Oil extracted from an oil field is available as a mixture of oil, natural gas, and natural gas liquids that flow into a gas-oil separation unit. After the unit separates water and oil from the natural gas mixture, water is recycled or pumped into a disposal well. However, oil, natural gas, and natural gas liquids flow to the respective storage units. With the lowest CO2 emissions of any fossil fuel, natural gas is a flexible energy source that can displace carbon-intensive coal and play an essential role in the energy transition.
