Conference ·
OSTI ID:5375156
The Shell/Esso Central Cormorant Development is now over halfway through its drilling and completing phase. Drilling techniques required for such a development differ substantially from normal drilling practices. These differences are reviewed and the constraints and procedures required to ensure safe and parallel drilling/completion operations in conjunction with UMC production are explained. Other areas of experience that are discussed are the weather influence on operations, rig anchoring and underwater surveillance.
