Frequently Asked Questions
Shale gas is natural gas trapped in hard dense deposits of shale formed from ancient sea basins millions of years ago.
The process of bringing a well to completion is generally short-lived, taking only 70 to 100 days for a single well, after which the well can be in production for 20 to 40 years. The process for a single horizontal well typically includes four to eight weeks to prepare the site for drilling, four or five weeks of rig work, including casing and cementing and moving all associated auxiliary equipment off the well site before fracturing operations commence, and two to five days for the entire multi-stage fracturing operation.
An incredibly small amount of seismic activity accompanies the hydraulic fracturing process; however the low level of seismicity has resulted in no cases of injury or property damage in over one million instances.
Yes, each well has layers of cement and steel casing to prevent groundwater leaks. Most wells are monitored with state of the art equipment.
Emissions from oil and gas activity fall under state and federal limits. Industry is working with the EPA to define New Source Performance Standards (NSPS) that will further reduce emissions.
