Managed Pressure Cementing
for Top-Hole Sections

Reduce the Annulus Pressure When Cementing and Apply Pressure While the Cement is Setting

By creating a closed-loop circulation system the annulus pressure can be adjusted when displacing the cement to get Top of Cement to Seabed.

Controlling the Annulus Pressure When Cementing

By reducing the pressure on the conductor housing the pressure during the cement placement is kept below the fracture pressure.

Adding Pressure During Curing Process of the Cement

By using valves on the low-pressure wellhead, the annular pressure can be managed while setting to provide integrity by fully isolating the formation.
