PO.DCA.PLE.Prod Function
Description:
Calculates cumulative production using Power Law Exponential (PLE) rate decline model. Units of volume [L3] and time [T] must be consistent.
Excel Function Syntax:
=PO.DCA.PLE.Prod(Qi0, Di0, Dinf, n, time)
Parameters:
| Parameter | Description |
|---|---|
| Qi0 | Rate "intercept", [L3/T]. |
| Di0 | Power-law decline coefficient, [1/T^n]. |
| Dinf | Decline constant at "infinite time", [1/T]. D_inf <= Di_intercept |
| n | Time "exponent", [dimensionless]. |
| time | Time, [T]. |

Decline Model Comparison
Compare multiple decline curve models for the same well. Different models may be more appropriate depending on reservoir type and flow regime. Arps is standard for conventional, Duong for unconventional transient, and PLE for tight/shale.
