Where are you getting the information that stop&#x2F;start is inefficient and costly for fracking? It&#x27;s less than conventional oil wells. I&#x27;ve found a significant cost of fracking is establishing the wells.<p>If the price goes up that much, fracking is viable and will happen. The only way fracking is out of the equation if when low prices keep it from being profitable. Fracking presently functions as a cap on the price.<p>If prices vary wildly, then there are strategies to deal with that, and the variation needs to be explained. How does it come down so rapidly? Assuming healthy economics, probably because of fracking.<p>It doesn&#x27;t make sense to say that market prices aren&#x27;t demand driven just because other costs and factors exist. If suppliers will lose money at a given low price because of costs, eventually supply decreases and prices rise, etc.
