Shear thickening fluid controlled tool

1. A tool for use in a wellbore, comprising:

a seal assembly;

a frustoconical member configured to force the seal assembly radially outward into engagement with the wellbore; and

a shear thickening fluid disposed within a volume bounded by the seal assembly and the frustoconical member such that the shear thickening fluid directly contacts the seal assembly and the frustoconical member.

2. The tool of claim 1 , wherein the seal assembly comprises a seal carrier, a first seal, and a second seal, and wherein the shear thickening fluid is contained within the volume by the first and second seals.

3. The tool of claim 2 , wherein the first and second seals are flexible seal members configured to contain the shear thickening fluid within the volume while allowing for contraction and expansion of the shear thickening fluid.

4. The tool of claim 3 , wherein the seal carrier comprises one or more ports for supplying the shear thickening fluid into the volume.

5. The tool of claim 1 , wherein the shear thickening fluid comprises silicon suspended in glycol.

6. The tool of claim 1 , wherein the frustoconical member is movable relative to the seal assembly when the shear thickening fluid is in a substantially fluid state.

7. The tool of claim 1 , wherein the frustoconical member is prevented from moving relative to the seal assembly when the shear thickening fluid is in a substantially solid state.

8. The tool of claim 1 , wherein the volume is reduced as the frustoconical member is moved underneath the seal assembly, thereby compressing the shear thickening fluid.

9. The tool of claim 1 , wherein the shear thickening fluid is compressed when the frustoconical member is moved relative to the seal assembly.

10. A method of controlling a tool in a wellbore, comprising:

transmitting a force from a frustoconical member to a seal assembly, wherein a shear thickening fluid is disposed within a volume bounded by the frustoconical member and the seal assembly such that the shear thickening fluid directly contacts the frustoconical member and the seal assembly;

changing the shear thickening fluid from a substantially fluid state to a substantially solid state; and

preventing relative movement between the frustoconical member and the seal assembly by changing the shear thickening fluid from the substantially fluid state to the substantially solid state.

11. The method of claim 10 , wherein the shear thickening fluid is changed from the substantially fluid state to the substantially solid state by applying a compression force to the shear thickening fluid.

12. The method of claim 10 , further comprising containing the shear thickening fluid in the volume by a first seal and a second seal of the seal assembly.

13. The method of claim 10 , further comprising supplying the shear thickening fluid into the volume through one or more ports of a seal carrier of the seal assembly.

14. The method of claim 10 , wherein the shear thickening fluid comprises silicon suspended in glycol.

15. The method of claim 10 , further comprising moving the frustoconical member relative to the seal assembly when the shear thickening fluid is in the substantially fluid state.

16. The method of claim 10 , wherein the volume is reduced as the frustoconical member is moved underneath the seal assembly, thereby compressing the shear thickening fluid.

17. The method of claim 10 , further comprising transmitting the force from the seal assembly to shear a releasable member and force a slip assembly radially outward into engagement with the wellbore.

18. The method of claim 17 , further comprising subsequently forcing the frustoconical member underneath the seal assembly to force the seal assembly radially outward into engagement with the wellbore.

19. The method of claim 10 , wherein the force comprises a mechanical, hydraulic, pneumatic, or electrical force.
