Retrievable packer element—anti extrusion barrier

A packer assembly, comprising:

• a tubular body;
• a mandrel circumferentially surrounding the tubular body;
• a gauge ring;
• an anti-extrusion ring, wherein the anti-extrusion ring comprises:
• a first ring comprising a plurality of first ring segments, each first ring segment of the plurality of first ring segments comprising:
• a first ring segment spring channel;
• and
• a retention bolt connector;
• a second ring comprising a plurality of second ring segments, each second ring segment of the second ring segments comprising:
• a second ring segment spring channel;
• and
• a retention bolt expansion channel formed through the second ring;
• and
• a spring disposed in a spring channel, wherein the spring channel comprises the first ring segment spring channel and the second ring segment spring channel;
• and
• a plurality of retention bolts disposed in the retention bolt expansion channel and coupled to the retention bolt connector;
• a force ring;
• and
• a packer element.

A method, comprising:

• deploying a packer system comprising a packer assembly in a casing;
• and
• applying a force to an anti-extrusion ring of the packer assembly using a gauge ring of the packer assembly, the anti-extrusion ring comprising:
• a first ring comprising a plurality of first ring segments;
• a second ring comprising a plurality of second ring segments;
• a spring disposed in a spring channel;
• and
• a retention bolt coupling the first ring and the second ring, comprising:
• a head;
• and
• a connection end distal from the head, wherein the connection end is coupled to a retention bolt connector, wherein applying the force to the anti-extrusion ring expands the anti-extrusion ring and a packer element radially outward and forms a seal against the casing with the packer element.

A method, comprising:

• deploying a packer system comprising a packer assembly in a casing;
• and
• applying a force to an anti-extrusion ring of the packer assembly using a gauge ring of the packer assembly, the anti-extrusion ring comprising:
• a first ring comprising a plurality of first ring segments;
• a second ring comprising a plurality of second ring segments;
• a spring disposed in a spring channel;
• and
• a retention bolt coupling the first ring and the second ring, wherein applying the force to the anti-extrusion ring expands the anti-extrusion ring and a packer element radially outward and forms a seal against the casing with the packer element and wherein when the force is applied to the anti-extrusion ring by the gauge ring, an outer angled surface of a force ring and an inner angled surface of the first ring slide relative to one another such that the first ring expands radially outward and an outer angled surface of the second ring and an inner angled surface of the gauge ring slide relative to one another such that the second ring expands radially outward.
