Stretched exponential decline theory

One of the benefits of a stretched exponential decline is that for positive n, t, qi, the model gives a finite value of EUR, even if no abandonment constraints are used in time or rate.

The Stretched Exponential Production Decline Model
Defining the differential equation of the model
q = Rate expression as a function of time
Q = Cumulative production as a function of time
EUR = EUR in terms of model parameters
