Notice the word "legacy." The Permian has been producing for, like, a hundred years. At this point those legacy fields have little to no bearing on what the tight oil zones can do, and thus, the Permian as a whole. It's now pushing 1.8 million barrels/day and you're worrying about some old fields that are now declining 60,000 barrels/day. Big deal.
Notice the definition of the word "legacy":
A new well is defined as one that began producing for the first time in the previous month. Each well belongs to the new-well category for only one month.
New wells are new for only a month, then they become a legacy well. So look at the decline in legacy wells in 2007, only 10mbd decline on 800mbd of production.
Today, the decline is over 5 times that amount and production has barely doubled. What does that tell you about the longevity of all those new wells?
I'd guess that those old wells will still be pumping out their 10b/d long after the tight wells are filled with cement and the drillers that made a living drilling wells and extracting investor's cash rather than extracting oil are drinking rum and watching a Cuban girl roll them a cigar on her firm, tan thigh.
