It does sound like you've researched things, and good on you. I hope ADN publishes you. Now regarding the oil companies predictions, I always take them with a block of salt, especially in a low price oil climate. 
How about this: rather than making financial strategies based on hypotheticals, establish a budget strategy and revenues based on today's situation. Maybe it's PF restructuring, maybe it's taxes, whatever. But when they're implemented, include a trigger that mandates that when oil revenues reach a specified point , the other measures sunset. That way we've taken a conservative approach that helps to wean us off of the oil teat.
