Saudi Arabia could be next to use new technology to get at currently trapped gigantic reserves of oil and gas. A small pilot project about to get under way is the energy market equivalent of a moonshot, but it could allow a Saudi fracking boom to move one step closer to reality.
All over the world, there are naturally fractured oil and gas reservoirs called carbonate formations, and no region has as much oil and gas trapped in carbonate formations as the Middle East. Carbonates are areas of sedimentary rock—limestone, for instance—that contain many natural cracks inside them.
Carbonate formations are estimated to hold 60 percent of the world's oil and 40 percent of the world's gas reserves. In the Middle East, roughly 70 percent of oil and 90 percent of gas reserves are trapped in the carbonate, according to oil services giant Schlumberger.
