US Natural Gas Well Completion data I found this interesting:
"The number of total gas wells completed continued to decline in both the fourth quarter of 2012 and in year to date comparisons, despite an uptick in exploratory gas drilling. In the year to date comparison, gas well completions have decreased 26% from 2011 (13,128 to 9,752 wells)."
and this years data:
Natural gas well completions in 2013 declined with 20 percent fewer wells than 2012, according to the report. Total number of wells completed in 2013 remained relatively unchanged with a decrease of 1 percent from 2012, while total footage drilled increased 4 percent."
