Outstanding!!! And all the ignorant, cherry picked, bad assumptions and industry and economic ignorance in the paper? What is that derived from? Study time at Lyndon LaRouche's school for the waywardly stupid?

Where in my career as a reservoir engineer have I needed your equation? Ever?

Need some more room to maneuver? Fine. Where in my career as a production engineer have I needed your equation? Ever?

Need some more room to maneuver? Fine. Where in my drilling and completion career have I needed your equation? Ever?

Pick your sub-specialty, I've worked in all 3, a little more in 2, but I still consult across all 3.

Still too difficult? Fine. How about this? You represent your "model/system/can't get reviewed paper" as industry representative, which implies something we already know to not be true (that you are familiar with the industry).

Perhaps you would prefer to discuss how anything I have ever done in the oil field would be improved by knowing your equation? So. How can anything petroleum engineers do in the field, office, rig or frack van be improved by knowing your equation?

If you are willing to admit that your equation is meaningless at the practical petroleum engineering level, that is okay. Then we can discuss if it is meaningful from a scientific or economic perspective in general.
