Vasquez and Beggs Oil Compressibility correlation
Vasquez and Beggs is an empirical correlation for the oil compressibility published in 1980[1].
Math & Physics
Example. Calculation of the oil compressibility
Example source [3]
Input data
= 53.24 sm3/sm3 at P = 10 MPa
= 0.85 or 35 API
= 0.75
= 749 kg/m3 at P = 10 MPa
Calculate oil formation oil factor at p = 10 MPa?
Solution
= 1.199 rm3/sm3
The solution is available in the online PVT calculator software model at www.pengtools.com
Application range
Nomenclature
- = oil formation volume factor, rm3/sm3
- = solution gas-oil ratio, sm3/sm3
- = gas specific gravity, dimensionless
- = oil specific gravity, dimensionless
- = oil density at reservoir conditions, kg/m3
= stock tank oil density, kg/m3
