Shell Alaska, which on Sunday began drilling operations in Chukchi Sea, off Alaska, has decided to temporarily move off the Burger-A well to avoid potentially encroaching sea ice.
Once the ice moves on, the Noble Discoverer drillship will re-connect to anchors and continue drilling. Shell uses a combination of satellite images, radar and on-site reconnaissance to monitor ice movement.
