Bubble Point Correlation Comparison

Compare bubble point pressure correlations from different sources and regions. Each correlation was developed for specific oil types and geographic regions, showing significant variation in predictions.

Bubble Point Estimation

Estimate bubble point pressure using different correlations. Compare Standing and Vasquez-Beggs methods side by side.

Complete Oil PVT Table

Complete oil PVT property table from undersaturated through saturated conditions. Includes bubble point, solution GOR, oil FVF, oil compressibility, and oil viscosity across the full pressure range.

Gas PVT Properties

Complete gas PVT property table including Z-factor, gas formation volume factor (Bg), gas compressibility (Cg), gas viscosity, and gas density across pressure range.

Gas Z-Factor Comparison

Compare gas compressibility factor (Z) calculations using different correlations. Shows DAK (Dranchuk-Abou-Kassem) and Brill-Beggs methods side by side.

Oil PVT Table - Standing

Complete PVT properties table using the Standing correlation. Calculates oil formation volume factor (Bo) and solution gas-oil ratio (Rs) for a range of pressures. **Usage:** Insert at desired location, modify input values in the Inputs section.

Oil Viscosity Correlation Comparison

Compare oil viscosity calculations showing the progression from dead oil through saturated conditions. Dead oil viscosity depends only on temperature and API gravity, while saturated oil viscosity also depends on solution GOR.

Oil Viscosity Table

Calculate oil viscosity using Egbogah (dead oil) and Beggs-Robinson (saturated) correlations.

PVT Fluid Properties Report

Generate a complete PVT fluid property report below the bubble point using Standing (Rs, Bo, Pb) and Beggs-Robinson (viscosity) correlations. The pressure sweep table shows how solution GOR, oil FVF, and oil viscosity change during reservoir depletion.

PVT Sensitivity to Oil Gravity

Compare PVT fluid properties across three oil gravities (25, 35, 45 °API) to quantify how API uncertainty affects bubble point, solution GOR, FVF, and viscosity. Heavy oils (low API) have lower Pb, less dissolved gas, and higher viscosity — light oils are the opposite.

Sour Gas PVT Properties

Calculate gas PVT properties for sour gas (containing H2S and CO2) using Wichert-Aziz pseudo-critical corrections. Compare sweet vs sour pseudo-critical properties and show how acid gas content affects Z-factor, Bg, density, and viscosity across a pressure range.

Water/Brine PVT Properties

Water/brine PVT property table using McCain correlations. Includes water FVF, gas solubility in water, water compressibility, and water viscosity.
