What Is Shale Oil? - The Balance

Shale Oil Explained. Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the rock formations that contain the layers of oil in a process known as "fracking." Learn how shale oil works, its pros and cons, and how it compares to crude oil.
