Rate vs Cumulative Production: This chart type is most commonly used by reservoir engineers. The curve provides a visual trajectory of the Estimated Ultimate Recoverable (EUR), but does not effectively communicate the time it takes to achieve a level of cumulative production. As an example, in 2017 global crude oil + condensate production (typically used to define oil-this does not include natural gas liquids, biofuels, or other hydrocarbon liquids) was about 30 billion barrels. Cumulative world oil production at the end of 2017 was approximately 1.36 trillion barrels (1,360 billion barrels). As the initial flat rate increases from the base case assumptions, the flat period gets shortened to yield the same cumulative production volume as the base case and the same EUR of 2.8 Bcf/1,000 feet, assuming no reservoir damage caused by flowing at higher rates. Obviously, the higher the production rate, the higher the NPV and IRR. If you have historic production data, you can use a plot of log water/oil ratio (WOR) vs linear cumulative oil production plot to forecast the future WOR as a function of cumulative oil production. There is some theoretical basis for this approach, based on relative permability effects and displacement of oil by water. Some oil and gas wells decline at a faster rate, called hyperbolic or double exponential decline. Still faster declines can occur, especially in fractured reservoirs, called harmonic decline.
