Abstract: Production decline analysis is the analysis of the past trends of declining production performance, that is, rate versus time and rate versus cumulative production plots, for wells and reservoirs. In petroleum industry there are four methods to evaluate the reserves such as volumetric, material balance, numerical simulation and decline curve analysis. Decline curve analysis has been used to provide a best-fit equation for series of data point by least squares method. This method has been proved useful for decline curve analysis in order to estimate the initial decline rate (D), initial rate (qi) and the hyperbolic exponent (b), which can be used to plot the declining rate versus time after calculating the future rate at any desired time and calculating the reserves from certain time to an economic.
