PO.DCA.ModHyp.Time Function

Description:

Time to reach an economic rate limit for modified hyperbolic decline, [T]. Returns the time when the production rate falls to the specified economic limit.

Excel Function Syntax:

=PO.DCA.ModHyp.Time(Qi, Di, Dlim, b, Q_econ)

Parameters:

Parameter	Description
Qi	Initial rate, [L3/T].
Di	Initial nominal decline rate, [1/T].
Dlim	Decline rate limit when switch to exponential decline occurs, [1/T]. Dlim <= Di.
b	Hyperbolic exponent, [dimensionless].
Q_econ	Economic rate limit, [L3/T].
