As the U.S. and Europe cut back purchases of Russian oil, and energy traders shun it for fear of sanctions, the search is on for other sources. Attention has focused on Iran and Venezuela, both of which are led by governments that the U.S. sought until recently to isolate. But emerging and less-developed producers could also play roles.
Among the world’s many oil-producing countries, a few are positioned to jump the list and become increasingly active. They include the West African nation of Ghana (No. 33), along with Guyana (No. 42) and Suriname (No. 69), two small adjoining countries on the north Atlantic coast of South America. All three nations have become oil producers within the past 12 years, working with large companies like ExxonMobil, Tullow Ltd, Chevron, Apache, Total and Royal Dutch Shell.
