Burial and Diagenesis: Turning Mud into Shale Over time, the accumulation of sediment turned the organic muck into rock. Migration and Trapping: The Birth of a Reservoir Once formed, the crude oil is not static.
From Crude Oil Formation to Refining Processes
When these creatures died, their remains settled on the seabed, mixing with sediment and becoming part of a nutrient-rich muck. The immense weight of newer layers compacted the material, squeezing out water and turning the remains into a fine-grained sedimentary rock called shale.
This allowed the soft tissues to be preserved and buried under layers of mud and silt. Crude oil is a fossil energy source that powers modern industry, yet its origins lie hundreds of millions of years in the past.
From Crude Oil Formation to Refining: Producing Gasoline and Diesel
From Reservoir to Refinery: The Final Stages After millions of years of formation and migration, crude oil is finally accessed through drilling. Long before dinosaurs roamed the planet, vast oceans and lakes were teeming with microscopic organisms like algae and zooplankton.
