I was checking out Google now that it has changed its algorithms, and I am pleasantly surprised.
In the process I ran across the Bakken Oil blog again. It is, in fact, the first "real" hit on Google with the new algorithm when searching for "Bakken oil." That's pretty impressive.
As far as I can tell, that blog is also free of advertisements.
The site directed me to "Spare Capacity Theory" which puts things into perspective.
