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
Calculate oil compressibility at p = 10 MPa?
