The Oil & Gas Acronym Reference

Petroleum Acronyms is an independent reference glossary covering more than 15,000+ acronyms, abbreviations, and technical terms used throughout the oil and gas industry. The database spans the full lifecycle of petroleum operations — from exploration and drilling through production, processing, transportation, and decommissioning — and includes terminology from upstream, midstream, and downstream disciplines.

Whether you are a petroleum engineer decoding a technical report, a geoscientist reviewing well documentation, a student navigating industry literature for the first time, or a non-technical professional working alongside field teams, this glossary gives you fast, reliable definitions without requiring access to proprietary standards documents or company-internal reference guides.

Entries are sourced from published industry standards, regulatory filings, and technical documentation across multiple disciplines — including drilling engineering, reservoir management, HSE, production operations, facilities, logistics, commercial, and finance. The glossary is continuously updated as new terms are submitted and verified by the community.
