Yes, I am definitely the Guru of the Illustrated WAG!
Thanks for the prompt T. I hadn't done this in a while.
Here is my same old chart showing my predictions from a couple years ago with updated prices. (WTI was anomalous for a couple of years, decoupled from the "real-er" waterborn price)

Wow, I suprise myself!
Is that erie or what?
Brent has touched the $120 Econo Ceiling 3 time and dropped back to the orange Demand Destruction line. The green "Depletion/supply price floor/etc" line has more or less crossed the Red Econo Ceiling Line, the price dropped to the oranged "Demand Destruction" line just as predicted!
For those new to this bit of blather, back in 2010 or 11 sometime, I noticed the price was moving exactly like it had in the '04-'06 period - the 2 green lines are dups, exactly the same angle. To my little brain that meant something so I extended the second green line (starting from 2009) into the future and drew the "Demand Ceiling" line sort of arbitrarily at $120, figuring it took a while for higher prices to kill demand in '08 but that that would be the price point that stopped growth - both economic growth and price growth.
My question was, what would happen when the "cost" floor (green line) crossed the Economic price ceiling (red line). I guessed that rather than increasing forever as per everyone, oil prices could only rise to some level - $120, then as they eroded the economy they would become more and more unstable starting and stopping drillers but the trend would be lower and lower. That is the light orange line.

Bow down mortals, I wield the power of PShop!
P.S. I guess I can't let my head get too big, I dropped from 3rd to 11th place in the brent game, lol Cog, Auntie, Midessa are 1,2,3 right now.
