The intense heat and pressure broke down the complex organic molecules, stripping away oxygen and other elements, leaving behind the purest form of hydrocarbons. This process, known as diagenesis and catagenesis, essentially cooked the dead plankton.
How Heat and Pressure Transform Ancient Organic Matter into Oil Reservoirs
Why Organic Matter is the Key Ingredient For oil to form, the organic material must be rich in hydrocarbons, which are molecules composed primarily of hydrogen and carbon. The Transformation: Heat, Pressure, and Time Once the organic matter was buried under sediment, the transformation into oil began.
When the rock is penetrated, the pressure within the reservoir forces the oil to the surface. Migration and Trapping: Finding the Reservoir After the oil formed, it did not remain in the source rock.
How Heat and Pressure Transform Ancient Organic Matter into Oil Reservoirs
The Biological Origins: Life and Death in Ancient Seas The story of oil begins in the warm, shallow seas that covered vast portions of the Earth hundreds of millions of years ago. The primary contributors to oil formation were not large dinosaurs, as often depicted, but rather immense quantities of microscopic organisms.
