Solution GOR -- Vasquez & Beggs

In this spreadsheet, just type in the required information and press the compute button. Scroll down for more info.

Pressure
psia
Gamma_g
Tr
deg F
Gamma_API
API
Rs
scf/STB
V&B's correlation.
Rs = C1*Gamma_g*p**C2*exp(C3*Gamma_API/(T+460))
Where
Rs = solution GOR, scf/STB, [20,2070]
p = pressure, psia [50,5250]
Gamma_g = gas gravity (air=1.0), [0.56,1.18]
Tr = reservoir temperature, F, [70,295] and
Gamma_API = stock-tank oil gravity, API [16,58].
C1, C2 and C3 are constants, depending on API.
