Abstract
A ball seat is provided in a subterranean string for a preferably non-metallic ball. At least one barb is downwardly oriented toward the ball seat and disposed uphole such that as the ball passes the barb, a groove is worn or cut into the outer surface of the ball. When the ball is seated and motion of the ball stops, the end of the barb is at groove bottom of the ball. In that manner, the barb bears against the ball to keep the ball on the seat to prevent fluids from going further downhole as treatment takes place above the ball. The barb can have a variety of shapes that force the ball to be extruded over it to score the outer surface of the ball and keep the ball against the seat. Ultimately, the ball can be blown through the seat with enough pressure applied above it.
