What is oil and gas industry?
Oil and gas provide the world's 6.9 billion people with 60 percent of their daily energy needs. The other 40 percent comes from coal, nuclear and hydroelectric power, "renewables" like wind, solar and tidal power, and biomass products such as firewood. As fuels, they keep us warm in cold weather and cool in hot weather; they cook our food and heat our water; they generate our electricity and power our appliances; and they take us by car, bus, train, ship or plane to places near and distant. We all feel the economic pinch when the prices of gasoline, home heating fuel or electricity increase sharply, even though in many developed countries, they still cost less than some brands of bottled water. As petrochemical feedstock’s, oil and gas are the raw materials used to manufacture fertilizers, fabrics, synthetic rubber and the plastics that go into almost everything we use these days, from toys to personal and household items to heavy-duty industrial goods. The oil and gas industry, commonly called the petroleum industry includes the global processes of exploration, extraction, refining, transporting (often by oil tankers and pipelines), and marketing petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol). Petroleum (oil) is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics. Petroleum is vital to many industries, and is of importance to the maintenance of industrial civilization in its current configuration, and thus is a critical concern for many nations. The world consumes 30 billion barrels (4.8 km³) of oil per year, with developed nations being the largest consumers. The United States consumed 25% of the oil produced in 2007. How oil and gas is drilled for?

Whether employed directly by an oil company or under contract from a private firm, geologists are the ones responsible for finding oil. Modern oil geologists also examine surface rocks and terrain, with the additional help of satellite images, Modern oil geologists also examine surface rocks and terrain, with the additional help of satellite images, or finally, and most commonly, they use seismology, creating shock waves that pass through hidden rock layers and interpreting the waves that are reflected back to the surface. Although the entire process and equipment required drilling for and acquiring oil and gas I complicated, we feel it is necessary to point out the major components which are directly related to our study of occupational hazards. A short description of an oil rig components and process is detailed below: * Rotating equipment - used for rotary drilling

* Swivel - large handle that holds the weight of the drill string; allows the string to rotate and makes a pressure-tight seal on the hole * Turntable or rotary table - drives the rotating motion using power from electric motors * Drill bit(s) - end of the drill that actually cuts up the rock * Casing - large-diameter concrete pipe that lines the drill hole, prevents the hole from collapsing * Circulation system - pumps drilling mud, mixture of water, clay, weighting material and chemicals, under pressure to extract oil. *...
