The Railroad Commission released an updated well map in May. Since the March 15, 2012 version, the number of gas wells on schedule has only grown by 25, but the number of oil wells on schedule has surged by 422 to 1,376.

We're close to having 2,000 producing wells on record. Take into account the delays in reporting and we're likely well past 2,000.

The number of permits issued in the play jumped 381 to more than 4,000 over the past two months as well.

We're running at a blistering pace. 400+ oil wells in two short months is a substantial feat and with ~250 rigs running, we'll likely replicate the growth of the past two months many times over.

The increased pace of drilling and permitting is exactly why we're seeing higher future production estimates almost weekly.
