PO.DCA.Arps.EUR Function
Description:
Estimated Ultimate Recovery (EUR) to an economic rate limit for Arps decline, [L3]. Returns cumulative production up to the time the rate reaches the economic limit.
Excel Function Syntax:
=PO.DCA.Arps.EUR(Qi, Di, b, Q_econ)
Parameters:
| Parameter | Description |
|---|---|
| Qi | Initial rate, [L3/T]. |
| Di | Initial nominal decline rate, [1/T]. |
| b | Hyperbolic exponent, [dimensionless]. |
| Q_econ | Economic rate limit, [L3/T]. |

EUR Calculator
Calculate Estimated Ultimate Recovery (EUR) for different economic limits and decline parameters. Essential for reserves estimation and economic analysis.
EUR Sensitivity Analysis
Sensitivity analysis of Estimated Ultimate Recovery (EUR) to Arps decline parameters. Understanding parameter uncertainty impact on EUR is critical for reserves estimation and economic analysis.
Modified Hyperbolic Decline
Modified Hyperbolic decline model that transitions from hyperbolic to exponential decline at a specified terminal decline rate. This addresses the unrealistic EUR predictions from pure hyperbolic decline with high b-factors.
