Oil shale is not exclusive to the U.S.A.

I believe it requires specialized equipment to find it, however.

Perhaps the reason Oil Shale is big in the USA is because the USA has more of it than the rest of the world ?
Maybe other countries do have it but there is so little of it that it's not worth the capital cost to go after it.

You are correct. China has the largest holdings in the world. The U.S. has the lead in exploration technology and knowledge - after all we started the oil industry, from exploration and production to refining. That leadership is something most politicians don’t ever appreciate. It’s a leadership lead as wide as our IT technology lead. So you can bet that as China and others seek to use their new-found reserves, they will turn to U.S. companies for help.
