A method and apparatus for sealing a wellbore is described herein. A convertible seal includes a sealing element and a valve. The sealing element is in fluid communication with the valve and fluidly blocks a bore of the convertible seal. The sealing element prevents fluid from flowing through the bore until desired. When desired, the sealing element is removed to allow fluid to flow through the bore. Fluid flow in the bore is controlled by the valve. As a result, the convertible seal has been converted to a flow control seal.
