API (American Petroleum Institute)
Also known as: API
A U.S. trade association and standards-development organization for the oil and natural gas industry. API publishes technical standards, recommended practices, specifications, and certification programs used for equipment, drilling, production, refining, pipelines, measurement, safety, and environmental performance. In a crude-oil property context, “API” may instead refer to API gravity, a scale that compares a petroleum liquid’s density with water; a higher API gravity generally indicates a lighter liquid.
