Manoel,
There is a manual for OPM Flow located here
https://opm-project.org/?page_id=955.
OPM Flow attempts to use the same keywords as the commercial simulator,
but naturally it does not have all the features as it's commercial
competitor so far, but it is getting there. For the aquifer you could
use grid cells with large pore volumes but you need to scale these
geometrically away from the reservoir cells otherwise you will have
large pore volumes from the aquifer blocks flushing through the "small"
reservoir cells. Another approach is use horizontal wells to simulate
the aquifer. None of these are ideal, but the former would be similar to
the commercial simulator's numerical aquifer.
The trend today is not to use analytical or even numerical aquifers but
to actually include the aquifer in the model. Analytical aquifers were
included in numerical models in order to provide a link between material
balance models and numerical models. Engineers would perform the overall
pressure matching using material balance and then incorporate the
analytical model into the numerical model.
I too was under the impression that LRAT was supported on the WCONHIST
keyword. However, the Norne model users RESV option so you can use this
instead of LRAT. And once you have a pressure match covert over to ORAT
control. I personally don't like using LRAT as it gives a false
impression on the quality of the match, and secondly, we have a highly
level of confidence in the oil volumes through the ticket sales.
Non-sellable fluids get little attention in the field.

Dear All,
I agree. I am trying to perform a history match, missing 2 things:
- Analytical Aquifers;
- WCONHIST keyword with 'LRAT' target.
This project is fantastic! I teach reservoir simulation here in Rio and
OPM-flow will be an alternative to run models on my course.
Best Regards,
Manoel

Hello!
I'm Claus. In the past few years, I have been researching meta-heuristics
for Reservoir History Matching using a (very crude)
python wrapper for Eclipse made by myself.
Today I found about the OPM project, and it would be FANTASTIC if I could
replace Eclipse with OPM on my workflow (or at least do the initial
development of the optimizers on OPM, and then the final testing on Eclipse
using opm-ecl).
However, after successfully running the tests and tutorials, I am having
difficulties running our models on OPM. For example, our simplest model
fails to run with the error:
"Keyword AQUFET not recognized"
(And indeed, the keyword is not in the OPM manual)
So I was wondering if there is some sort of manual, tutorial or guidelines
for making ECL models compatible with OPM Flow. I looked around the
documentation, project page, and the last year or so of the mailing list
but could not find anything.
Thank you very much!

Hi, Manoel,
Glad to know your interest in using OPM-flow in your reservoir simulation
course.
We do not have the support for Analytical Aquifers yet.
I believe the WCONHIST keywords with `LRAT` target should be supported. But if
you saw some problems related to this, would you like to provide a small model
for us to reproduce your problem? We would like to fix it whenever time permits.
Best,
Kai
