Project Profile
Value: US$14 billion
Location: 350 km offshore the province of Newfoundland and Labrador
Start-up Month: Q4
Start-up Year: 2017
Upstream Oil Reserves: 731 million bbl
Capacity: 150,000 bpd (peak)
Water Depth: 100 m
Upstream Gas Reserves: 400 billion ft³
The Hebron field (Hebron, Ben Nevis and West Ben Nevis fields) is located 350 km offshore the province of Newfoundland and Labrador. Oil field with recoverable reserves estimated at 700 million barrels. Production is expected to be around 150,000-170,000 bpd. Hebron is challenging due to Heavy Oil and complex reservoirs. The Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB) estimates that the development contains 570 million barrels of recoverable oil. First oil is due between 2016 and 2018. The initial development will focus on the Hebron and West Ben Nevis. The Ben Nevis field will be a possible future satellite tie-back. Oil will be produced and shipped by shuttle tanker through the existing distribution system used at the Hibernia field. The oil is of 20 degree API which presents production challenges as the viscosity can be 10 to 20 times higher than that of water.
The GBS (gravity-based structure) will have the capacity to store up to 1.45 million barrels of oil (180,000-230,000 cubic metres). At peak, Hebron will pump 150,000 barrels per day, while the topsides will need a liquids handling capacity of up to 315,000 bpd due to the high volumes of produced water. It will also have to inject between 100 million and 175 million cubic feet per day of gas. The topsides will weigh 20,000-28,000 tons. The platform will need to support up to 55 well slots.The platform will have a production capacity of 120,000 bpd to 175,000 bpd, provide living quarter for 140 to 200 personnel, a single onboard drilling rig, as well as handling systems for produced water and gas.
