Top global oil and gas companies
The oil and gas industry is one of the largest industries worldwide. This sector is involved in exploration, extraction, refining, transport and marketing of these commodities. Many industries are extremely dependent on oil and gas products, mostly in the form of energy fuels or raw materials for chemical products.
Oil and gas companies are among the world’s largest corporations. Sinopec (China Petroleum & Chemical Corp) and Royal Dutch Shell are the world’s fourth and fifth largest companies in general, with revenues of some 294 and 272 billion U.S. dollars, respectively in 2016.
Most of the top oil and gas companies are multinational corporations involved in operations all over the world, generating hundreds of thousands of jobs. On the other hand, these companies are often exposed to criticism because of their involvement in cases of severe environmental pollution.
