According to Wikipedia, ,hydraulic fracturing, is “the widening of fractures in a rock layer caused by the high-pressure injection of chemicals with water.” It is this process that results in natural gas and oil to be recovered from deep shale deposits. Typically, the wells involved in the ,fracturing, process are in excess of 5000 feet deep.
