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.
