Reserves and Resources Estimation and Reporting

Reservoir Descriptions and Dynamics Production and Operations Management and Information


This course is presently designed to be presented in two days, with about one and a half-days of structured presentations and discussion, with a half day to address any specific issues or situations of concern to the participants. This particular course focuses on the SPE PRMS. SPE PRMS has become the most widely used resource classification system in the industry and is accepted by many stock exchanges as their reporting standard.


  • Providing an overview of international industry practices
  • Ensuring a thorough understanding of key definitions and guidelines and the relationship between Reserves and Resources
  • Discussing in detail the handling of uncertainty, including deterministic and probabilistic methodologies.

Course Agenda (pdf)

Why Attend?

This course will serve as a platform for putting together the various elements of ideas and concepts, approaches and technologies for current Reserves and Resources Estimation and reporting. Discussions will provide the participants with a basis for developing their own integrated workflow and solutions to estimate oil and gas Reserves and Resources and for planning cost effective field development.

Who Should Attend

Attendees should be technical or commercial staff, including managers, who are or will be responsible for Reserves and Resources estimation or who will be responsible for the reporting of Reserves and Resources to senior levels within the company or externally.


Engineers are responsible for enhancing their professional competence throughout their careers. Licensed, chartered, and/or certified engineers are sometimes required by government entities to provide proof of continued professional development and training. Training credits are defined as Continuing Education Units (CEUs) or Professional Development Hours (PDH).

Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course.
