Stretched Exponential Functions
Stretched exponential decline with characteristic time and stretching exponent.
6 functions
PO.DCA.SEDM.Rate(Qi, tau, n, time)
Calculates production rate using Stretched Exponential decline model. Units of volume [L3] and time [T] must be consistent.
PO.DCA.SEDM.Prod(Qi, tau, n, time)
Calculates cumulative production using Stretched Exponential decline model. Units of volume [L3] and time [T] must be consistent.
PO.DCA.SEDM.Time(Qi, tau, n, Q_econ)
Time to reach an economic rate limit for Stretched Exponential decline, [T].
PO.DCA.SEDM.EUR(Qi, tau, n, Q_econ)
Estimated Ultimate Recovery (EUR) to an economic rate limit for Stretched Exponential decline, [L3].
PO.DCA.SEDM.Fit(times, rates)
Fit Stretched Exponential decline to rate-time data and return parameters as a column array [Qi, Tau, N].
PO.DCA.SEDM.WFit(times, rates, weights)
Weighted fit of Stretched Exponential decline to rate-time data and return parameters as a column array [Qi, Tau, N].
