Oil currently amounts for just under a third of the world’s energy, and oil companies have invested a great deal in exploration and overseas projects to ensure they can continue to help meet global energy demands.
About 6000 kinds of products and goods are also made from oil, ranging from household goods to pharmaceutical products and the automotive industry. This commercial utility means the demand for oil extends beyond the energy sector, and has ensured that oil companies have an important role throughout society.
