The impact of the Marcellus shale formation on domestic natural gas supply is difficult to overstate. The speed and volume in developing this formation is astonishing. In 2007, Marcellus supplied only 2 percent of domestic supply in the U.S. By the end of 2013 it accounted for nearly 20 percent of total supply. The EIA predicts the formation will produce an average of 15.9 billion cubic feet of gas per day in September, nearly a quarter of all U.S. production. If Marcellus had one constant trait, it would be that it has continued to prove ‘experts’ wrong or extremely conservative in their projections of the formation’s output.
Just how has Marcellus continued to grow at such a blistering pace? To start, the industry’s learning curve has been impressive. Marcellus natural gas production continues to grow despite a drop in rig count since 2012. Historically, natural gas volumes have responded to shifts in rig counts. Analysts have argued that it would be difficult for the industry to maintain production with a slowdown of drilling activity. The Marcellus has turned this logic flat on its face.
