Over the past few years, the Rocky Mountain region has experienced explosive growth in drilling, especially in the number of natural gas wells. Benefiting from increases in gas price and new technologies, operators have embarked on a wave of development of gas resources that is breathtaking in magnitude, comprising increases of thousands of wells. While the region has previously experienced booms in drilling, this one has a different character. Natural gas resources are being developed at an unprecedented density, with wells spaced every 20, 10 or even 5 acres.
