The multiphase Sakhalin-1 Project includes the Chayvo field which is located 5 to 7 miles (8 to 11 kilometers) offshore. The Z-11 was drilled to the Chayvo reservoir from the Yastreb rig, the world’s largest land-based drilling rig. Overall, the Chayvo field reached its peak production rate of 250,000 barrels (34,000 metric tons) per day in February 2007 after an on-schedule startup in October 2005. The Z-11 is the 17th ERD producing well to be completed as part of the Sakhalin-1 Project. It was drilled in 61 days, more than 15 days ahead of schedule and below expected cost with no safety or environmental incidents.
