What is Hydraulic Fracturing?

Hydraulic fracturing is an oil and natural gas production technique that involves the injection of millions of gallons of water, plus chemicals and sand, underground at very high pressure in order to create fractures in the underlying geology to allow natural gas to escape. The sand is used to keep the fractures open and allow oil or gas to flow more efficiently.  Hydraulic fracturing is commonly used in many types of geologic formations such as coalbeds, shale plays, and previously-­drilled wells to further stimulate production.
