Tools & Guides
Free calculators and guided workflows for common reservoir engineering problems. These are being built out gradually — check back, or get in touch to discuss a specific case.
Calculators
Fit exponential, hyperbolic, or harmonic Arps models to rate/time data and estimate EUR.
Reservoir-specific unit conversions — bbl/stb, scf/m³, psi/bar/kPa, permeability, and more.
Estimate Bo, Rs, viscosity, and compressibility from standard correlations when lab PVT isn't available.
Rough OOIP/OGIP range from basic reservoir parameters — for early-stage target screening.
Workflow Guides
These involve engineering judgment, not just a formula — they walk through the approach rather than giving an instant answer.
Work through flow zone indicator calculation and rock type clustering from porosity/permeability pairs.
Build a Horner plot from buildup data and estimate permeability, skin, and initial pressure.
Fit Corey or LET models to lab Kr data for simulation input.
P/Z vs. cumulative production method for OGIP estimation in volumetric gas reservoirs.
