The purpose of this study is to estimate the economic impact of the $200 billion (2011 dollars) in midstream investments that will be required to accommodate the development of natural gas, oil and natural gas liquid (NGL)1 resources from 2012 through 2035. Near-term estimates through 2013 and through 2016 also are developed. The estimated economic impact of these investments is measured in terms of employment creation, income generation, output, taxes generated and value added to the US economy and study regions.
