Reservoir Engineering Skill
Use pyResToolbox or pyrestoolbox-mcp for engineering correlations whenever possible. Avoid hand-rolling PVT, VLP, material balance, relative permeability, or DCA formulas unless the exercise explicitly asks for implementation.
Common Tool Families
- Oil PVT: bubble point, solution GOR, oil FVF, density, compressibility, viscosity.
- Gas PVT: pseudocritical properties, Z-factor, Bg, density, viscosity, compressibility, pseudopressure.
- DCA: Arps exponential/harmonic/hyperbolic, Duong, EUR, forecast, uptime handling.
- Material balance: gas P/Z, oil Havlena-Odeh, aquifer support, drive indices.
- Nodal/IPR/VLP: inflow curves, outflow curves, operating point, VFP tables.
- Simtools: SWOF/SGOF/SGWFN, PVTO/PVDO/PVDG/PVTW, AQUTAB, Rachford-Rice flash.
- Layer: Lorenz coefficient and permeability distributions.
- Brine/CO2: brine properties and CO2-brine mutual solubility.
Parameter Pitfalls
- Oil tools use
sg_g for gas gravity.
- Gas tools use
sg for gas gravity.
- Inflow tools use
psd, not pwf.
- Gas Z-factor uses
method; many other gas property tools use zmethod.
- Oil bubble point methods include
STAN, VALMC, and VELAR.
- Gas Z-factor methods include
DAK, HY, WYW, and BUR.
- Relative permeability table types include
SWOF, SGOF, and SGWFN.
Output Standard
Every answer should include:
- Inputs and units.
- Correlation or method used.
- Result table or scalar result.
- Engineering sanity check.
- Any applicability limits or assumptions.
