Which all gets away from my original point: the recent surge in fracking as an extraction method is a result of $100 oil, general deflation (aside from oil) actually is another driver to delay new exploration or new areas of production - delay means lower prices for the fixed equipment and the likelihood that temporarily reduced production will help raise oil prices. Almost no-one alive today has experience of deflation in a major economy, it will have the most peculiar effects on business decision making in general, and make businesses resistant to investment given that they will be very unsure on their returns.
Do you understand, the drilling rig count, went significantly high before we reached those prices?
