Publication number: 20220235623Abstract: A plug assembly for opening a subterranean wellbore comprises a tubular housing and a first frangible element comprising an activation component. The first frangible element has a first orifice in an uphole side that extends at least partially through the first frangible element. The activation component initially seals the first orifice to prevent fluid communication from the uphole side of the first frangible element with the first orifice. After the activation component is activated, fluid communication is enabled from the uphole side of the first frangible element with the first orifice.Type: ApplicationFiled: January 25, 2022Publication date: July 28, 2022Inventors: Viggo Brandsdal, Geir Valestrand Aasheim
