Rockman, you see that first graphic Pops uses? Check out this document and let me know how many flat topped oil production rates you notice?
http://pubs.er.usgs.gov/publication/ofr20131109Next point, can someone please tell me why I believe ANYTHING someone says when they obviously aren't even aware of the seminal work on the topic, and how that guy doesn't give anyone equations for flat topped oil well production either?

Which by extension means, if someone doesn't even know how most wells produce naturally (because those who do reserve reports or do field and well production management certainly know the pressure maintenance configurations used to make a wells production rate do most whatever they want) then why in the WORLD would anyone take any conclusions they draw from such a flawed understanding of the reservoir dynamics involved?
To sum up, whoever made the original graphic couldn't even be bothered, or worse yet didn't know, how wells actually produce. On those grounds alone they probably can't be trusted to draw any conclusion of value from something they have already proven they do not understand.
