OPTI, in partnership with Nexen, is parented by Israeli corporation Ormat (who also own many shares in the ostensibly Canadian OPTI) and uses the worst climate changing form of procedure available-- borrowed from Ormat who patented it in historical Palestine as "Or Crude", called "cogeneration" in Canada. It's a procedure of burning the waste gunk from the bottom of a previously extracted barrel to power the operations of getting more bitumen.
