Source check
Each formula needs a credible textbook, society, glossary, technical article, or source-linked reference before it should be promoted as reviewed.
Formula review methodology
PetroCalcHub tracks source references, unit checks, default-result checks, and review status for petroleum engineering formulas. A calculator can be useful before it is fully reviewed, but the page should make that status visible.
Unit check
Field-unit constants and declared input/output units are checked against the cited formula and the calculator implementation.
Default-result check
Default values must produce finite results through the shared calculation engine before a formula is considered ready.
Review statuses
Reviewed
The formula, units, default result, and cited source have been checked for the current implementation.
Needs review
The record has a source trail but still needs independent formula, unit, or default-result verification.
Unreviewed
The formula should not be featured in priority SEO hubs until a source and calculation review is complete.
Corrections and improvements
If a formula, unit conversion, default example, or source citation looks wrong, report it with the equation name, source reference, expected correction, and any supporting calculation.
