According to a piece in the Wall Street Journal, the U.S. energy boom is not about to run out:
The number of rigs drilling in the U.S. is basically flat, but production is rising. The federal Energy Information Administration calls this "drilling productivity" and says it is showing no sign of slowing.
Lynn Westfall, the EIA's director of energy markets and financial analysis, points out that the rig count in South Texas' Eagle Ford Shale "has not changed since 2012, but the production per new well has doubled."
Innovation makes the difference. The federal government recently predicted that oil production would rise through 2019 and then flatten off. But a second scenario in the report assumed that extraction technology would continue to improve, leading crude output to rise through 2040, if not longer.
