing member;
activating the second sealing member by rotating the mandrel, thereby forming a second seal.
17. The method of claim 16 , wherein rotating the mandrel causes an actuator to apply a compressive force on the second sealing member.
18. The method of claim 16 , further comprising conducting a fill up operation prior to activating the second sealing member.
19. The method of claim 18 , wherein the second sealing member is located outside of the casing.
20. The method of claim 16 , wherein the second sealing member engages an inner surface of the casing.
21. The method of claim 16 , wherein the second sealing member engages an outer surface of the casing.
