2 The gas flow equation can be rewritten by taking the log of the equation: From this equation it is evident that a plot of the log of the flow rate against the log of the bottom hole pressure differences squared, will yield a straight line of reciprocal slope "n" as shown at right. The intersection of the straight line with the square of the shut-in bottom-hole pressure yields the theoretical flow from the reservoir (AOF) if the sand face pressure were reduced to zero. For a given well, the terms "C" and "n" may often be considered as constants. However, for wells with low permeability, "C" will decrease with increasing flow time. It will then be necessary to use the Isochronal or Modified Isochronal deliverability tests described below. The value of "n" will normally fall between.5 and 1.0. Values outside this range are not considered valid. A value of "n" equal to 1 indicates steady state viscous flow and a value of.5 indicates steady state turbulent flow. Once the value "n" has been determined for a given well, subsequent tests may use the "one-point" method. This technique assumes that the slope of the deliverability curve does not change with time. The "one-point" test requires the well-head pressures at one stabilized flow rate and after a stabilized shut-in. The well-head pressures are converted to bottom-hole pressures and the AOF is calculated from the equation:

3 To find the "deliverability" of the well against any line pressure, the equation is modified by substituting surface pressures for bottom-hole pressures: The "deliverability" is calculated after substituting the flow rate (Qwf) of the well with its corresponding well-head pressure (WHPwf), and a recent shut-in well-head pressure (WHPsi). The deliverability can then be calculated for any line pressure (Pline). Deliverability Test Procedures The "deliverability" test requires that the well be produced at several different rates, usually four. As a general rule, the rates should be high enough to create drawdowns of 5, 10, 15, and 20%, of the shut-in well-head pressure. The rates must also be sufficiently high to continuously unload produced fluids. The flow rate and the flowing well-head temperature should be accurately recorded at the end of each flow period. The flow periods must be of sufficient duration to achieve stabilized flow which is defined as pressure changes of less than 0.1% of the shut-in well-head pressure over 15 minutes. The figure at right is a diagram of the conventional deliverability test. The flowing well-head pressures (Pwfi) at the end of each flow rate(q1-q4) are converted to bottom-hole pressures and squared. The squared pressures are then subtracted from the square of the shut-in bottom-hole pressure (Psi). These differences are plotted against the flow rates on a log-log scale as shown in the previous graph.

4 When it is difficult or impractical to achieve stabilized flow because of low reservoir permeability, the Isochronal or Modified Isochronal multipoint test isused. In the Isochronal test, care is taken that the flow periods are of equal duration. At the end of each flow period, the well head pressure is allowed to return to the initial shut-in pressure (Psi). The last flow in the sequence is of extended duration in order to achieve stabilized flow. A diagram of the isochronal test is shown at right. Four sets of flow rate/whp values should be taken during each flow period. For the sake of clarity, the four data sets are only shown for flow period Q2. After converting the well-head pressures to BHP values, the plot shown below and to the right is constructed.

5 The slope of each line should be similar. The flowing well-head pressure at the end of the extended flow period is converted to bottom-hole pressure and used to locate the Stable Flow point on the previous plot. A line of the same slope is drawn through the Stable Flow point to obtain the AOF. To further shorten the test period for low permeability wells, the Modified Isochronal test is used. This test differs from the Isochronal test in that the flow periods and shut-in periods are of equal duration. The well is not allowed to build back to its pretest shut in pressure. The next plot shows the Modified Isochronal deliverability test. When plotting the data, care should be taken that the build-up pressure before each flow rate is used when calculating (Psi2 - Pwf2) for each flow. The plot is constructed and the AOF determined in the same manner as described for the Isochronal deliverability plot Halliburton. All Rights Reserved
