IADC Lexicon Featured Term for May 2024

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:

  3. analyses planned to be carried out;
  4. operations planned to be carried out in the event of a possible removal;
