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:
Closure of the underwater safety valve and possibly other valves depending on the control system design. NOTE Such commands can originate manually, automatically or as part of an ESD.
