Oil & Gas PVT Correlation Calculator: Standing, Vasquez-Beggs, Lee-Gonzalez-Eakin & Z-Factor
Full PVT correlation suite: Rs, Bo, dead and live oil viscosity, gas Z-factor and Bg, inputs for engineering workflows without volumetric Monte Carlo.
TAGLINE
Full PVT correlation suite: Rs, Bo, dead and live oil viscosity, gas Z-factor, Bg and gas viscosity — inputs for engineering workflows without volumetric Monte Carlo.
WHO IT'S FOR
Reservoir and production engineers needing quick PVT property tables from API gravity, gas gravity, and temperature.
WHAT IT DOES
Generates oil PVT tables with Standing Pb and Bo, Vasquez-Beggs Rs and Bo (published coefficient sets with separator-gas correction), Beggs-Robinson dead and live oil viscosity, and gas Z-factor (Dranchuk-Abou-Kassem from Sutton pseudo-criticals, cross-checked against Hall-Yarborough), Bg and Lee-Gonzalez-Eakin gas viscosity vs pressure. Crossplot tabs compare the correlations with the sample lab data.
