Hydraulic ,fracturing, is a method to enhance oil and natural gas extraction from underground geological formations involving injection of a ,fluid, under high pressure in order to crack the rock containing the hydrocarbon. While the method is not new, its use has surged since being combined with horizontal drilling technology in the late 20 th century.
