The Sable Offshore Energy Project is divided into two 'tiers' of offshore development. The first tier was completed in December 1999 and involved the development of the Thebaud, North Triumph, and Venture fields, as well as the construction of three offshore platforms, an onshore gas plant and an onshore fractionation plant. Gas production commenced on December 31, 1999. Alma, the first Tier II platform came onstream in late 2003 while production from South Venture, the second field began late in 2004. In 2006, the compression platform was installed at the Thebaud complex.
The Sable Project is owned by the following companies:
ExxonMobil Canada Properties Ltd.|
Shell Canada Limited|
Imperial Oil Resources|
Pengrowth Energy Corporation|
Mosbacher Operating Ltd.|
The Sable Project is the largest construction project ever undertaken in Nova Scotia. We’re proud of what we’ve accomplished. We’ve established an infrastructure that will be the basis of our production efforts for the future. Those efforts are changing the face of the Nova Scotia economy, and providing an alternative energy resource to consumers throughout the Maritimes and the Eastern United States.
Here is a brief overview of our existing facilities.
Thebaud Processing Facility
The Thebaud platform is the hub of Sable’s offshore activity. Preliminary processing of the gas from the Thebaud wells, as well as gas from the existing satellite platforms – North Triumph and Venture – is done here and then sent through the pipeline to the Goldboro Plant in Guysborough County, Nova Scotia.
Accommodations Unit: 40 people
Water Depth: 29 metres
Distance to Goldboro Plant: 200 km
The Venture platform, second in size to Thebaud, does preliminary dehydration of the natural gas from its wells, and then transports it to Thebaud for further processing. Production on Venture is controlled by Thebaud.
Accommodations Unit: 24 people
Distance to Thebaud: 57 km
Water Depth: 22 metres
North Triumph conducts preliminary processing before transporting its natural gas to Thebaud.
Accommodations Unit: None
Distance to Thebaud: 35 km
Water Depth: 76 metres
The Alma platform developed the first Tier 2 field. The platform conducts preliminary processing before transporting its natural gas to Thebaud.
Distance to Thebaud: 50 km
Water Depth: 67 metres
Production from the South Venture field began in late 2004. The South Venture platform is similar in design to the existing platforms at North Triumph and Alma.
Water Depth: 23 metres
Goldboro Gas Plant
The Goldboro Gas Plant is located in Guysborough County, Nova Scotia and operates 24 hours a day, seven days a week.
Site size: 45 hectares
Processing capability: 17 million cubic metres per day
Point Tupper Fractionation Plant
Natural gas liquids are a by-product of the processing that occurs at the Goldboro Plant. These liquids are separated and transported via a buried pipeline to Point Tupper, near Port Hawkesbury on Cape Breton Island for fractionation. The liquids are separated into propane, butane and condensate. Daily, Point Tupper can produce enough propane to fill 63,000 20-pound barbecue tanks, enough butane to fill 11 million lighters, and enough condensate to produce all the gasoline needed for a car to drive around the world 515 times. The fractionation plant operates 24 hours a day, seven days a week.
Site size: 29 hectares7,000 barrels propane
Workforce: Approximately 20 people
Processing capability: 20,000 barrels of liquid per day
3,000 barrels butane
10,000 barrels condensate
