Thinking that the geology is no different is foolish.

Correct. However, you read more into it than I said. I didn’t say the geology of the permian is no different. All I said was that the the “permian deposits are not as beautiful/orderly as those in the eagle ford and baaken.”
And yet permian oil production is growing fast. To your point at least part of the reason for the fast growth is the sheer number of rigs in the Permian.
It helps, in my opinion, that the Permian basin is a long time area for oil production. Many areas did not require new leases, oil wells with minimal production kept old leases in force. For other areas, oil wells are not new idea and much of the people there are used to the idea. Lots of infrastructure still in place. That, combined with a large areas has made it easier for the number of rigs come in, or back in, for servicing the area.
