I don’t think that is a great change from our existing conventional wells. The later years that is.
The United States has an estimated 771,000 marginal wells in production - about 410,000 oil and 361,000 natural gas wells.

You are missing the entire point:
The very nature of these wells, with long laterals, fracced into extremely tite formations, causes very prolonged periods of time to occur to get much production decline.
Most conventional strippers are not the same. They are in more permeable formations and are vertical. Very different mechanisms of production.
As an example: I observed a Bakken well that produced +10 years and afterwards producing at low rates that had a well that encountered virgin pressure only 100’ away from the wellbore.
We are talking about massive pressure differentials within a horizon that causes oil to ‘bleed’ into a fracture system almost constantly, with a well suffering little observable decline.
A marginal unconventional horizontal, stage-fracced well is a completely different animal than most of the wells currently classified as stripper.
