hey all,

I am working on an old oil field for re-developement, so there is a huge lack of data and i we have to do a lot of correlation...

Ive got a question regarding Rs,Bo,Pb,viscosity calculation...

what is given is the Pb of the oil, oil viscosity at reservoir and stack tank oil condition, initial reservoir pressure, Temperature of the Reservoir and Bo at reservoir condition...
Up till now i dont have any information about my gas- nada.

Viscosity@65°C 3,5 - 4 cp
Viscosity@20°C 40 cp
Pb 48,7 bar
Density@20°C 0,65 g/ml
Bo @Res. Condition 1,057
Temp. 65°C
Pi 179 bar

with the given data i need to build my PVTO table (Rs, Pbub, FVF, Visc)
I dont have any idea how to correlate it (how to find out the different values at differen Pbub???)

Any advice or help is welcome !!

thank you in advance
