## Abstract

A packer system includes a gauge ring, an expanding ring arranged adjacent to the gauge ring, a back-up ring, a packer element arranged adjacent to the back-up ring, and a support ring arranged between the back-up ring and the expanding ring. The support ring promotes radial outward expansion of the expanding ring.

## Claims

### Claim 1

A packer system comprising:
a tubular having a surface;
a gauge ring provided on the tubular;
an expanding ring arranged adjacent to the gauge ring, the expanding ring including a first angled surface abutting the gauge ring and a second, opposing angled surface having a first angled portion that extends at a first angle relative to the surface and a second angled portion that extends at a second angle relative to the surface, the first angle being non-perpendicular relative to the surface;
a back-up ring including a first surface section and a second surface section, the first surface section extending at a non-perpendicular angle relative to the surface;
a packer element arranged adjacent to the back-up ring, the first surface section and the second surface section encapsulating a portion of the packer element; and
a support ring arranged axially between the back-up ring and the expanding ring, the support ring including a first angled surface portion that is complimentary to the first angle and a second angled surface portion that is complimentary to the first angled surface section, the support ring promoting radial outward expansion of the expanding ring.

### Claim 2 (depends on 1)

The packer system according to claim 1, wherein the first angle is distinct from the second angle.

### Claim 3 (depends on 1)

The packer system according to claim 1, wherein the first angled surface portion nests against the second angled surface.

### Claim 4

A resource exploration and recovery system comprising:
a surface system; and
a downhole system including a string of tubulars, at least one of the string of tubulars including a surface supporting a packer system comprising:
a gauge ring provided on the string of tubulars;
an expanding ring arranged adjacent to the gauge ring, the expanding ring including a first angled surface abutting the gauge ring and a second, opposing angled surface having a first angled portion that extends at a first angle relative to the surface and a second angled portion that extends at a second angle relative to the surface, the first angle being non-perpendicular relative to the surface;
a back-up ring including a first surface section and a second surface section, the first surface section extending at a non-perpendicular angle relative to the surface;
a packer element arranged adjacent to the back-up ring, the first surface section and the second surface section encapsulating a portion of the packer element; and
a support ring arranged axially between the back-up ring and the expanding ring, the support ring including a first angled surface portion that is complimentary to the first angle and a second angled surface portion that is complimentary to the first angled surface section, the support ring promoting radial outward expansion of the expanding ring.

### Claim 5 (depends on 4)

The resource exploration and recovery system according to claim 4, wherein the first angle is distinct from the second angle.

### Claim 6 (depends on 4)

The resource exploration and recovery system according to claim 4, wherein the first angled surface portion nests against the second angled surface.
