Geological Origins of Oil and Natural Gas
Oil and gas are formed from prehistoric organic matter, mainly marine microorganisms like algae and zooplankton, that settled in oxygen-poor environments and were buried under layers of sedimentary rock. Over millions of years, heat, pressure and bacterial action transformed this organic material into hydrocarbons.
These hydrocarbons serve as the raw materials for the entire energy industry, providing the foundational inputs for further processing and use. The process begins with the formation of kerogen which matures into crude oil and natural gas depending on temperature and depth.
These hydrocarbons, classified as fossil fuels, are a primary energy source for modern society. They migrate through porous reservoir rock and become trapped beneath impermeable cap rock layers, forming extractable reserves. Understanding this geological sequence is critical for upstream exploration helping geoscientists identify viable drilling zones and predict reservoir behavior.
Most source rocks are shale and the oil window typically lies between 2 to 4 kilometers deep where temperatures range from 60 to 120 degrees Celsius.
