... of the compartmentalized reservoirs likely to be encountered and produced. The modeling itself is done in two steps. The first step is to model the individual responses of the reservoir types and superpose the responses in various combinations until a rough match of actual production history is achieved. This best-match...

... by defining an effective time as the cumulative production divided by the current production rate. This method appears to work well when the rate divided by the bottom hole producing pressure, declines smoothly and monotonically in time. There are however, difficulties with wells whose production history...
