PetroCalc runs volumetrics, decline curves, PVT, full-cycle economics, risking, and Monte Carlo in one browser tab — with math benchmarked against PHDWin, ARIES, and Ryder Scott RyVOL.
Today that means jumping between PHDWin, ARIES, three spreadsheets, and a PVT correlation you half-remember. Spreadsheets don't have validated correlations or a real risking framework. PetroCalc puts the whole screening workflow in one place — and the numbers hold up.
No installs, no IT ticket, no $15K license.
OOIP / OGIP, NTG, saturation-pressure analysis, full PVT tables with separator correction.
Arps with transient plateau / BDF, EUR, and a clean rate-vs-time forecast.
Monthly cashflow, NPV, IRR, payout, WI/NRI, severance & ad-valorem tax, IDC — SPE mid-period discounting.
Five-factor chance of success — Pg, EMV, and a sensitivity tornado.
Probabilistic volumetrics with P90 / P50 / P10 and full distributions.
Save and compare prospects across devices. Export a polished PDF or PowerPoint in one click.
Every correlation is the published industry standard, validated against Ryder Scott RyVOL, PHDWin, and ARIES as ground truth — and locked down by an automated test suite so it stays that way.
One prospect evaluation saved pays for the year.
Every correlation is a published industry standard — Hall-Yarborough, Standing, Vazquez-Beggs, Beggs-Robinson, Wichert-Aziz — validated against Ryder Scott RyVOL, PHDWin, and ARIES, and locked down by 1,400+ automated tests. It's built for screening-grade decisions, not as a substitute for a stamped reserves report.
