Description
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.
Key trends below Pb: As pressure drops, gas comes out of solution — Rs decreases, Bo decreases (oil shrinks), and viscosity increases (oil gets thicker).
Workflow
- Inputs: Fluid properties (SG_gas, API, T) and initial solution GOR (Rsi)
- Step 1: Estimate bubble point pressure (Pb) from Standing correlation
- Step 2: Calculate dead oil viscosity at reservoir temperature (Beal)
- Step 3: Sweep pressure from Pb down — compute Rs, Bo, μo at each step
- Output: Pressure-dependent PVT property table for reservoir simulation input
