As this organic-rich layer accumulated, it created a dense, soupy mixture that would eventually be transformed by heat and pressure, a critical step in learning how is crude oil formed. The immense weight of newer layers compacted the material, squeezing out water and turning the remains into a fine-grained sedimentary rock called shale.

It travels until it encounters a non-porous barrier, such as salt or dense clay, which stops its ascent. This organic sludge was the primary ingredient that, over geological time, would become the basis for how is crude oil formed.
Crude oil is a fossil energy source that powers modern industry, yet its origins lie hundreds of millions of years in the past. This trap, often capped by an impermeable rock layer, is where the oil accumulates into a reservoir.
