Investopedia explains 'Decline Curve'

Most decline curves are based on exponential, hyperbolic or harmonic Arps equations, but tend to have shortcomings such as underestimating reserves, underestimating production rates, or overestimating reservoir performance. The Arps equations were developed in the mid-1900s but are still used today despite their limitations.
