context_page_description: Petroleum in the United States has been a major industry since shortly after the oil discovery in the Oil Creek area of Titusville, Pennsylvania in 1859. The industry includes exploration, production, processing, transportation, and marketing of natural gas and petroleum products. As of 2019, the United States is the world's largest oil producer. The leading oil-producing area in the United States in 2014 was Texas, followed by the offshore federal zone of the Gulf of Mexico, North Dakota and California.
  The oil industry extracted a record high 4.46 billion barrels of crude oil in the United States in 2019, worth an average wellhead price of US$55 per barrel. 2019 oil production was more than double the production ten years earlier, in 2009.
  US Natural gas production achieved new record highs for each year from 2011 through 2014. Marketed natural gas production in 2014 was 74.7 billion cubic feet per day, a 44% increase over the rate of 51.9 billion cubic feet per day in 2005. Over the same time period, production of natural gas liquids increased 70%, from 1.74 million barrels per day in 2005 to 2.96 million barrels per day in 2014.
context_section_description: The United States petroleum refining industry, the world’s largest, is most heavily concentrated along the Gulf Coast of Texas and Louisiana. In 2012, US refiners produced 18.5 million barrels per day of refined petroleum products. Of this amount, 15 percent was exported. As of 2012 the US was the world’s second largest net exporter of refined petroleum products.
