How many years does an oil well produce?

The production life of an oil well can vary significantly depending on factors such as the type of reservoir, extraction techniques, and the oil field's geology. On average, an oil well may produce economically for about 20 to 30 years, but some wells can continue to yield oil for several decades while others may deplete in just a few years. Enhanced recovery methods can extend the productive life of a well beyond its initial output phase.
