CO2 intensity rises in Statoil operations: company report

English.news.cn   2014-04-08 21:31:59

OSLO, April 8 (Xinhua) -- Carbon dioxide (CO2) intensity in Statoil operations rose from 55.6 kg CO2/barrel in 2012 to 69.7 kg CO2/barrel in 2013, said the Norwegian energy giant Statoil on Tuesday.

But its 2020 target of 25 percent CO2 intensity reduction remains firm, said Statoil in the 2013 Oil Sands Report issued on Tuesday.

The CO2 intensity in 2011 was 72.7 kg CO2/barrel. The increase in CO2 intensity was attributed to facility maintenance and integration of pilot technologies to reduce long-term CO2 intensity.

More steam was utilized in 2013 when a fourth steam generator was added to support new well pads and current production wells, the report said.

Statoil also experienced an imbalance in the reservoir after a planned maintenance period. As a result, production levels were lower and steam use was higher than usual, a major operational factor which impacts the overall CO2 intensity rate.

CO2 intensity in Statoil operations is expected to decline as operations normalize and additional technology is introduced, said the Statoil report.
