Wellbore Cementing Using a Burst Disc Sub and Reverse Circulation
30 Nov 23
A system for cementing casing using reverse circulation, where the system can include a casing string having multiple casing pipes and a burst disc sub, where the burst disc sub includes a burst disc that is disposed within a cavity formed in the casing string and prevents unwanted flow up the cavity while running casing, where the burst disc, when exposed to a downward force in the cavity exceeding a threshold value, is configured to break apart to allow flow of casing fluid under pressure from the upper portion to the lower portion of the cavity through the burst disc sub, and where the burst disc sub is configured to allow for reverse flow of the casing fluid therethrough when a cement slurry is injected down an annulus formed between the casing string and a formation wall of a wellbore.
