A picture of oil depletion

To a lay-person like me, I kinda understand how the oil depletion occurs, but a picture really helps to grok the story.

A picture of depletion

The picture itself is a little confusing, until you read the explanation.

It's an underground scan of an oil field, the Abqaiq oilfield in Saudi Arabia. The blue area is water that's been pumped in to help extract more oil, the red area is natural gas, and the little slice of green is the remaining oil. Disturbing, isn't it, how when that field was untapped the whole thing woulda been green, but all that's left is that little bit.
