We have two examples of actually lowering the steam-oil ratio.
I referred earlier to wedge well. I believe we have about 36 of these wedge wells now working in Foster Creek. Each of these wedge wells is producing about 800 barrels per day of incremental oil with little or no incremental steam, so that helps to reduce the amount of steam we produce as we're producing oil.
I also referenced in my remarks our solvent-aided process. We have one test well operating right now, I believe. We think we can get the steam-oil ratio down below 2 by using butane in place of some steam.
