1.0: Introduction

The precedent of the PRMS Guidelines for Application of the Petroleum Resources Management System (2011; hereafter referred to as “PRMS Guidelines”) to supplement the Petroleum Resources Management System (2007; hereafter referred to as “PRMS”) highlighted the importance of guidelines to the CO ₂ Storage Resources Management System (2017; hereafter referred to as “SRMS”). The SRMS, a project-based system, is independent of implementation and, therefore, does not provide advice. The SRMS guidelines include suggestions for the application of the SRMS with the intent of including details of the processes of quantification, categorization, and classification of storable quantities so that the subjective nature of subsurface assessments can be consistent between storage resource assessors. As more experience is gained in how commercial project frameworks will be developed, the SRMS and these guidelines will be updated.
