Every day, I update my data base of wells reporting IPs. I generally do not have to open up the database of permits in 2009 (or before). Most of the updates are for permits issued in 2011 and in 2010, and even those in the latter are dwindling in number. It is very, very unusual to have to open up the 2009 database to record a new well.
Operators appear to be very "current" on their permits.
