Cementing technique deployed for Total in the North Sea
This work scope was the first 20-in. surface casing SeaCure job completed in the North Sea.
The system was deployed from the Diamond Offshore semisubmersible Ocean Valiant in a water depth of 115 m (377 ft).
SeaCure provides stabbed-in, inner string cementing for subsea wells.
According to DeltaTek, benefits include no need for shoe tracks and therefore clean out runs, improved cement placement and reduced displacement, offline casing pressure testing, improved drill out performance and minimized risk of damage to the bottomhole assembly.
Chief Commercial and Operations Officer Dave Shand said: “... A key deliverable was to get cement back to the seabed - SeaCure facilitates improved cement placement and this was the first-time cement has successfully been brought back to the seabed in this part of the North Sea.”
