U. Calgary analysis of energy balances and emissions of SAGD oil sands production finds need for improved processes; some operations not thermally efficient or net generators of energy

Green Car Congress

Plot of cumulative steam-to-oil ratio (cSOR) vs. ratio of energy produced in form of chemical energy contained in bitumen if combusted to energy injected in form of steam (75% efficient steam generation). From Gates and Larter (2013). One of the key challenges in producing bitumen and heavy oil is their high, variable viscosity.

Average carbon intensity of oil sands production has dropped ~36% in last 40 years; still 12-24% higher than conventional oil CI

Green Car Congress

In situ production began in 1974, so no value is computable for 1970. The carbon intensity (CI) of Alberta oil sands production has significantly decreased over the last 40 years, according to a new study by a team from Stanford University published as an open access paper in the journal Environmental Research Letters.

Joint Canada/Alberta Implementation Plan for Oil Sands Monitoring begins summer air monitoring project

Green Car Congress

A comprehensive environmental field study to gather information on air contaminants in the Wood Buffalo region in northeast Alberta, Canada (home to major oil sands projects) will occur from 12 August to mid-September 2013. Evaluate high-resolution air quality models for use in the oil sands region. Earlier post.).
