Canadian Oil and Gas Evaluation Handbook
The Canadian Oil and Gas Evaluation Handbook (COGEH) currently consists of three volumes that provide a set of standards and guidelines for the preparation of oil and gas reservoir 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.
