J curve analysis

[jackosieves]

Can someone briefly explain to me why the loading J-curve of a gas well will show a decrease in minimum rate for stable flow as the WGR gets higher? I'm having a hard time seeing why.

What software are you using? In ProdOp (from PLTech, LLC) the line doesn't move with changing WGR. When I look at Turner's arithmetic I don't see anything that could be tied to a WGR (I think that using absolute densities instead of mass-weighted densities is a shortfall in the calcs).

I am using ProdOp. I've been playing around with it and noticed that as I change the WGR (bbl/MMscf) to a higher ratio that the loading/J curve (Min BHP) moves to the left (lower rate). The calculated critical rate remains the same.
