If they are counting Kerogen and not just oil already cooked out of the rock, 2% may be too high of all petroleum.
If they are only talking about crude oil similar to what is in production today 5%~15% is probably in line, but can vary greatly between fields.
What the article seems to leave out is how the production rates in most EOR systems is far lower than the initial production. And the cost per barrel is far higher to produce.
It is a fairly reliable source for production, but it is not cheap and fast. It will happen, but it will reduce the falling rate of production, not create a new production boom. But it is a great source for continuing jobs.
This second phase, could that possibly include drilling in the Spearfish Formation near Bottineau? Do you have any insight?
I read a Sep 2013 article where Lynn Helms was interviewed and it stated: “In the Spearfish formation near Bottineau, N.D., one operator has applied for spacing units that would allow the operator to drill roughly 400 wells.”
