ExxonMobil Selects GBS To Develop Hebron Field Off Canada

ExxonMobil Corp. will develop the Hebron oil field offshore the Canadian province of Newfoundland and Labrador using a Gravity-Based Structure (GBS) that will recover more than 700 MMbbls of of oil, an increase versus earlier estimates.

Capital cost for the project, which is expected to begin oil production by the end of 2017, is estimated at $14 billion. The platform is being designed for daily production of 150,000 bbls of oil.

“Hebron is one of several large-scale oil developments that ExxonMobil will bring on stream in the next five years,” said Neil W. Duffin, president of ExxonMobil Development Company. “ExxonMobil will employ its expertise in Arctic development and project execution to develop this world-class resource in challenging operating conditions.”
Hebron’s development will provide significant benefits to the province, including employment for up to 3,500 people during construction in the province, and royalties and taxes to fund provincial infrastructure, social programs and services.

The project received regulatory approval from the governments of Canada and Newfoundland and Labrador in May.

The Hebron GBS consists of reinforced concrete designed to withstand sea ice, icebergs and meteorological and oceanographic conditions. The base will be designed to store 1.2 MMbbls of crude and will support an integrated topsides deck that includes a living quarters and facilities to perform drilling and production.

Front-end engineering and design was completed last year and significant progress has been achieved on detailed engineering. Cost estimates reflect advanced project definition and market and foreign exchange rates.

Construction of the GBS is under way at the project’s primary construction site in Bull Arm, Newfoundland and Labrador. Topsides fabrication is expected to begin later this year.
Hebron will be operated by ExxonMobil affiliate, ExxonMobil Canada Properties, which holds 36% equity in the project. Hebron co-venturers are Chevron Canada Limited (26.7%), Suncor Energy Inc. (22.7%), Statoil Canada (9.7%) and Nalcor Energy Oil and Gas (4.9%).

The Hebron field is located offshore Newfoundland and Labrador in the Jeanne d’Arc Basin more than 200 miles southeast of the capital of St. John’s and about 19 miles southeast of ExxonMobil’s Hibernia project. Water depth is 300 feet.
