About Petroleum Acronyms

What Is This Site?

Petroleum Acronyms is a searchable glossary of more than 16,000 acronyms, abbreviations, and technical terms used throughout the oil and gas industry. The database spans upstream, midstream, and downstream operations, covering disciplines from drilling engineering and reservoir analysis to HSE, finance, and logistics.

The site is designed for petroleum engineers, geoscientists, operators, support staff, students, and anyone who works with or alongside the industry and needs a quick, reliable definition.

How It Works

Every search query is run against our full database of active entries, ranked by relevance. Exact acronym matches appear first, followed by partial matches and related terms. If you mistype a term, our QWERTY-similarity engine suggests the most likely alternatives based on keyboard proximity.

You can also browse the glossary alphabetically or explore by category.

Who Maintains It?

Petroleum Acronyms is an independently operated reference site. The database is built and maintained by a small team with backgrounds in petroleum engineering and technical publishing. Entries are sourced from industry standards, regulatory filings, company technical documentation, and community submissions — all reviewed before publication.
