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
= 90C or 363K
= 0.85 or 35 API
= 0.75
Calculate oil compressibility at p = 10 MPa?
Solution
= 0.002912 MPa-1 or 2.95E-4 atm
The solution is available in the online PVT calculator software model at www.pengtools.com
Nomenclature
- = oil compressibility, MPa-1
