Reservoir Rocks and Caprocks The effectiveness of a reservoir depends on the rock's porosity and permeability. Over time, these organic materials were buried under layers of sediment and rock, subjected to intense heat and pressure, which transformed them into the liquid hydrocarbons we extract today.
Migration Trapping Mechanisms That Trap Crude Oil in Reservoir Rocks
If temperatures rise beyond this range, the oil may further break down into natural gas. Crude oil is a fossil energy source formed from the remains of ancient marine microorganisms that lived millions of years ago.
The caprock, a dense and non-porous layer, plays a crucial role in preventing the oil from escaping, ensuring that the hydrocarbons remain trapped until they are drilled and produced. Extraction and Modern Recovery After millions of years of formation, crude oil is accessed through drilling.

These variations determine the oil's density, viscosity, sulfur content, and overall quality, influencing its value and refining process. Typically, temperatures between 60°C and 120°C are optimal for the conversion of organic material into liquid oil.
