The IADC Lexicon is an oil and gas dictionary of upstream-related terms, which, unlike conventional glossaries, are official definitions drawn from legislation, regulation and regulatory guidance, standards (global, national and regional), IADC guidelines, and Well Control Institute. Terms often have multiple definitions from different sources.
This month’s featured term is:
