Resources and Reserves estimation is an essential task in our industry for internal resources accounting, financial transactions, and regulatory reporting at the very least. To ensure consistency, transparency, and reliability for these estimations, The SPE Oil & Gas Reserves Committee ‘OGRC’ with sponsorship from AAPG WPC, SPEE, SEG, EAGE and SPWLA developed the Petroleum Resources Management System ‘PRMS’ which is currently recognized as an industry-wide standard for definition, classification, and estimation of hydrocarbon resources. In addition, the same consortium of societies has pioneered and published the Storage Resources Management System ‘SRMS’ as an industry guide for CO2 storage quantity and capacity assessment. So, with this background, what is the role of Petrophysics in hydrocarbon resources and reserves, and CO2 storage quantity and capacity assessment as per these industry guidelines? This presentation will cover • an overview of background, principles, and framework of the PRMS and SRMS. • the role of petrophysics in as per these guidelines in estimating hydrocarbon resources and reserves, and CO2 storage quantities and capacities. Who Should Attend? All practicing petrophysicists, log analysts, and reserves estimators.


Joshua Oletu is a Principal Advisor at Gaffney, Cline & Associates’ (GaffneyCline[1]) western hemisphere headquarters in Houston. He has some 30 years of experience in the international oil and gas arena and has carried out numerous field studies, reserve assessments, and asset evaluations.

Joshua began his career in 1988 as a Wellsite Petroleum Engineer with Shell Petroleum Development Company, Nigeria and had international postings to the Netherlands, and USA. In 2007, he joined GaffneyCline in the United States.

He has a B.Eng in Mechanical Engineering from University of Benin, Benin City, Nigeria and MBA, New York Institute of Technology (USA). Joshua is a member of SPE and the Society of Petrophysicists and Well Log Analysts (SPWLA).

He is currently the President of the SPWLA Hydrocarbon Resources Special Interest Group (HC – SIG)
