Petroleum Reserves

Management and Information


In this course, participants learn to estimate petroleum reserves using SEC and SPE/WPC definitions, guidelines and latest interpretations. Instructors will present the main reservoir engineering and geoscience methods used to estimate reserves, and demonstrate how definitions affect such estimates. Case studies are used to illustrate different methods for estimating reserves, along with typical errors and how to avoid them. Participants will also learn supplemental techniques such as reservoir simulation and probabilistic methods for estimating reserves.

Topics Include:

  • The purpose of reserves
  • Reserves studies, reports, and definitions
  • Petroleum fluids
  • Resources vs. reserves
  • US Reserve Standards
  • Reserve classification and status
  • Typical problems identified by the SEC
  • International reserve standards
  • Methods for estimating reserves
  • Volumetric method, recovery factors, and reservoir simulation
  • Reserve audits, quality control, and SEC hot topics
  • The Sarbanes-Oxley Act

Why Attend?

The rules that govern the way the oil industry reports oil and gas reserves aim to protect investors and ensure energy supplies. If your job includes dealing with SEC and SPE/WPC guidelines, this course offers a quick way to refresh your understanding of the process and learn about the latest changes.

Who Should Attend

This course is designed for industry professionals involved in estimating or filing petroleum reserves under SEC or SPE/WPC guidelines, or any oil or gas professionals interested in gaining a better understanding of the process of estimating reserves.

Special Requirements

A basic knowledge of reserves definitions and estimation methods is desirable, but not required.
