Exxon Valdez spill was about 258,000 barrels in size - so this one is at least twice as large
In a body of water many magnitudes larger, there will probably be some oily beaches and slow fishing for a while, but this shall pass. It’s mostly hype people.
The 1979 IXTOC I is the largest accidental spill in history, to date. The well was initially flowing at a rate of 30,000 barrels per day, which was reduced to around 10,000 bpd by attempts to plug the well. The IXTOC I accident was the biggest single spill ever, with an estimated 3.5 million barrels of oil released. Some estimates put the amount of oil released at over 200 million gallons. But the official estimate was about 150 million gallons.
