Method

Models: Arps exponential, hyperbolic, harmonic, Duong, and stretched exponential production decline are fit independently per well.

Selection: each well is ranked by corrected Akaike Information Criterion (AICc); the lowest AICc model is returned.

Forecast: EUR is integrated over the selected forecast horizon with a 5% annual terminal decline floor for Arps hyperbolic and harmonic fits.
