Some vested interest group played a dirty hand in getting me, Mark Anthony, completely banned on Seeking Alpha. My previous articles are still there. But I bet they will ultimately remove all traces of them eventually...
My study shows that Bakken well declines MUCH FASTER than even Arthur Berman claimed. For example I summed up production from 3062 Bakken wells that has been continuously producing in all the months from May to Nov 2012, including 128 wells that only started in May 2012. That's the entirety of all wells I can find that has been producing continuously, but excluding a few that produced for a while and then shut down.
In May 2012, those existing wells produced at average of 506869 Barrels per day (BOE), with gas and oil production lumped together as Barrel of Oil Equivalence (BOE).
In Nov 2012, only six months later, these same 3062 wells produced at 353040 BOE/day. That's a drop of -30.35% in merely six months. That's averaging at -0.2% drop per day, or -5.9% drop per month, or -51.5% drop per year.
