Be that as it may, my database shows that 49 permits issued in 2010 were canceled or have expired.
For 2010, I have data for 977 permits (off confidential list but no data; total depth reached; plugged or producing, IP). That means there are still 705 permits that are still outstanding, either drilled and on the confidential list, or not even spudded yet. That's more than all the permits issued in 2009, 2007, or 2006.
