Common Uses for Barium Barium Sulfate in Oil Production Barium Sulfate is primarily used when drilling for new oil wells which is by far the most common use for is combined with water and some other minerals to create drilling mud This mud gets pumped into the drilling holes and because of its weight it helps to prevent the oil from exploding out into the environment a
