Exxon Mobil Corp said this week it ended natural gas production at its Sable Offshore Energy Project off the coast of Nova Scotia, Canada by Dec. 31:
* Sable had been producing gas since 1999. It was Canada's first offshore gas project, according to Exxon's website.
* Sable is made up of seven offshore platforms with 21 wells and 340 kilometers (211 miles) of subsea pipeline.
* Gas from the pipeline was transported via the Maritimes & Northeast pipeline to customers in Nova Scotia, New Brunswick and the US Northeast.
* Monthly production at Sable peaked in December 2001 at 517,802,000 cubic meters, or about 18.3 billion cubic feet, and has been mostly declining since, according to data from the Canada-Nova Scotia Offshore Petroleum Board.
* One billion cubic feet is enough gas to fuel about 5 million US homes for a day.
* In November 2018, monthly production at Sable was just 55,314,000 cubic meters, according to the Offshore Petroleum Board.
* Exxon, which operates Sable, said on its website the project is owned by units of Exxon (50.8 percent), Royal Dutch Shell Plc (31.3 percent), Imperial Oil Ltd (9 percent), Pengrowth Energy Corp (8.4 percent) and Mosbacher Operating Ltd (0.5 percent).
* The Sable shutdown followed the closure of Nova Scotia's other offshore gas field in May 2018, Encana Corp's Deep Panuke project. Encana started producing gas at Deep Panuke in 2013.
