I have been comparing CO2 simulations at Sleipner using Eclipse and OPM. In order to get comparable results I had to convert the OPM injection rates to reservoir conditions (multiply with the Bg) manually. How does the wells in OPM treat volumes?

The compressible tpfa solver in opm-core (class CompressibleTpfa) is capable of dealing with well constraints given in either surface volumes or reservoir volumes. The incompressible solver is not (reservoir volume only), and the same applies to the impes solvers of opm-porsol (blackoil and co2).

There is at the moment some overlap between core and porsol. If you look at opm/porsol/blackoil/fluid for example, you will find much of the same functionality as in opm/core/props. The fluid property classes were refactored for use in opm-core and moved there, but the pre-existing simulators have never been updated to use opm-core fluid property classes (which is why nothing has been removed from opm/porsol/blackoil).

To some extent, the same holds for wells. The updated version of well treatment is in opm-core, but the older impes simulators in opm-porsol does not use it (yet).

Thanks for the explanation.
