Abstract

A system of tubulars includes a non-expandable mandrel having a body including an uphole end, a downhole end, and an outer surface. The non-expandable mandrel includes one or more slip members that are outwardly extendable relative to the outer surface. A seal assembly is arranged at the downhole end of the non-expandable mandrel. The seal assembly is settable after outward expansion of the one or more slip members.

First claim

The invention claimed is:

1. A system of tubulars comprising:
a non-expandable mandrel having a body including an uphole end, a downhole end, and an outer surface, the non-expandable mandrel including one or more slip members that are outwardly extendable relative to the outer surface, wherein the non-expandable mandrel includes a first load ring arranged at the uphole end and a second load ring arranged at the downhole end, and a plurality of load bars extending between the first load ring and the second load ring; and
a seal assembly arranged at the downhole end of the non-expandable mandrel, the seal assembly being settable after outward expansion of the one or more slip members.

2. The system of tubulars according to claim 1 , further comprising: a decoupling sleeve coupled to the non-expandable mandrel at the uphole end, the decoupling sleeve including a first plurality of more shear members shearable at a first force.

3. The system of tubulars according to claim 2 , wherein the non-expandable mandrel includes a second plurality of shear members shearable at a second force that is less than the first force.

4. The system of tubulars according to claim 3 , wherein the seal assembly includes a third plurality of shear members shearable at a third force that is substantially equal to the second force.

5. The system of tubulars according to claim 1 , further comprising: a locking ring mounted to the non-expandable mandrel between the first load ring and the second load ring, the locking ring including a plurality of lock ring segments and a plurality of channels that provide passage for respective ones of the plurality of load bars.

6. The system of tubulars according to claim 5 , wherein the locking ring is formed from a plurality of locking ring segments, the plurality of channels being defined by gaps between adjacent ones of the plurality of locking ring segments.

7. The system of tubulars according to claim 1 , wherein each of the one or more slip members includes a tab members that selectively engages at least one of the plurality of load bars, the tab members preventing axial movement of the plurality of load bars prior to deployment of the one or more slip members.

8. The system of tubulars according to claim 7 , wherein each of the plurality of load bars includes at least one tab receiving recess receptive to a corresponding tab members of one of the one or more slip members.

9. A method of setting a downhole seal assembly comprising:
deploying a system of tubulars including a non-expandable mandrel including an uphole portion and a downhole portion, the downhole portion including a seal assembly;
setting one or more slip members carried by the uphole portion of the non-expandable mandrel;
transmitting an axial force through the non-expandable mandrel into the seal assembly after setting the one or more slips by inputting the axial force to one or more load bars carried by the non-expandable mandrel after setting the one or more slip members; and
radially expanding the seal assembly in response to the axial force.

10. The method of claim 9 , wherein setting the one or more slip members includes applying a first axial force to an uphole end of the non-expandable mandrel causing a first plurality of shear members to shear.

11. The method of claim 10 , wherein transmitting the axial force to the non-expandable mandrel includes applying a second axial force, that is greater than the first axial force, to a decoupling sleeve arranged at the uphole end causing a second plurality of shear members to shear.

12. The method of claim 9 , further comprising: restricting axial movement of the one or more load bars relative to the non-expandable mandrel prior to setting the one or more slip members.

13. The method of claim 11 , wherein radially expanding the seal assembly includes applying the second axial force to the seal assembly causing a third plurality of shear members to shear.
