The article  "What's new at the tar sands?" by Dave Cohen ASPO-USA is an interesting read.  In my opinion it illustrates why Connacher's purchase of Luke Energy to mitigate potential natural gas increases was so important and in hindsight such a brilliant strategic move.  The article can be found at either at  http://www.energybulletin.net/38716.html or http://www.aspo-usa.com/index.php?option=com_content&task=view&id=291&Itemid=91
