Kosmos Energy Ltd.
A Dallas-based oil and gas company that hunts for and produces crude oil and natural gas in deep waters off the coasts of Africa and South America. Founded in 2003 by a team of veteran explorers backed by private-equity money, it made its name discovering Ghana's first commercial oil field, the Jubilee field — a story told in the documentary "Big Men." Its name comes from the ancient Greek word "kosmos," meaning order and the universe.
