Canadian Oil and Gas Evaluation Handbook | Order Now »
The Canadian Oil and Gas Evaluation Handbook (COGEH) currently consists of three volumes (volume 3 is missing 2 chapters at this time) that provide a set of standards and guidelines for the preparation of oil and gas reservoirs evaluation in Canada. The Handbooks have been co-authored by the Society of Petroleum Evaluation Engineers (Calgary Chapter) and the Petroleum Society of Canada.
The Second Edition of Volume 1: Reserves Definitions and Evaluation Practices and Procedures (published September 2007) includes a discussion of evaluator qualifications, business procedures, definitions of resources and reserves with general guidelines, evaluation procedures, time values of money and profitability indicators, uncertainty, contents of evaluation reports, auditing oil and gas reserves information and financial analysis and benchmarking practices.
Volume 2: Detailed Guidelines for Estimation and Classification of Oil and Gas Resources and Reserves (published in November 2005) includes guidelines and examples of recommended procedures for estimating oil and gas resources and reserves for a variety of situations. The intent of Volume 2 is to provide guidance to experienced evaluators on a wide array of reserves estimation scenarios requiring specific considerations or evaluation methodologies. The guidance will also form a basis for estimating and classifying resources and reserves in more complex situations. The guidelines for estimation and classification of resources other than reserves (ROTR) was completed and added in July, 2014.
Volume 3: CBM Reserves and Resources/International Properties/Bitumen and SAGD Reserves Resources (published in September 2007) includes the evaluation of Coal Bed Methane (CBM) consistent with the definitions provided in COGEH Volumes 1 and 2, the reporting of reserves for international properties and detailed guidelines for the evaluation of bitumen and steam-assisted gravity drainage (SAGD) reserves and resources. The CBM portion addresses only the estimation of the gas volumes existing in, and recoverable from, coal. The section on international properties highlights the differences between evaluating reserves in North America and in various international jurisdictions. The section on bitumen and SAGD reserves and resources was published in April 2014.

Monograph Number 1 - Second Edition
The Second Edition, released in May 2004, includes the new reserves definitions themselves, as well as new sections on naturally fractured reservoirs and the application of geostatistics. Substantial revisions were made in sections involving horizontal wells, decline analysis, and risk and uncertainty. This 408-page hard bound volume replaces the First Edition, which has sold over 3000 copies since its release in 1994.
The estimation, classification, and reporting of oil and gas reserves and related substances has always been a vital part of the oil and gas industry. Yet, in spite of the obvious importance for consistent methods of reserves determination and terminology, no "standardized definitions" have ever been universally accepted across the industry.
The Second Edition makes an important contribution in leading the way toward setting that standard. Through the efforts of over forty authors, several co-ordinators, and numerous reviewers, the Petroleum Society Monograph Number 1, Determination of Oil and Gas Reserves, has been compiled to address the need for guidelines for the determination and classification of oil and gas reserves.
Along with a section on the definitions and guidelines for the classification of oil and gas reserves, prepared by the Standing Committee on Reserves Definitions of the Petroleum Society of Canada, the Monograph covers all aspects of reserves determination, reviewing methodologies associated with calculating hydrocarbons in place, recovery factors, and production forecasting. As well, the Monograph provides a focus on other influencing factors such as economics, markets, regulations, and risk.
The group of individuals involved in the formulation of this publication represents all segments of the industry, including government and regulatory agencies, financial institutions, oil and gas producers, service companies, and consulting firms. Therefore, this Monograph will be useful to a wide audience.
