The first part of the process, the drilling and completion, is quite employment intensive. But even though that wellhead or those wells exist for many years, the employment continues for long-term job creation.
There have been economic studies cited in several jurisdictions in North America, such as the Haynesville project in Louisiana, where 50,000 jobs were created in one year and $6 billion of wealth has been created, and in the Barnett shale, which is the most active of the shale projects in North America, 130,000 jobs were created over a multi-year timeframe.
These aren't assumptions; these are actual studies that have been done by economists. The third one that I can refer you to is Marcellus shale in Pennsylvania, where over 57,000 jobs have been created in that state in the last couple of years with the shale development. These are long-term jobs.
