And in the expectation of continued large fluctuations?
I think that is too general a statement to be correct. Big drops in storage levels is a fluctuation.
I see storage capacity gets built, when the working spare capacity gets low enough to drive up the price to store oil. I'm not sure there is expectations that this condition is going to last long enough to pay off. I see greater pressure on pipeline and rail capacity to get built. There is price pressure to get inland produced oil to compete more with coastal refineries and further reduce imports of crude oil.
