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.

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.
