Posted: 18 Mar 2011 10:00 AM PDT Single Point Test: this test consists only of an extended flow period. An estimate of the degree of turbulent flow in the formation is required by this test. This estimate is often based on information provided by other wells in the same formation or calculated from reservoir and fluid properties. Similar Posts: |
Posted: 18 Mar 2011 03:53 AM PDT Modified Isochronal Test: similar to isochronal test which perfoms that each shut-in period between flow periods should be of the same duration as each flow period. It requires an extended flow period as well.Similar Posts:

Posted: 18 Mar 2011 03:42 AM PDT Isochronal Test: type of deliverability test which is conducted by producing a well at several flow rates for the same duration periods. The duration of period requires much less than the time required for stabilization. This test perfoms a long shut-in to allow well reach essentially static conditions between each flow period. Moreover, this test also requires an extended flow rate, long enough to acquire stable pressure. This isochronal test is not practical in low permeability tight reservoirs since it requres long time to reach pressure stabilization between flow periods.Similar Posts:

Posted: 18 Mar 2011 12:03 AM PDT Back Pressure Test: type of deliverability test which is conducted by flowing a well at different rates. Each production rate is maintained until pressure stabilization has been reached and the radius of investigation has reached the outer edge of the drainage area. This type of test is useful for high permeability reservoirs because the time to reach pressure stabilization for each rate is reasonable. Similar Posts: |
Posted: 17 Mar 2011 08:13 PM PDT Simplified Analysis: a method to calculate absolute open flow (AOF) or deliverability of well. This method using C & n to estimate the AOF. In most cases the simplified analysis is sufficient to determine the AOF and deliverability. If you have turbulance as dominant flow and the extrapolation to the AOG is large, you can use Laminar Inertial Turbulent (LIT) analysis which is more rigorous than simplified analysis. |
Posted: 17 Mar 2011 07:44 PM PDT Laminar Inertial Turbulent: a method to analyze absolute open flow (AOF) of well, other method is called simplified analysis using C & n method. LIT method is usually used in well test where the extrapolation to the AOF is large and turbulence is dominant and the well rate is high. This method is more accurate than simplified method.
