5.2.5 Recalculating well test data
You can recalculate well test data for any stored well test. You can perform the recalculation during a
well test or between well tests. To recalculate well test data:
1. Refer to Figure 5-2 and select
Recalculate Well Test.
2. Navigate to the well test you want to recalculate.
3. Select
Recalc Parameters and set recalculation values as desired. See Table 5-9. You can set
one, several, or all of the recalculation values. If you do not assign a new value, the original
value is used during recalculation. When you have finished setting recalculation values, press
EXIT.
4. Select
Perform Recalculation. When recalculation is complete, the following message is
displayed:
Data Recalculation is complete.
Press OK to view and save the
recalculation results for this well.
Press OK to continue.
5. To view the results of the recalculation, select
View Recalc Data. When you are finished,
press
EXIT.
6. At this point, you can save or discard the results of the recalculation.
• To save the results of the recalculation, select
Save Recalc Data, then press EXIT. A
recalculation record will be written to the list of well tests for this well, and can be viewed
using the View Well Test menu shown in Figure 5-2. The recalculation record is displayed
with the original timestamp and the term REC.
• To discard the results of the recalculation, press
EXIT.
Note the following:
• Recalculation is based on the snapshot records written every 15 minutes during the well test.
• Only 96 snapshot records (24 hours of data) are stored. If the well test runs more than 24
hours, older snapshots are overwritten. Accordingly, the recalculation procedure is applied
only to data from the last 24 hours of the well test.
• You may recalculate results for each well test, and you may recalculate each well test more
than once.
• Only one recalculation record can be saved per well. If you perform a second recalculation and
save the results, the existing recalculation record will be overwritten. Be sure to record or
download (via Modbus) the existing recalculation record, if required, before performing the
next recalculation for the current well.
• TMR carry-over totals are not recalculated. If carry-over totals were added to the original oil
and water totals, the TMR carry-over data is not included in the recalculated totals.
