Statoil Uses New Oil-Sands Technology Amid Rising Carbon DioxideSource: Bloomberg | 10 April 2014
Statoil expects to decrease carbon-dioxide emissions per barrel from its Canadian oil-sands projects by 20% within 6 years, responding to environmental criticism of the crude production method.
Statoil’s division in Alberta produces bitumen, a sticky form of oil that’s softened before extraction with steam created in natural-gas-powered generators. Norway’s biggest energy producer said yesterday that carbon intensity from its oil-sands operations rose 25% from a year earlier to 69.7 kg of carbon dioxide per barrel.
Statoil is applying solvents to its steam-assisted techniques and will use valves to better direct steam to areas that need it, Staale Tungesvik, president of Canadian operations, said. The Stavanger-based company also is considering different drilling techniques and more efficient water-recycling processes.
“The difference between oil sands and conventional oil production is that we use gas to heat water to create steam, so the footprint of CO2 is very much out of the generation of steam,” Tungesvik said. “We believe that we have identified technologies that will help us reach our target of reducing CO2 intensity by 20% by 2020.”
