Tools & Guides
Reservoir Engineering Tools
Free calculators and guided workflows for common reservoir engineering problems. These are being built out gradually — check back, or get in touch if you need something applied to your own field data now.
Calculators
Quick, self-serve tools
Decline Curve Calculator
Coming soonFit exponential, hyperbolic, or harmonic Arps models to rate/time data and estimate EUR.
Unit Converter
Coming soonReservoir-specific unit conversions — bbl/stb, scf/m³, psi/bar/kPa, permeability, and more.
PVT Correlation Calculator
Coming soonEstimate Bo, Rs, viscosity, and compressibility from standard correlations when lab PVT isn't available.
Volumetric Quick-Screening Tool
Coming soonRough OOIP/OGIP range from basic reservoir parameters — for early-stage target screening.
Workflow Guides
Work through the method with me
These involve engineering judgment, not just a formula — they walk through the approach rather than giving an instant answer.
Rock Typing (FZI) Guide
Coming soonWork through flow zone indicator calculation and rock type clustering from porosity/permeability pairs.
Well Test / Horner Plot Analysis
Coming soonBuild a Horner plot from buildup data and estimate permeability, skin, and initial pressure.
Relative Permeability Curve Fitting
Coming soonFit Corey or LET models to lab Kr data for simulation input.
Material Balance Calculator (P/Z)
Coming soonP/Z vs. cumulative production method for OGIP estimation in volumetric gas reservoirs.
