There are few approaches to match the Arps decline to the historical data:
To ensure the smooth transition from historical data to the production forecasts in future time moments one may wish to constrain the model by firm matching the production at the last historical moment which leads to the following form of Arp's model:
Exponential Production Decline | Hyperbolic Production Decline | Harmonic Production Decline | |||
---|---|---|---|---|---|
