This complex process relies on specific geological conditions where buried sediments, algae, and plankton accumulate over millions of years. Modern drilling utilizes rotary rigs that can create a borehole miles deep.

Heat and Pressure Transformation At depths of several thousand feet, the temperature and pressure begin to rise significantly. Migration and Trapping Once formed, the oil is not static; it is mobile and seeks paths through porous rock layers.
Heavier molecules remain at the bottom, while lighter fractions vaporize and condense at various heights. It continues this upward journey until it encounters an impermeable cap rock, which acts as a barrier and traps the hydrocarbons in reservoirs.

Heat and pressure gradually convert this organic material into the hydrocarbon molecules that form the basis of petroleum. Heavier residues may undergo further processing, such as cracking, to convert them into more valuable lighter fuels.
