Hi,  I was looking at a gas well on SONRIS and I have noticed on the Well Allowables

that Allowable and Potential are often the same. But this month I saw that on one line

it had dated 7/01/2012 12/31/2012 10052 10052, but then on the line above it with the same dates it had the allowable and potential at 0.  What do all these numbers mean? Please help.

Thanks,
