B01.1 • Loading and interpreting a production WITHOUT pressures
When loading data in Topaze one must know whether the data is defined by instantaneous
values, or as steps. In the later case, the times in the file can be treated as the duration of the
steps, the time at the start, or the time at the end of the steps.
B01.2 • Loading a production
In this example, rates are defined by steps and duration.
Click on the Production option, the
dialog in Figure B01.6 is displayed.
The ASCII file option should be
already selected.
Open the file TopGS01.rat located
in the Examples sub-directory.
Click Next, the Data Format dialog
pops up, Figure B01.7 appears.
Fig. B01.6 • Define data source
The file complies with 'free format',
i.e. 2 decimal numbers per line and
Topaze identifies automatically the
time and rate fields.
Choose 'Steps: durations'.
In a more complex situation, one
could use the header buttons in
the grid, to define the various
fields in the file. Alternatively, the
definition could be based on
column range rather than fields
(column tab). Please refer to the
on-line help or software reference
for details.
The defaults are fine. Click Load. Fig. B01.7 • Data format
A production History plot is automatically created with the rate in yellow, and the cumulative
production in orange (all defaults can be changed in Settings – Plot Aspect). In the second
toolbar from the top, the 'Production' list now shows TopGS01, the rate gauge we have just
loaded.
The bottom part of the History plot is meant to display a pressure gauge and it will therefore
remain empty for the time being.
