Ever since the U.S. shale revolution took flight in 2008, it’s been a consistent theme: not just rising natural gas production but also rising proven natural gas reserves. In fact, over the past decade, the U.S. Department of Energy reports that our proven gas reserves have ballooned nearly 85% to almost 450 trillion cubic feet (Tcf). It’s all turned the previous pre-shale notion that reserves were dwindling and production was in permanent decline on its head.
