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.
