Why the Persian Gulf has more oil and gas than anywhere else on Earth

The Persian Gulf has more oil and gas than anywhere else, a result driven by geology over tens of millions of years, according to the article. It cites more than 30 supergiant fields around the gulf, each holding at least 5 billion barrels of oil, and notes that regional wells can produce two to five times more oil per day than even the best wells in the North Sea and Russia. The piece attributes the region’s richness to rock factors that are at or near optimal levels for generating and trapping hydrocarbons, shaped by the collision between the Arabian Plate and the Eurasian Plate for about 35 million years. Historically, the region’s hydrocarbon presence was known long before the Persian Gulf formed at the end of the last ice age, with a modern oil discovery recorded in 1908 in western Iran. It compares the scale and productivity to places including West Siberia and the U.S. Permian Basin, but says none match Persian Gulf output and reserves.
