Abstract
A technique facilitates deployment and operation of actuatable plugs, e.g. frac plugs or bridge plugs. According to one embodiment, the plug comprises a flexible element slidably mounted on a portion of a cone, e.g. an upper cone. The upper cone comprises a tapered surface which works in cooperation with upper slips movably secured to the upper cone. The bridge plug also comprises a lower cone which comprises a lower tapered surface which works in cooperation with lower slips movably secured to the lower cone. Depending on the application, the plug may be constructed with each of these features combined into an overall assembly or with a portion of these features to facilitate plug operation in a specific environment and operation.
