UPDATE 2-Athabasca cuts output as Alliance gas pipeline shutdown continues

The Athabasca cut equals 4,200 barrels of oil equivalent a day (boe/d), and comes after Alliance declared force majeure on its 2,400-mile (3,850-km) pipeline after poisonous hydrogen sulphide entered the system.
The mainline delivers gas and natural gas liquids from Western Canada and North Dakota's Williston Basin to the Chicago market.
It accounts for about a third of Canada's daily net exports to the United States and the shutdown is expected to last several more days.

Alliance began flaring at its mainline block valve station near Arcola, Saskatchewan, on Sunday and will add incremental flares at its Alameda compressor station downstream, the company's manager of commercial and government affairs, Tony Straquadine, said.
"We will continue to work to measure gas as we are flaring it to safely remove the hydrogen sulphide from our system," Straquadine added. Continued...
