Ann: Southern Cooper Basin Gas Project - Update, page-8

Agreed 618... low to very low single digit. I get a pretty good match in my model at 1-2mD average perm.

The problem with perm this low is that it takes much longer to ramp up to max gas rate. But once it gets there it will basically run just about forever. They'll still get 6 bcf per well even at that sort of perm.

300 mscfd peak rate won't be adequate for commercialisation (even if it maintained that with no decline it's only 1 bcf over 10 years - clearly not enough when decline rate and discount factor come into play), but what they may have meant is that 300 mscfd from this well design may have given them enough confidence for commercial rates from improved well designs.

In particular at 1mD this sort of reservoir would be screaming for a lateral.
