McCain Oil Formation Volume Factor correlation in the PVT Software

B_o = \frac{\rho_{STO}+1.22117R_s\gamma_g}{\rho_{oR}}

Example source ^[2]

R_s

= 53.24 sm3/sm3

SG_o

= 0.85 or 35 API

SG_g

= 0.75

T

= 90C or 363K

P

= 10 MPa

Calculate oil density at p = 10 MPa?

\rho_o

= 749.645 kg/m3

The solution is available in the online PVT calculator software model at www.pengtools.com

= oil formation volume factor, rm³/sm³

R_s

= solution gas-oil ratio, sm³/sm³

SG_g

= gas specific gravity, dimensionless

\rho_{oR}

= oil density at reservoir conditions, kg/m³

\rho_{STO}

= stock tank oil density, kg/m³
