Exxon launches oil production off Guyana's coast

ExxonMobil said Friday night that the company has begun oil production off the coast of Guyana, where the energy giant has made a string of huge discoveries in recent years.

Why it matters: Guyana is a major focus of Exxon's portfolio, and the development is slated to make the South American nation the world's newest substantial oil producer.
