stock_tank_gas_sg
Calculate specific gravity of gas liberated from oil at atmospheric conditions for sales gas quality, flare calculations, emissions estimation, and safety assessments.
Instructions
Calculate stock tank gas specific gravity.
Computes the specific gravity of gas liberated at stock tank conditions. This is the gas that comes out of solution when oil reaches atmospheric pressure and temperature.
Stock tank gas properties are needed for:
Sales gas quality specifications
Flare gas calculations
VOC emissions estimation
Safety assessments
Returns dimensionless specific gravity (air = 1.0).
Args: request: Stock tank gas parameters including oil properties and separator conditions
Returns: Dictionary with stock tank gas SG value(s), units, and inputs
