About OPTIOPTI Canada Inc. is a Calgary, Alberta-based company focused on developingmajor oil sands projects in Canada. Our first project, the Long Lake Project,plans for approximately 72,000 barrels per day (bbl/d), on a 100 percentbasis, of SAGD (steam assisted gravity drainage) oil production integratedwith an upgrading facility. The Upgrader uses our proprietary OrCrude(TM)process, combined with commercially available hydrocracking and gasification.Through gasification, this configuration substantially reduces the exposure toand the need to purchase natural gas. On a 100 percent basis, the Project isexpected to produce 58,500 bbl/d of products, primarily 39 degree API PremiumSweet Crude (PSC(TM)). Due to its premium characteristics, we expect PSC(TM)to sell at a price similar to West Texas Intermediate (WTI) crude oil. TheLong Lake Project is a joint venture between OPTI and Nexen Inc. (Nexen). OPTIholds a 35 percent working interest in the joint venture. Nexen is the soleoperator of the Project.
