For example, the exponential decline curve tends to underestimate reserves and production rates; the harmonic decline curve has a trendency to overpredict the reservoir performance2. In some cases, production decline data do not follow any model but cross over the entire set of curves8.

Hyperbolic, Exponential & Harmonic Decline Curves ... There are 2 special cases of the hyperbolic decline curve: the Exponential curve and the Harmonic curve. If n = 0, the rate equation reduces to a one-parameter Exponential ... If n = 1, the rate equation reduces to the one-parameter Harmonic decline equation:

Harmonic decline is when b = 1. During both hyperbolic and harmonic behavior, the decline rate (D) decreases with time. Accordingly, the choice of b value ...

(2) Check whether harmonic decline applies by making a semi-log plot of flow rate q versus cumulative production Np . If the plot gives a straight line, then the slope = and the intercept on the y-axis = log qi.

The authors have observed from well histories as well as numerical simulation that forecasting based on either a linear p/z trend with cumulative production or an assumed exponential decline is conservative, while forecasting based on a harmonic decline trend is optimistic.
