PO.DCA.PLE.D Function

Description:

Calculates instantaneous decline rate D(t) for Power Law Exponential (PLE) model, [1/T]. D(t) = D∞ + n×Di0×t^(n-1). Computed numerically.

Excel Function Syntax:

=PO.DCA.PLE.D(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].
