According to a report in the oil and gas quarterly, "Alberta Oil," two applications by Imperial Oil (Exxon-Mobil) for Oil Sands developments have been turned back because of the amount of greenhouse gases that will be generated, and the quantities of water required.

Alberta has legislated greenhouse gas reductions (GHG) of 12% for companies that have been in operation for eight or more years. It is a start, but many regard it as a token reduction. New facilities are granted "a proportional reduction in emissions intensity targets, starting at two percent per year beginning in the fourth year of operation."
"At the time of passing, Bill 3 affected approximately 100 facilities that collectively produce about 70% of total GHG emissions in Alberta."
Credits are allowed.

A proposal for reducing greenhouse gases from tar sands operations would see the gases pumped into the Devonian reef rock underlying much of the tar sands. I have not seen feasibility studies.

Interest in nuclear facilities as an energy source for tar sands production is increasing, and a proposal is expected soon.

The magazine is a slick production, subscription $10/copy. They use a new word, "advertorials," to characterize informational articles submitted by companies offering services (e. g., one from Halliburton about new products and services offered to the industry).

Total, the French oil giant, has placed ad adv. advising of their continued search for new oil reserves. - "But because oil is precious, it will be vital to focus its usage in those areas where it is hardest to replace: in transportation and petrochemicals."
