A Reader’s Chart Of The Week: Crude Oil

 | Apr 25, 2016 01:30AM ET

One of the things I like about posts like the Chart of the Week is that it gets people to think, share and collaborate. It can be a bit of an echo chamber sometimes, so we welcome other opinions and feedback about our work. This chart of the week comes from reader Bradley Parkes, former investment banker and current geologist (check out blog too ).
