Today about half of the oil sands production is upgraded into synthetic crude, based on 2011 figures. So it's about 860,000 barrels a day. It's projected that by 2020 that will rise to about 1.4 million barrels per day that would be upgraded. Those numbers are based on current proposals that exist within the regulatory frame and on public knowledge that companies have. Of course companies choose to increase or decrease and invest in capital to provide for upgrading depending on market conditions. So for synthetic crude, there is a certain marketplace in North America and that market, in terms of which refineries desire that crude, varies and depends and grows and shapes as investments and infrastructure like refining happen.
So it is projected to grow from about 860,000 to 1.4 million.
