Pennsylvania Grade Crude Oil

Pennsylvania Grade Crude Oil is a type of sweet crude oil (sweet crude oil), found primarily in the Appalachian basin in the Marcellus Formation in the states of New York, Pennsylvania, Ohio, and West Virginia, and takes its name for the state of Pennsylvania, where it was first extracted in 1859 from the Drake Well. The area's Pennsylvania Grade Crude Oil has superior qualities and is free of asphaltic constituents, contains only trace amounts of sulfur and nitrogen, and has excellent characteristics for refining into lubricants. The success of drilling for oil at this well led to "an international search for petroleum, and in many ways eventually changed the way we live." There is archaeological evidence that Native Americans harvested "the oil for medicinal purposes by digging small pits around active seeps and lining them with wood" at least as far back as 1410 AD. European settlers skimmed the "oil from the seeps and using the petroleum as a source of lamp fuel and machinery lubrication."
