Abstract:
A bridge plug for use in a wellbore having an anchoring system to grip the inner surface of the surrounding wellbore, as well as a sealing system or packing element to seal against the inner surface. A hinged flapper permits flow of fluid in one axial direction through a central through bore, but can selectively contact against a seat to create a fluid pressure seal and prevent fluid flow through said central through bore in an opposite axial direction. The flapper can be manufactured of frangible material and/or dissolvable material, permitting selective removal of the flapper when desired.

Claim (Index 1):
A valve assembly comprising:\n a) a body section having an upper surface, outer surface, and a central flow bore defining a first diameter, and having an upper opening defining a seat at said upper surface; b) at least one slip member disposed on said outer surface adapted to selectively grip against an inner surface of a wellbore; c) at least one elastomeric sealing member disposed on said outer surface adapted to selectively form a fluid pressure seal against said inner surface of said wellbore; d) a flapper hingedly attached to said body section, wherein said flapper can move between a substantially open configuration, and a substantially closed configuration wherein said flapper contacts said seat and said transverse support member; and e) a spring configured to bias said flapper off of said seat until fluid pressure acting on said flapper overcomes force exerted by said spring.
