American Petroleum Institute
The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Their over 400 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. Their members are producers, refiners, suppliers, pipeline operators and marine transporters, as well as service and supply companies that support all segments of the industry. For more than 75 years, API has led the development of petroleum and petrochemical equipment and operating standards. In addition to its standards, API organizes seminars, workshops, conferences and symposia on public policy issues.
