HyperbolicDeclineCumulative
Description:
Calculates cumulative production using Arps (1945) hyperbolic decline curve, [L3]. Units of volume [L3] and time [T] must be consistent.
Excel Function Syntax:

Parameters:
| Parameter | Description |
|---|---|
| Qi | Initial rate, [L3/T]. |
| Di | Initial decline rate, [1/T]. |
| b | Degree of the line curvature, [dimensionless]. |
| time | Time, [T]. |
