What is hydraulic fracturing in oil & gas field?
Hydraulic fracturing is a common technique used to stimulate the production of oil and natural gas. Typically, fluids are injected underground at high pressures, the formations fracture, and the oil or gas flows more freely out of the formation. Some of the injected fluids remain trapped underground. A number of these fluids, such as diesel fuel, qualify as hazardous materials and carcinogens, and are toxic enough to contaminate groundwater resources.
