Oil & Natural Gas

Oil and gas are naturally occurring hydrocarbons consisting of a complex mixture of organic material of various molecular weights and other liquid organic compounds. Generally referred to as petroleum, they are found in geologic formations beneath the Earth's surface. The name petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is used in the manufacture of a wide variety of products.

Natural gas is primarily a mixture of four naturally occurring gases that have different molecular structures. Natural gas consists mostly of methane and contains less than 20% of ethane, butane and propane. Natural gas is used for electricity generation, heating, manufacturing and transportation. Chemical constituents - known as natural gas liquids, or NGLs - are extracted from natural gas to provide chemical building blocks for the manufacture of consumer products.
