Marcellus Shale Videos
The following is a collection of video clips collected from across the internet relating to the Marcellus shale formation, directional drilling, hydraulic fracturing and related issues.
Fracking The Marcellus Shale.
In the process of fracking a Marcellus shale well, some 800,000 gallons of water and sand are pumped deep underground into the shale rock strata.
This is a one time process which is done after the well is drilled. The subject of fracking or a frac job is causing a lot of controversy in the region. Much of the mistrust of oil and gas drilling stems from the legacy of environmental damage in the region done by coal companies. If the government mandated safety measures are followed, including properly cementing and testing the well prior to hydraulic fracturing, no harm to any water bearing formations above the Marcellus shale will occur. The gas bearing portion of the Marcellus shale is far below water bearing aquifers. With proper regulation as well as education of the public on the process, of the industry will hopefully gain the trust of the community. Natural gas production and exploration can occur with minimal impact to the environment, as has been demonstrated in the heavily populated Dallas - Fort Worth metroplex where Barnett shale drilling has been occurring since the 1990's. As an oil and gas extraction technique, "fracking" has been around for over sixty years.
The following video about hydraulic fracturing was produced by Chesapeake Energy. It shows the process that they used to frack or "frac" wells in the Marcellus shale formation. The process used by other oil and gas companies to drill and frac Marcellus shale wells may be slightly different but this is a good illustration of how the process is typically done by most oil and gas companies. Note the large distances involved between freshwater aquifers and where the frack job occurs.
How Natural Gas Wells Are Drilled Horizontally
The following is an illustration of how a natural gas well is drilled horizontally, as is done in the Marcellus shale formation. While each horizontal drilling situation is unique this video gives a simple example of how directional drilling is done in most cases. Note that several wells can often be drilled from one pad location, reducing the environmental impact of multiple drilling sites.
Reclaiming Frac Water In The Marcellus Shale
The subject of water use for frac jobs in the Marcellus shale is also very controversial. Many of the large operators are making efforts to recycle as much of the used water as they can for re-use, rather than pumping it in deep injection wells. Here is another video by Chesapeake Energy showing how they reclaim Marcellus shale frac water.
How The Marcellus Shale Is Creating Jobs
Penn State University's Larry Michael discusses the need for job training for future Marcellus shale jobs. There will be thousands of direct and indirect jobs created as a result of gas production in the Marcellus shale.
API chief economist John Felmy discusses the importance of the Marcellus shale formation.
