This workflow is a guide for analyzing both drawdown / buildup and injection / falloff tests.
1. Depending on the type of data you have, start a Drawdown / Buildup, or Injection / Falloff project. See Starting a Project for details.
2. Import your pressure data.
3. Import your rate data. If you have multiple files containing rate data, such as cleanup flow and test production, import each file and then merge the rates together.
4. Synchronize the rates to the pressures.
5. Click the Production Editor tab. The Select Data to Analyze dialog box opens. Ensure that the imported pressure dataset is displayed in the Active Pressure drop-down list, and that the imported rate dataset is displayed in the Gas, Oil, or Water Rate drop-down lists; click OK. See Loading Data into the Production Editor for additional information.
6. Remove unnecessary data points (see Deleting Data at the Start or End of the Production Editor for details), such as pressure data before and after the test.
7. Specify shut-in points by entering a zero rate in the row of the data table with the first buildup (or falloff) pressure. Check the data chart to ensure that the rates go to zero immediately before the pressure buildup (or falloff) begins.
9. Filter the data in the Production Editor. We recommend filtering the data down to fewer than 5,000 points to speed up model calculations.
10. Click the Properties tab and enter the relevant fluid properties.
12. Conduct an analysis.
14. History match your data.
16. (Optional) If desired, perform an absolute open flow (AOF) analysis.
17. Create a report. See Designing a Report for additional information.
