Chapter 1: Introduction

The Guidelines for Application of the PRMS(or Application Guidelines, AG), as the name suggests, is the companion document to the Petroleum Resources Management System (PRMS), with the intended purpose of providing the PRMS user with a more detailed understanding of the principles involved therein for consistent practice in petroleum reserves and resources evaluation. Industry feedback through professional conferences, workshops, and public comment since the 2007 publication of the PRMS reinforced the need to issue further clarification and amplification of the PRMS and its guidelines. Consequently, to address these concerns, the original AG document was published in November 2011 (Guidelines for Application of the Petroleum Resources Management System 2011).
