21. A method of selectively sealing a portion of a wellbore, comprising the steps of:
a) providing a rupture disc system comprising: a housing including a housing central bore; a rupture disc disposed within the housing central bore, wherein the rupture disc includes a base extending from a distal surface to a proximal end and a central portion extending across the proximal end of the base, wherein the central portion traverses a central axis defined by the base and extends across the housing central bore, wherein at least one surface of the central portion includes a plurality of facets defined by a plurality of seams, wherein at least one of the plurality of facets is a flat surface having an angular orientation that varies from the angular orientation of adjacent facets; and one or more sealing members engaging the rupture disc and an inner surface of the housing central bore to fluidly seal the housing central bore;
b) positioning the rupture disc system within a wellbore to fluidly seal a portion of the wellbore with the rupture disc disposed in the housing central bore; and
c) generating a rupture event to fracture the rupture disc, thereby opening the housing central bore and allowing fluid flow to the portion of the wellbore.
