[Opm] Calculating ROIP and RGIP

[Joakim Hove]

[ OK - this is slightly emberrassing; but I have reached the limit of my
understanding of the black-oil model. ]


When calculating the summary quantities ROIP (Region oil in place) and RGIP
(Region gas in place) we should sum up over the correct phase, and the
amount of oil/gas in the "other phase":

I.e. RGIP  ~ sum( SGAS + RS(?)) and ROIP = sum( (1 - sgas + swat) + RV)

But RS and RV are not in the "saturation space". So what gives?
