Shell halts Carmon Creek oil sands project in Alberta, Canada

Tar sands site had been slated to produce 80,000 barrels a day but lower global prices, cost-cutting and lack of infrastructure contribute to shelving

Royal Dutch Shell will halt construction of its Carmon Creek thermal oil sands venture in Canada due to "uncertainties" facing the project, including a lack of infrastructure.

The decision to stop the project in the western province of Alberta comes as Shell cuts costs and a shortage of pipeline capacity constrains growth in the Canada's oil sands industry.
