Brief

Yield is how much liquid hydrocarbons you get per volume of the gas produced.

Measured at the surface.

Calculated from the Flash.

Math & Physics

 Yield = 10^6 \times \frac{x \times M_L \times \frac{1}{\rho_L} \times \frac{1}{5.615}}{y \times 379.5}\  \left [ \frac{bbl}{MMscf} \right ]

Nomenclature

 M_L = liquid molecular weight, lbm/lbmol
 \rho_L = liquid density, lbm/ft3
 x = molar fraction of the liquid phase, lbmol
 y = molar fraction of the vapor phase, lbmol
 Yield = yield, bbl/MMscf

Conversions

379.5 scf/lbmol at Psc=14.7 psia and Tsc 60°F [1]
