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 makes the difference between calculation checks and published engineering guidance 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.
Two levels of review
Calculation record reviewed
The formula definition, declared symbols and units, default result, and available source trail have passed the record-level checks used by the calculator library.
In-depth guidance published
The calculator also has separately written usage context, assumptions, limitations, common error checks, a reproducible example, and citation notes specific to that relationship.
Guidance in preparation
The working calculator and record metadata remain accessible, but the site does not present generic boilerplate as a substitute for equation-specific engineering interpretation.
Editorial responsibility and evidence
What review metadata means
Review labels record checks performed on the current PetroCalcHub implementation. They are an audit trail, not a claim that a calculator is certified, approved for a specific operation, or a substitute for a licensed professional.
How evidence is prioritized
Original papers, standards, textbooks, universities, professional societies, and authoritative technical glossaries are preferred. Secondary summaries may support discovery but should not override a primary equation or its stated limits.
Formula records are also checked by the shared parser and calculation engine for valid symbols, declared inputs and outputs, finite default results, and expected unit metadata. Automated checks catch structural errors but cannot establish field applicability; the cited source and engineering context still control.
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.
