Abstract:
A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.

Claim (Index 1):
A float tool configured for use in a casing string for a wellbore containing a well fluid and having an upper, substantially vertical portion, a lower, substantially horizontal portion, and a bend portion connecting the upper and lower portions, the float tool comprising:\n a rupture disc having a rupture burst pressure that is greater than a fluid pressure imposed on the rupture disc by a fluid above the rupture disc sufficient to run the casing string into the lower, substantially horizontal portion of the wellbore.
