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).
