A downhole apparatus comprises a casing string with a frangible disk positioned therein. A flow barrier is connected in the casing string and spaced downwardly from the frangible disk. The frangible disk and the flow barrier define a buoyancy chamber. The sliding sleeve will impact and shatter the frangible disk into a plurality of pieces that will pass downwardly in the casing after the casing has been lowered to a desired depth.
