IADC Lexicon Featured Term for January 2019

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.

This month’s Featured Term is:

“Normal Pressure” (API RP 59, Recommended Practice for Well Control Operations, Second Edition, May 2006) :

Formation pressure equal to the pressure exerted by a vertical column of water with salinity normal for the geographic area.
