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 second and third largest companies in general, with revenues of some 305 and 257 billion U.S. dollars, respectively. As of 2015, ExxonMobil was also the company with the highest market capitalization, only topped by technology giant Apple, but it was demoted to ninth place as of May 2017.
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.
