Ferrand-1
Year: 2018
Region: : Carnarvon Basin, Western Australia
Water depth: 1,500 m
Final inclination: 0.12 degrees
CAN-ductor (pre-installed)
Partnering with Woodside Energy, ICON Engineering and Siem Offshore Australia the installation of a CAN-ductor, at Woodside Energy’s Ferrand-1 exploration well was, at 1500m, the deepest CAN-ductor used to date. It was also the first installation in the Southern hemisphere and the first to be deployed and recovered from an anchor-handling vessel (AHTS).
Using a CAN-ductor to facilitate the drilling of a subsea exploration well, located in Block WA-404-P, approximately 260 km north-west of Dampier, Western Australia proved a critical piece towards Woodside Energy’s “Punch and Go” concept. Already known, the use of the CAN-ductor leads to significant costs savings with three to four rig days, including plugging and abandonment (P&A) operations, saved from the drilling schedule. In addition, higher operational and accidental well load capacities, fatigue risk mitigation and a reduced environmental footprint.
This project was a real team effort and we must acknowledge and thank Woodside Energy, ICON Engineering and Siem Offshore Australia for their collaboration.
