Certainly potential to make good money for the next few years at least. Beyond that is anyone's guess.

If BRK management want their shares to be priced as if they are a producer, they need to start behaving like a producer and that means paying dividends - or at least making a commitment to pay dividends. Then people can invest with at least some prospect of earning a return.

If their plan is based on $45 a barrel and they are earning $90 a barrel why not reward shareholders with a dividend? That would be a sure fire way of getting the share price moving up again.
