Problem:
When I load a CHEARS.hist file containing entities other than wells into Tecplot RS, Tecplot RS thinks these entities are wells, and does not allow us to do the comparisons we need to do, whereas older versions of Tecplot RS did allow us to make these comparisons.
How can I make these same comparisons in Tecplot RS?
Solution:
The CHEARS.hist file format is only intended to support wells. This is also true for the Tecplot RS Generic ASCII file format, since neither of these formats has a Category flag to indicate the type of entity.
To best make your comparisons in Tecplot RS, load your CHEARS.hist file into Excel and convert it to CHEARS CSV format. The conversion involves the following steps:
- Since Tecplot RS requires Date or Time in the first column, make sure this column appears first. If you use Date, be sure to use four digits, not two, for the year.
- Change the WELLNAME column label to just NAME.
- Add a Category column that describes the type of entity that the file contains.
- After editing the file, write it out as a CSV file. In order for Tecplot RS to identify the file, the name of this file must have the form: _prd.csv Tecplot RS uses the _prd addition at the end of the file name to identify this type of file.
After completing these steps, you can load your converted file in Tecplot RS by choosing “Load XY Data” from the Project menu, choosing Individual Files as the file type, and clicking the Browse button. In the Open Files dialog, set the File Type (in the lower right corner) to CHEARS CSV, and then browse to and choose your _prd.csv file.
