Get well constraints

[Theophile88]

Hi,
I would like to know how to access the well constraints (WCONPROD, WCONINJE) for wells at each time step.
Can it be done with ecl?
Thanks!

Hi,
Sorry for the delayed answer. No, I don't believe the simulators store the constraints of the wells in the summary files. One would have to get those from the DATA file instead. ecl does not parse the DATA file (to such an extent), perhaps though opm can help you out instead, that definitively parse the DATA file, I would try it!

Edit: I gave it a go to figure it out, but admittedly it was a bit difficult to find docs on it. ecl2df is slightly more user friendly in that regards (it uses opm to parse the data file, and provides a bit more convenience)

from ecl2df import wcon, EclFiles

eclfiles = EclFiles("MYDATADECK.DATA")
dframe = wcon.df(eclfiles)

And the Pandas dataframe you receive contains well constraint information

Hi,
Thanks a lot for your reply! It is exactly what I was looking for. I did a script myself, but this option looks more complete and reliable.
