API is governed by a Board of Directors, which chooses API's officers. The board carries out API's mission by designating segment committees, resource committees, and strategic committees. API members participate in any committees where they have assets and interests.

Segment Committees

API has patterned our organization to reflect America’s oil and natural gas industry and ensure every member has a voice.  Our members are producers, refiners, suppliers, pipeline operators and marine transporters.  They come from the largest oil companies to the smallest independents.

The Upstream Committee is open to companies producing oil or natural gas in the United States  (vertically integrated companies may be members of more than one API segment).

  • Focuses on upstream regulatory policy, legislative issues, and industry technical standards and recommended practices.
  • Emphasizes efforts to ensure that operations are conducted in a safe, efficient and environmentally responsible manner.

The Market Development Committee is open to companies producing oil or natural gas in the United States (vertically integrated companies may be members of more than one API segment).

  • Focuses on identifying policy opportunities and impediments to sustaining and growing demand for U.S. natural gas resources in targeted markets, advocating for legislative and regulatory policy and market designs that leverage the full value of natural gas.
  • Educates potential customers and decision makers on the abundance, reliability, affordability and environmental advantages of natural gas.

The Midstream Committee is open to companies gathering, processing, storing and transporting oil and natural gas in the United States (vertically integrated companies may be members of more than one API segment).

  • Develops policy positions for gathering, processing, storing and transportation and oversees the review of related federal, state, and local laws and regulations.
  • Identifies opportunities for technical studies and research to address issues related to development of U.S. infrastructure, use of equipment, development of operational procedures, and safety, health and environmental performance.
The Downstream Committee is open to companies that refine and market petroleum products in the United States (vertically integrated companies may be members of more than one API segment).

  • Provides guidance on the impact of legislative and regulatory proposals on downstream operations and provides scientific, economic, environmental, and risk analysis information on associated issues.
  • Develops standards, practices and positions that allow industry to provide products to consumers in the most safe, efficient and environmentally responsible way.

The General Membership Committee addresses the needs of non-oil company members such as service companies, drilling contractors, and other suppliers to the oil and natural gas industry.  Members can provide services to any industry segment, including upstream, downstream, marine or pipeline.

  • Works closely with all other industry segments to promote the shared interests of the industry.
  • Focuses on both domestic and international issues, particularly international trade issues, since many members in this segment supply products and services worldwide.

Resource Committees

The Committee on Communications oversees API’s outreach to the media and other external audiences to ensure they have the facts and information to develop informed perspectives on energy and industry issues.  This includes media relations, external communications, materials and publications development, Internet-based communications, community engagement and other educational outreach.

The Committee on Economics and Statistics oversees API's Policy and Statistics Departments.  Committee members provide guidance to API staff in policy analysis and statistical preparation. The committee vets fundamental policy positions and provides guidance to other API departments.

The Committee on Federal Relations implements API policies and programs on industry issues before Congress and the executive branch, and coordinates the government relations efforts of API and its member companies.  The committee is composed of the heads of member company offices in Washington, DC, responsible for federal government relations.

The Committee on Finance focuses on internal and external issues related to auditing, accounting, insurance and risk management.  It formulates industry responses to regulatory and legislative initiatives and to developments in industry finance areas.  The committee, composed of oil industry chief financial officers, sponsors API's Finance and Accounting Program.

The Committee on Health, Environment and Safety is responsible for identifying major health, environment and safety issues that could impact the industry and oversees those programs within API.  The committee also promotes sharing best practices and improving industry health, environmental and safety performance.

The Committee on Information Management and Technology oversees API’s interests in information technology; electronic business and telecommunications systems and management; cyber security; data privacy; and industry-level projects for evolving information systems.  This committee sponsors API's Information Technology Program.

The Committee on Law ensures API’s legal affairs are handled properly and efficiently.  The committee is responsible for reviewing and approving any litigation with which API becomes involved and works closely with other committees to ensure consistency of legal positions on industry issues.  The committee is composed of member companies’ general counsels.

The Committee on State Relations establishes industry policy for and ensures the proper management of state legislative and regulatory issues in the 33 states where API staffs state petroleum councils.  The committee coordinates with other API committees on policies and priorities at the state level.

The Global Industry Services Committee has jurisdiction over all non-dues programs, such as revenue-generating and cost recovery programs and special solicitations.  The committee provides financial oversight, works with API segment committees, and ensures that new opportunities meet API policy.

The Committee on Taxation formulates API tax policy and provides tax advice to the API president and board.  The committee determines the priority tax issues, both legislative and regulatory, and sets the overall agenda for the various tax subcommittees and the API Tax Department.  The committee is composed of senior taxation professionals at member companies.

Service and supply companies are an integral part of the oil and natural gas industry. In the United States, there are more than 10,000 companies identified as providing oil and natural gas services and supplies to the industry. Many of these are local companies that provide oil and gas services to operations in their area, while others are global manufacturers selling products for oil and gas operations around the world. They include:

Manufacturers of Equipment

Manufacturers of equipment are used in all aspects of the oil and natural gas industry. This includes some of the most technologically advanced equipment used in the search for oil and gas. This equipment allows the industry to operate in an environmentally safe way. These include manufacturers of equipment used in refineries as well as in oil and natural gas exploration and production.

Drilling Contractors

Drilling Contractors supply both the drilling rigs and the crews that search for oil and natural gas both onshore and offshore. Economists often measure the health of the industry based on the number of drilling rigs that are operating both on land and in the waters off the Outer Continental Shelf in the ocean. These drilling rigs undertake the initial search for oil and gas, and when their work is completed, they move on to the next site.

Service companies

Service companies assist oil and gas producers in maintaining the facilities that keep oil and natural gas production flowing.

Engineering companies

Engineering companies design and support the sophisticated oil and natural gas operations, including those operations that improve the refining capacity of existing refineries or companies that design complex systems for oil and natural gas exploration and production.

Inspection companies

Inspection companies provide qualified inspectors in all areas of the industry, including aboveground storage tank inspectors and pipeline inspectors.
