ABOUT A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick. The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it both to move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane. Forms of derricks are commonly found aboard ships and at docking facilities. Some large derricks are mounted on dedicated vessels, and known as floating derricks and sheerlegs. The term derrick is also applied to the framework supporting a drilling apparatus in an oil rig. The derrick derives its name from a type of gallows named after Thomas Derrick, an Elizabethan era English executioner. 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 petroleum industry includes exploration for, production, processing (refining), transportation, and marketing of natural gas and petroleum products. As of 2008, the U.S. was the world's third-largest oil producer (after Saudi Arabia and Russia), producing 8.5 million barrels of oil and natural gas liquids per day. The leading oil-producing area in the United States in 2014 was Texas (3.17 million barrels (504,000 m3) per day), followed by the federal zone of the Gulf of Mexico (1.40 million barrels (223,000 m3) per day), followed by North Dakota (1.09 million barrels (173,000 m3) per day) and California (0.50 million barrels (79,000 m3) per day). In 2015, US production of crude oil rose to 9.48 million barrels per day, the highest annual rate since 1972, and an increase of 90% from the 2008 production of 5.00 million barrels per day. On a monthly basis, however, US production peaked in April 2015 at 9.63 million barrels per day, then declined due to lower oil prices to 8.74 million barrels per day in August 2016. 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. In April 2015, natural gas was produced at the rate of 79.4 billion cubic feet per day. In 2014, petroleum and natural gas were the two largest sources of energy in the U.S., together providing 63 percent of the energy consumed (oil provided 35 percent and gas 28 percent). In 2008 the United States consumed 19.5 million barrels (3,100,000 m3) per day of petroleum products, of which 46 percent was gasoline, 20 percent diesel fuel and heating oil, and 10 percent liquefied petroleum gas. In 2015, the U.S. imported 24% of the petroleum it used, the lowest since 1970. The largest sources of U.S. imported oil were: Canada (40%), Saudi Arabia (11%), Venezuela (9%), Mexico (8%), and Colombia (4%).
