Research Methodology.
PetroEyes explains oil and gas markets with public data, reputable third-party sources, and clearly labelled editorial judgment. This page describes how we collect, check, and present information so readers can understand the limits of each chart or article.
1. Primary Source Aggregation
PetroEyes starts with primary and reputable sources wherever possible. We prefer official datasets and public company disclosures for prices, inventories, rig counts, policy claims, production figures, and financial metrics.
Governmental Sources
- U.S. Energy Information Administration (EIA)
- Baker Hughes (Rig Count Data)
- Saudi Ministry of Energy
- National Bureau of Statistics (China)
Intergovernmental Orgs
- OPEC Secretariat
- International Energy Agency (IEA)
- Joint Organisations Data Initiative (JODI)
2. Normalization & Reconciliation
Raw data is rarely uniform. PetroEyes normalizes units, dates, and reporting windows before comparing one source with another.
Unit Conversion Standards
Universal conversion of cubic meters, tonnes, and barrels using temperature-corrected API gravity standards.
Temporal Alignment
Mapping asynchronous reporting cycles (e.g., weekly EIA vs. monthly IEA) onto a unified temporal grid for comparative analysis.
3. Editorial Review Layer
Data needs context. After data is normalized, PetroEyes editors review whether the change is seasonal, source-driven, policy-driven, infrastructure-related, or still too uncertain to treat as a durable signal.
Reported Data vs. Interpretation
Articles should make it clear when a sentence is based on reported data, when it is a scenario, and when it is the author's interpretation. Forecasts are educational, not trading advice.
4. Regulatory & Emissions Context
Energy valuation and commodity analysis often depend on policy and emissions assumptions. PetroEyes treats those assumptions as context, not certainty:
Carbon Tax Tiering
Carbon pricing and emissions rules are discussed with jurisdiction, timing, and policy-source context where available.
Methane Intensity
Methane and flaring claims should be tied to company disclosures, regulator reports, or reputable emissions datasets.
ARO Liability Front-Loading
Asset retirement obligations are treated as real balance-sheet context when discussing mature upstream producers.
5. Quality Assurance Protocol
PetroEyes uses a practical review process before publishing or refreshing data-driven pages:
- 01Variance Check
Large moves are checked against source notes, seasonal patterns, and prior revisions before being described as a trend.
- 02Source Review
Editors check whether a claim should point to EIA, Baker Hughes, IEA, OPEC, company filings, or another reputable source.
- 03Plain-Language Edit
Final edits remove hype, mark uncertainty, and keep market commentary separate from personal financial advice.
Advisory Note
Energy markets are volatile, and official data can be revised. PetroEyes updates public data files as source updates are processed, but readers should verify time-sensitive figures before relying on them.
