* TRES is the sub-string used for the tank (and leak) results. This is the data that can be viewed in the History Matching-Run Simulation dialog or the Production
Prediction-Run Prediction dialog.
There are three indices to be used with TRES:
The first index defines the stream, where:
- Index 0 is the production history stream - Index 1 is the history simulation stream - Index 2 is the production prediction stream Other indices will refer to any saved streams.
The second index defines the sheet within the stream:
For single tank cases there will only ever be one sheet which refers to the one and only tank, so always use 0. For multi-tank cases, the first sheet will always be the consolidated results for all tanks i.e. the sum of all tanks. The next N sheets contain results for each of the N tanks. The next M sheets contain results for each of the M leaks.
The third index defines the row in the sheet, where each row is for a different time.
**WRES is the sub-string used for the well results. This is the data that can be viewed in the Production Prediction-Well Results dialog.
There are three indices to be used with WRES:
The first index defines the well.
The second index defines the sheet within the stream.
For a well that has a single layer (i.e. connection to a tank) there will only ever be one sheet which refers to the one and only layer, so always use 0. For multi-layer well, the first sheet will be the results for the well. The next N sheets contain results for each of the N layers.
The third index defines the row in the sheet, where each row is for a different time.
5.6.7 Production Allocation
Most of the production allocation data is the same as the data for the material balance tool. Therefore the variable names are mostly the same as the material balance tool.
The additional variables used by the production allocation tool are listed below:
