The IADC Lexicon (IADCLexicon.org) is a compendium of upstream-related terms, which, unlike conventional glossaries, are official definitions drawn from legislation, regulation and regulatory guidance, standards (global, national and regional), and IADC guidelines. Terms often have multiple definitions from different sources.
