 Our Mission

The API Committee on Petroleum Measurement provides leadership in developing and maintaining cost effective, state of the art, hydrocarbon measurement standards and programs based on sound technical principles consistent with current measurement technology, recognized business accounting and engineering practices, and industry consensus. This is accomplished through the committee's and API’s leadership role in the national and international standardization community in the development, publication, promotion, and revision of petroleum measurement standards, through its subcommittee structure, and through elimination of duplicative efforts. The committee is supported by API's Standards and Training Group, whose mission is to meet the needs of API and the oil and natural gas industry by producing internationally-acceptable petroleum standards and training programs on a self-supporting basis.
