IADC Lexicon Featured Term for September 2023

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:

Choke/Kill Manifold

An assembly of valves, chokes, gauges, and lines used to control the rate of flow and pressure from the well when the BOPs are closed.
