The International Association of Drilling Contractors (IADC) is dedicated to enhancing the interests of the oil-and-gas and geothermal drilling and completion industry worldwide. Membership is open to any company involved in oil and gas exploration, drilling or production, well servicing, oilfield manufacturing or other rig-site services. IADC's contract-drilling members own most of the world's land and offshore drilling units and drill the vast majority of the wells that produce the planet's oil and gas. IADC's membership also includes oil-and-gas producers, and manufacturers and suppliers of oilfield equipment and services.
Founded in 1940, IADC's mission is to improve industry health, safety and environmental practices; advance drilling and completion technology; and champion responsible standards, practices, legislation and regulations that provide for safe, efficient and environmentally sound drilling operations worldwide. Through conferences, training seminars, print and electronic publications, and a comprehensive network of technical publications, IADC continually fosters education and communication within the upstream petroleum industry.
IADC holds Accredited Observer status at the International Maritime Organization and the International Seabed Federation, branches of the United Nations.
The Association is a leader in developing standards for industry training, notably its Well Control Accreditation Program (WellCAP)® and rig-floor orientation program, RIG PASS®. IADC is headquartered in Houston and is one of the city's largest trade and professional associations. IADC also has offices in Washington D.C., the Netherlands, Thailand and the United Arab Emirates, as well as chapters in the UK, Venezuela, Brazil, Australasia, South Central Asia, Southeast Asia, the Middle East and across the United States.
