Global events from Baghdad to Beijing and from The Hague to Houston over the decade past have ignited worldwide interest in oil and gas reserves. This renewed, expanded attention has clearly illustrated that the term “reserves” is widely misunderstood and abused – sometimes by financial analysts,, professional evaluators, politicians and/or organizations that should know better. Moreover, everyone seems to be an expert in the emerging “hydrocarbons from shale” discussion – ranging from the good, the bad and the ugly.

This presentation clarifies what the term “oil and gas reserves and resources means in several contexts. Various parties and stakeholders – for example regulators, financiers and producers – have differing needs for reserves information. However, whatever the need, all reserves estimates must be based on a sound understanding of the prevailing definitions and the value of adequate high-quality data. Trained, ethical and independent reserves evaluators must interpret and present these estimates. The term “independent” should apply to internal reserves staff as well as third-party reserves evaluators.

This presentation will describe ongoing efforts by the sponsors of the Petroleum Resources Management System (PRMS) issued in 2007 to engage evaluators worldwide to begin to explore evolutionary modifications to the PRMS embracing geological appraisal and technological advances since 2007. Included also will be a listing of many countries and stock exchanges adopting all or part of the PRMS for their regulatory reporting and governance.
