description A drillable bridge plug includes a mandrel having external splines disposed on an outer surface of the mandrel, a sealing element disposed around the mandrel, an upper cone disposed around the mandrel proximate an upper end of the sealing element, and a lower cone disposed around the mandrel proximate the lower end of the sealing element, wherein an inner surface of the lower cone comprises internal splines configured to engage the external splines. The drillable bridge plug also includes an upper and a lower slip assembly disposed around the mandrel, and an upper and lower ring assembly each including a first segmented barrier ring, a second segmented barrier ring, and a back-up ring disposed proximate sealing element. A method of setting the drillable bridge plug and a method of removing the drillable bridge plug are disclosed.
