5.3.6 Recalculating Continuous mode data
To recalculate Continuous mode data, refer to Figure 5-5 and:
1. Select
Recalculate from the Well Performance Measurement menu.
2. Specify the archive record 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 archives, and can be viewed using the View
Archives option described in Section 5.3.5. The recalculation record is displayed with the
original timestamp and the term REC, as shown in Figure 5-5.
• 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 Continuous
mode measurement period.
• Only 96 snapshot records (24 hours of data) are stored. If the measurement period 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 measurement period.
• You may recalculate results for each archive record, and you may recalculate each archive
record more than once.
• Only one recalculation record can be saved. 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 another
recalculation.
• 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.
