What does IADC stand for?

• A. International Association of Drilling Contractors
• B. International Association of Drilling Companies
• C. Institute for American Drilling Compliance
• D. International Agency for Drilling Cooperation

Answer: (A)

IADC stands for International Association of Drilling Contractors. This is the recognized industry group for drilling contractors and related service companies, and its name directly maps to the acronym: International (I), Association (A), Drilling (D), Contractors (C). The other options swap or modify words—Companies, Institute, or Agency—so they don’t reflect the actual organization or the common acronym used in the industry. You’ll see IADC referenced in safety standards, training programs, and industry guidelines, underscoring its role as a standards and advocacy body for drilling operations.
