Abstract

A wellbore servicing tool is disclosed, which includes a packer element that exhibits radial expansion upon being longitudinally compressed, wherein the packer element is movably positioned about a mandrel generally downward relative to an upper housing, wherein the wellbore servicing tool is selectively transitionable from an unset configuration to a set configuration or from the unset configuration to the set configuration upon rotation of the upper housing with respect to the mandrel.

First claim

What is claimed is:

1. A wellbore servicing tool comprising:
a mandrel generally defining an axial flowbore and an outer cylindrical surface, at least a portion of the outer cylindrical surface comprising a threaded exterior surface;
an upper housing comprising a first inner cylindrical surface, that comprises a threaded interior surface and a housing-tool interface that is structured and arranged to engage a housing-engagement member of a setting tool and, wherein the upper housing is movably positioned about at least a portion of the mandrel such that the threaded exterior surface at least partially engages the threaded interior surface;
a packer element exhibiting radial expansion upon being longitudinally compressed, wherein the packer element is movably positioned about at least a portion of the mandrel generally downward relative to the upper housing; and
a lower housing generally defining a second inner cylindrical surface, wherein the lower housing is movably positioned about at least a portion of the mandrel,
wherein the wellbore servicing tool is selectively transitionable from an unset configuration to a set configuration upon a decrease in longitudinal distance between the upper housing and the lower housing along the mandrel,
wherein the wellbore servicing tool is selectively transitionable from the set configuration to the unset configuration upon an increase in longitudinal distance between the upper housing and the lower housing, and
wherein the rotation of the upper housing with respect to the mandrel in a setting direction decreases the longitudinal distance between the upper housing and the lower housing along the mandrel; and wherein the packer element is radially expanded in the set configuration.

2. The wellbore servicing tool of claim 1 , further comprising a plurality of slip segments disposed about at least a portion of the mandrel generally upward from the lower housing, wherein the plurality of slip segments are configurable between a radially retracted position and a radially expanded position.

3. The wellbore servicing tool of claim 2 , wherein the plurality of slip segments are disposed about the portion of the mandrel generally downward from the packer element.

4. The wellbore servicing tool of claim 2 , further comprising a slip retainer.

5. The wellbore servicing tool of claim 1 , wherein the wellbore servicing tool is configured to be selectively coupled to the setting tool.

6. The wellbore servicing tool of claim 5 , wherein the mandrel comprises a mandrel-tool interface, wherein the mandrel-tool interface engages a mandrel-engagement member of the setting tool.

7. The wellbore servicing tool of claim 6 ,
wherein the mandrel-tool interface comprises a groove, a slot, a notch, or combinations thereof, and
wherein the mandrel-engagement member comprises a radially outward biased torque key, lug, pin, extendable member, or combinations thereof.

8. The wellbore servicing tool of claim 1 ,
wherein the housing-tool interface comprises a groove, a slot, a notch, or combinations thereof, and
wherein the housing-engagement member comprises a radially outward biased torque key, lug, pin, extendable member, or combinations thereof.

9. The wellbore servicing tool of claim 1 , wherein the upper housing comprises a first one or more ports, wherein the lower housing comprises a second one or more ports, wherein the first one or more ports and the second one or more ports provide a route of fluid communication between the axial flowbore and an exterior of the wellbore servicing tool when the wellbore servicing tool is in the unset configuration and wherein the first one or more ports and the second one or more ports does not provide the route of fluid communication between the axial flowbore and an exterior of the wellbore servicing tool when the wellbore servicing tool is in the set configuration.

10. A wellbore servicing system comprising:
a setting tool disposed within a wellbore; and
a wellbore isolation tool selectively coupled to the setting tool and comprising:
a mandrel generally defining an axial flowbore and an outer cylindrical surface, at least a portion of the outer cylindrical surface comprising a threaded exterior surface;
an upper housing comprising a first inner cylindrical surface, that comprises a threaded interior surface and a housing-tool interface that is structured and arranged to engage a housing-engagement member of a setting tool and, wherein the upper housing is movably positioned about at least a portion of the mandrel such that the threaded exterior surface at least partially engages the threaded interior surface;
a packer element exhibiting radial expansion upon being longitudinally compressed, wherein the packer element is movably positioned about at least a portion of the mandrel generally downward relative to the upper housing; and
a lower housing generally defining a second inner cylindrical surface, wherein the lower housing is movably positioned about at least a portion of the mandrel,
wherein the wellbore isolation tool is selectively transitionable from an unset configuration to a set configuration upon a decrease in longitudinal distance between the upper housing and the lower housing along the mandrel,
wherein the wellbore isolation tool is selectively transitionable from the set configuration to the unset configuration upon an increase in longitudinal distance between the upper housing and the lower housing, and
wherein the rotation of the upper housing with respect to the mandrel in a setting direction decreases the longitudinal distance between the upper housing and the lower housing along the mandrel.

11. The wellbore servicing system of claim 10 , wherein the wellbore is cased.

12. The wellbore servicing tool of claim 10 ,
wherein the housing-tool interface comprises a groove, a slot, a notch, or combinations thereof, and
wherein the housing-engagement member comprises a radially outward biased torque key, lug, pin, extendable member, or combinations thereof.

13. The wellbore servicing tool of claim 10 , wherein the mandrel comprises a mandrel-tool interface, wherein the setting tool comprises a mandrel-engagement member, and wherein the mandrel-tool interface engages the mandrel-engagement member.

14. The wellbore servicing tool of claim 13 ,
wherein the mandrel-tool interface comprises a groove, a slot, a notch, or combinations thereof, and
wherein the mandrel-engagement member comprises a radially outward biased torque key, lug, pin, extendable member, or combinations thereof.

15. A wellbore servicing method comprising:
positioning a wellbore isolation tool within a wellbore, wherein the wellbore isolation tool is positioned within the wellbore selectively coupled to a setting tool;
engaging a housing-tool interface disposed on an inner cylindrical surface of an upper tool housing of the wellbore isolation tool with a housing-engagement member of the setting tool; and
setting the wellbore isolation tool comprising rotating the upper housing of the wellbore isolation tool about an exterior of a mandrel of the wellbore isolation tool in a setting direction, wherein rotating the upper housing in the setting direction radially expands a packer element.

16. The wellbore servicing method of claim 15 , further comprising uncoupling the setting tool from the wellbore isolation tool and removing the setting tool from the wellbore.

17. The wellbore servicing method of claim 16 , further comprising applying a fluid pressure to a first portion of the wellbore, wherein the wellbore isolation t
