Sector Profile

The Oil and Gas sector includes the oil and gas extraction industry as well as petroleum refining. The United States is the world's third-largest petroleum producer, with more than 500,000 producing wells and approximately 4,000 oil and natural gas platforms operating in U.S. waters. Together, oil and gas supply 65 percent of U.S. energy. The nation's 144 refineries process more than 17 million barrels of crude oil every day. Oil and gas production facilities include 16,000 establishments with a value of shipments of $134 billion.

Industries in the oil and gas extraction industry operate and/or develop oil and gas field properties. Such activities may include exploration for crude petroleum and natural gas; drilling, completing, and equipping wells; operating separators, emulsion breakers, desilting equipment, and field gathering lines for crude petroleum and natural gas; and all other activities in the preparation of oil and gas up to the point of shipment from the producing property. The petroleum refining industry comprises establishments primarily engaged in refining crude petroleum into refined petroleum. Petroleum refining involves one or more of the following activities: fractionation; straight distillation of crude oil; and cracking.

Trade Associations

American Petroleum Institute API is a national trade association representing all aspects of America's oil and natural gas industry. API's 400 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. They are producers, refiners, suppliers, pipeline operators and marine transporters, as well as service and supply companies that support all segments of the industry.

American Exploration and Production Council AXPC is a national trade association representing 24 of the largest independent natural gas and crude oil exploration and production companies in the U.S. AXPC members are "independent" in the sense that that they do not have petroleum refining or retail marketing operations and therefore are not "integrated." They are generally publicly traded corporations. The AXPC companies as a group produce more than 40 percent of the natural gas in the United States, and account for approximately one-fifth of the country's domestic oil production.

Independent Petroleum Association of America IPAA is a national trade association that has represented independent oil and natural gas producers for three-quarters of a century. Today, IPAA represents the thousands of independent oil and natural gas producers and service companies across the United States. Independent producers develop 90 percent of domestic oil and gas wells, produce 68 percent of domestic oil and produce 82 percent of domestic natural gas. IPAA also operates in close cooperation with 44 unaffiliated independent national, state and regional associations, which together represent thousands of royalty owners and the companies that provide services and supplies to the domestic industry.
