A reservoir that took millions of years to accumulate might be drained in a century or less. When these organisms died, they settled on the ocean floor, becoming buried under layers of sediment.
How Ancient Organisms Formed Oil Reserves Over Millions of Years
Proved reserves—the amount of oil that is economically and technologically feasible to extract—will likely last for several decades. Crude oil is a fossil fuel created from the remains of ancient marine microorganisms, such as algae and zooplankton, that lived hundreds of millions of years ago.
When examining the energy landscape that powers modern civilization, few questions are as fundamental as whether oil is a renewable or nonrenewable resource. Solar and wind energy rely on ongoing natural processes—the sun shining and wind blowing—which are expected to continue for billions of years.
How Ancient Organisms Formed Oil Reserves
Because the supply is finite, markets are subject to volatility based on remaining reserves and geopolitical tensions. Over immense periods—typically 50 to 600 million years—heat and pressure transformed this organic matter into the hydrocarbons we extract today.
