oil_sg_from_jacoby
Calculate oil specific gravity using molecular weight and aromaticity factor for petroleum fraction characterization in reservoir engineering applications.
Instructions
Calculate oil specific gravity from molecular weight and Jacoby aromaticity.
HYDROCARBON CHARACTERIZATION TOOL - Estimates specific gravity for undefined petroleum fractions using molecular weight and aromaticity.
Jacoby Aromaticity Factor (JA):
0.0 = Pure paraffinic (alkanes)
0.5 = Mixed (typical crude oils)
1.0 = Pure aromatic
Applications:
Plus fraction (C7+) characterization
Undefined heavy end lumping
EOS fluid modeling
Pseudo-component generation
Returns specific gravity (dimensionless, water=1).
Args: request: Molecular weight and Jacoby aromaticity factor
Returns: Dictionary with specific gravity, method, and inputs
