PO.DCA.Arps.Prod

Description

Calculates cumulative production using Arps (1945) decline curve, [L3]. Units of volume [L3] and time [T] must be consistent. Use b=0 for exponential, 0<b<1 for hyperbolic, b=1 for harmonic.

Syntax

=PO.DCA.Arps.Prod(Qi, Di, b, time)

Parameters

Parameter	Description
Qi	Initial rate, [L3/T].
Di	Initial nominal decline rate, [1/T].
b	Hyperbolic exponent, [dimensionless].
time	Time, [T].
