Patent number: 11697968Abstract: 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.Type: GrantFiled: February 28, 2022Date of Patent: July 11, 2023Assignee: NCS MULTISTAGE INC.Inventors: Donald Getzlaf, Marty Stromquist, John Ravensbergen, David Devlin, Douglas Braden, Travis Harris
