Guest Speaker(s): William Walton & David Stevens (Molyneux Advisors)

William Walton Geoscientist, Project Leader and Resource Assurer with over 37 years of global assignments with BP and Shell covering field appraisal, development and production roles on conventional and unconventional assets. Over the last 12 years, William gained in-depth experience in Reserves and Resource assurance, together with opportunity evaluation and hydrocarbon maturation planning, primarily for Shell’s worldwide Integrated Gas assets. William is based in The Netherlands and is currently the Principal Reserves / Resource Consultant for Molyneux Advisors. He is a member of the SPE and SPEE (Society of Petroleum Evaluation Engineers). David Stevens David has nearly 40 years of global experience much of it gained in many Shell Group companies while holding Geoscientist, Chief Geologist, Petroleum Engineering Manager positions and more recently as a Senior Resource Assurance consultant. His expertise covered significant LNG assets in Australia, Malaysia and Qatar, together with Heavy Oil and Tight Gas in Oman. Currently David is based in Scotland and serves as Chief Production Geoscientist at Molyneux Advisors. He is a member of the SPE, SPEE and PESGB.

Accounting for CO2: Using the SPE-SRMS for Classification of CO2 Storage Resources

Presented by William Walton and David Stevens (Molyneux Advisors)


According to the IEA’s 2019 report (Exploring Clean Energy Pathways – The Role of CO2 Storage), CO2 utilisation and storage will be an important part of the portfolio of technologies and measures needed to achieve climate and energy goals. The carbon capture and storage market was estimated to be valued at US $2.6 billion in 2020 increasing to an estimated value of US $5.3 billion by 2026.

In 2007, the Society of Petroleum Engineers (SPE) published the first edition of the Petroleum Resource Management System (PRMS) covering classification and reporting of Petroleum Resources. This has since become the global standard in that field. In 2017, the SPE published the CO2 Storage Resource Management System (SRMS) based upon the PRMS, recognising the need to create a consistent set of definitions and a classification system for these resources.

While the required skillsets to characterise the subsurface for CO2 storage are the same e.g. geology, petrophysics, reservoir engineering and production technology, the “product” itself generates revenue in a fundamentally different way. After an introduction on key aspects of the SRMS, this will be followed by a discussion on differences arising from injection and storage of CO2 compared to recovery and sale of methane.
