Our best fit will loop over these values, create the curve using the parameters, and test the fit to the known data. The default range for B-values are 0-2 and default range for initial decline is 3-90 (it is a percentage decline).Decline curve analysis (DCA) is a graphical procedure used for analyzing declining production rates and forecasting future performance of oil and gas wells. Oil and gas production rates decline as a function of time; loss of reservoir pressure, or changing relative volumes of the produced fluids, are usually the cause.Decline curve analysis (DCA) is an analytical process dating back to the 1940s widely used to estimate gas and oil reserves and expected ultimate recovery (EUR) of gas initially in-place (GIIP) in subsurface reservoirs. Empirical relationships and/or type curves are fitted to historical production data, the latter taking field conditions into ...
