Abstract

Wellbore tubulars including selective stimulation ports (SSPs) sealed with sealing devices and methods of operating the same are disclosed herein. The wellbore tubulars include a tubular body that defines a tubular conduit and a plurality of selective stimulation ports. Each selective stimulation port includes an SSP conduit and a sealing device seat. The wellbore tubulars further include a plurality of sealing devices. Each sealing device includes a primary sealing portion that is seated on a corresponding sealing device seat and forms a primary seal with the corresponding sealing device seat. Each sealing device also includes a secondary sealing portion that extends from the primary sealing portion and forms a secondary seal between the primary sealing portion and the corresponding sealing device seat. The methods include methods of stimulating a subterranean formation utilizing the wellbore tubulars.
