Abstract
Activities in the petroleum industry range from exploration, to oil and gas recovery or production, refining, distribution, and marketing. The nomenclature used has been derived from the disciplines of geology, petroleum engineering, and chemistry. This, combined with the complex nature of oil and many refined products, makes for a terminology that is often not systematic and has many poorly defined terms. An outline of the more widely used terms from exploration, production, and refining is included.
