The petroleum industry also uses sand. Under pressure, sand is injected into an oil well. The sand goes into the cracks and crevices where the oil is trapped. When the pressure is released, the sand helps hold the cracks open. When this process works, oil production can be increased greatly. The process is called sand-fracturing.
