The distinction between technical capacity and commercial capacity is where most confusion arises. A saline formation may have very large theoretical pore volume, a smaller volume that could physically accept CO2 given pressure constraints, a smaller volume still that a specific project could inject given its wells and its rate, and a smaller volume again that is supported by a contracted CO2 supply, a permit and a route to market. Published capacity figures frequently quote the first and are read as the last, which distorts investment and policy discussion alike.

Commerciality for storage is not the same test as for petroleum. A petroleum project is commercial when the resource can be produced and sold at a profit. A storage project has no product to sell in the conventional sense; its revenue comes from a fee for accepting CO2, from credits, or from a regulatory obligation being discharged, and its viability depends on a CO2 source existing, being captured, being transportable and being contracted. The subsurface may be entirely adequate while the project remains non-commercial for reasons wholly above ground.

Evidence requirements scale with category, and for storage the evidence is different in kind. Petroleum reserves are supported by production tests, well performance and analogue field behaviour. Storage capacity in the higher confidence categories requires injection testing, demonstrated injectivity, characterised containment and, increasingly, actual injection performance. Early projects are therefore classified conservatively, and the framework is explicit about what is required to move a quantity to a higher category.

Finally, the framework is becoming the basis for disclosure and for transactions. As storage becomes a traded service and storage sites become assets that are bought, sold and financed, classification under a recognised system becomes the language in which capacity is described. Understanding it is now part of working in the field rather than a specialist reporting function.

By the end of this training, participants will be able to:

• Describe the SRMS framework structure including maturity classes and uncertainty categories
• Distinguish storable quantities from theoretical and technical capacity
• Apply project maturity criteria and assess a project's classification
• Apply the commerciality test appropriate to storage projects
• Assign storable quantities to categories against their evidence requirements
• Apply deterministic and probabilistic estimation methods within the framework
• Calculate storage capacity using volumetric, dynamic and pressure-limited approaches
• Apply aggregation rules across projects and portfolios
• Compare SRMS classification with petroleum reserves frameworks and explain the differences
• Prepare storage capacity reports and supporting documentation for audit and third party review

The training works through the framework by applying it to storage projects at different stages of maturity, with participants classifying quantities, assessing commerciality and identifying the evidence required to move a quantity to a higher category. Capacity estimates are calculated by multiple methods and reconciled. Published capacity figures are examined against the framework to identify what they actually represent. Reporting formats and audit questions are practised on prepared cases.

Organisations sending participants to this training will:

• Report storage capacity on a recognised and comparable basis
• Avoid overstating capacity by conflating technical and commercial quantities
• Identify what evidence is required to mature capacity to a higher category
• Improve the credibility of capacity figures presented to regulators, partners and investors
• Prepare for third party audit and certification of storage resources
• Support storage transactions and financing with defensible classification

Participants will:

• Apply SRMS classification confidently to storage projects
• Distinguish the capacity categories and what each requires
• Estimate capacity by appropriate methods for each category
• Prepare capacity reports that will withstand review
• Translate between storage and petroleum resources frameworks
• Build a capability required as storage becomes a reported and traded asset

• Reservoir engineers working on CO2 storage projects
• Reserves and resources evaluation engineers extending into storage
• Geoscientists characterising storage sites
• Commercial and business development staff working on CCUS
• Regulatory, permitting and compliance personnel
• Auditors and technical reviewers assessing storage capacity claims
• Finance and investment staff evaluating storage assets

Upon successful completion of this training course, delegates will be awarded an official Certificate of Completion issued by the Petroleum Engineers Association (PEA), an ISO 9001:2015 certified training organization. The certificate carries 10 Credits and formally records the total learning hours completed.

Each certificate is signed by the Course Facilitator and the CEO of the Petroleum Engineers Association, and serves as verifiable proof of professional training that delegates can present to employers and professional bodies worldwide.
