Abstract
A high expansion bridge plug comprising an elastomer element assembly and a control assembly for generating a compressive force against the elastomer element assembly. The elastomer element assembly comprises a first element stack and a second element stack with the first element stack comprising a first grouping of male and female elements and the second element stack comprising a second grouping of male and female elements. The compressive force generated causes the male element and the female element to expand and the female element to at least partially swallow the male element. The male and female elements can be conical shape, and an angle of a conical element can be between 5-25 degrees, and the length of the top female element is greater than the length of the middle or bottom male element.
