I haven't had the chance to thoroughly review this yet, but here is a paragraph from the executive summary:
Estimates of overall economic impact for the 21-county area in 2013 top $87 billion, up from $61 billion in 2012. For 2023, the 21-county impact is estimated to exceed $137 billion, far higher than the $89 billion forecast for 2022 that we reported in the March 2013 economic impact study. The rationale for the upward revisions (as mentioned above) is due to the way the Eagle Ford continues to exceed expectations in terms of production. In addition, new manufacturing projects associated with the natural gas renaissance in the U.S., as well as new processing, refining and port facilities are factors driving increases in the economic impact statistics.
