WebMar 7, 2016 · Flow regimes on the diagnostic plot. A major application of the diagnostic plot is the potential that it provides in identifying the flow regimes that appear in a logical sequence during a buildup or flow test. For example, consider Fig. 7. At early times, the unit slope line on both derivative and pressure change, indicating wellbore storage. WebThe example flow regime maps shown in Figure 6.11 and Figure 6.12 illustrate two important points. The first point is how the flow regimes are incorporated into the flow correlations. The variables on the x-axis and y-axis are calculated, and that point on the map indicates the flow regime that is occurring in a well segment based on the investigator’s …
