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.

A 2018 explosion at a natural gas well owned by an ExxonMobil subsidiary emitted more methane into the atmosphere than some countries do in a year, a new study using satellite data has found.

Why it matters: It's the first time methane from an oil or gas incident has been detected and quantified using data gathered by satellite. The study shows space technology could become a key tool in detecting leaks of methane — one of the most potent greenhouse gases.
