Reliable deepwater zonal isolation

In deep water, cementing operations are performed in technically and logistically challenging environments because of the risks associated with the conductor and surface casing cementing. Understanding these technical challenges is key to designing cement slurries that can meet deepwater specifications and provide required zonal isolation.
