摘要
This specification discloses a method and system for cementing a casing string with returns to the seafloor in an offshore wellbore. The hydrostatic pressure at a preselected point within the annulus formed intermediate the casing string and the wellbore wall is monitored during a cementing operation to determine when cement returns in the annulus reach the seafloor and thereafter the cementing operation is terminated.
