Oil & Gas

Oil and gas are also important for the number of jobs they provide. Tens of thousands of people work in the oil and gas industry. The oil and gas industry is usually divided into three major sectors: upstream (or exploration and production- E&P), midstream and downstream. The upstream sector includes searching for potential underground or underwater crude oil and natural gas fields, drilling exploratory wells, and subsequently drilling and operating the wells that recover and bring the crude oil or raw natural gas to the surface. Midstream Operations are sometimes classified within the downstream sector, but these operations compose a separate and discrete sector of the petroleum industry. Midstream operations and processes include the following: Gathering, Processing/refining, Transportation, Storage, Technological applications. We now produce natural gas from buried coal seams, oil and natural gas from deep deposits located miles beneath the surface of the earth, and in the deep ocean, hundreds of miles offshore and in water depths greater than 10,000 feet. Some petroleum industry operations have been responsible for water pollution through by-products of refining and oil spills. The industry is the largest industrial source of emissions of volatile organic compounds (VOCs), a group of chemicals that contribute to the formation of ground-level ozone (smog).The combustion of fossil fuels produces greenhouse gases and other air pollutants as by-products. Pollutants include nitrogen oxidessulphur dioxidevolatile organic compoundsand heavy metals. Oil and gas are often found far away or under the sea. They have to be transported to an oil refinery. This is often through a pipeline or in a tanker
