Oil and gas reserves classification
Proven reserves (also called measured reserves, 1P, and reserves) is a measure of fossil fuel energy reserves, such as oil reserves, natural gas reserves, and coal reserves. It is defined as the "[q]uantity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well established or known reservoirs with the existing equipment and under the existing operating conditions." Conventional Gas is a natural gas occurring in a normal porous and per- meable reservoir rock, either in the gaseous phase or dissolved in crude oil, and which technically can be produced by normal production practices Glossary of Reserves/Resources Terminology - 2005. Estimated Oil and Gas Reserves Classification of Resources and Reserves The BOEM resource classification framework is shown in Figure 2. Definitions for each resource class are presented in Appendix A. At the point in time a discovery is made, the identified accumulation of The revised definition for developed reserves applies to developed reserves of all categories, including proved, probable and possible reserves. In addition, the revised definition of developed oil and gas reserves no longer expressly requires a production response from the improved recovery technique to classify such reserves as developed. FASB Accounting Standards Codification (ASC) 932 requires disclosure of a standardized measure of discounted future cash flows relating to proved oil and gas reserves quantities for public companies. This is sometimes referred to as the standardized measure of oil and gas, or SMOG. Reserves are the volumes of oil and gas that the licensees have decided to recover, and are classified as resource class (RC) 1 to 3. Contingent resources have been proven, but no decision has been made regarding their production. Proved oil and gas reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the data the estimate is made.
The definitions used are in accordance with the SEC Rule 4–10 (a) of Proved reserves shown are net of any quantities of crude oil or natural gas that are

The revised definition for developed reserves applies to developed reserves of all categories, including proved, probable and possible reserves. In addition, the revised definition of developed oil and gas reserves no longer expressly requires a production response from the improved recovery technique to classify such reserves as developed. FASB Accounting Standards Codification (ASC) 932 requires disclosure of a standardized measure of discounted future cash flows relating to proved oil and gas reserves quantities for public companies. This is sometimes referred to as the standardized measure of oil and gas, or SMOG. Reserves are the volumes of oil and gas that the licensees have decided to recover, and are classified as resource class (RC) 1 to 3. Contingent resources have been proven, but no decision has been made regarding their production. Proved oil and gas reserves are the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the data the estimate is made. The vertical (classification) axis represents the project maturity. The life cycle of any oil or gas field starts with exploration. Geologists seek areas where oil and gas may exist and, on the basis of seismic and other data, may eventually drill an exploration well to see if any oil or gas can be found. For oil and gas companies, oil reserves are considered a depleting asset, in that the more reserves they extract, the less product they will have available to sell in the future. Reserves are The goal of the new oil and gas disclosure rules is to help investors evaluate the value of oil and gas companies by providing investors with a more meaningful and comprehensive picture of a company's oil and gas reserves.
Almost all applications of oil and gas reserve estimates require, in thefinal analysis, an economic evaluation that considers the predicted productioncapacity and
Reserves refer to oil / gas in a reservoir that has been confirmed to exist and is economically recoverable with current technology. Resources refer to oil/gas in a reservoir that is believed to exist but part or all of this volume has not been demonstrated to be productive or commercially recoverable. Resources is a collective term for all recoverable volumes of petroleum, and reserves are a particular type of resources. Historic production means all the oil and gas that has been produced, sold and delivered. Reserves are the volumes of oil and gas that the licensees have decided to recover, and are classified as resource class (RC) 1 to 3. In 1999, the SPE Oil and Gas Reserves Committee, in conjunction with WPC, undertook the development of a resource classification system that would include the 1997 reserves definitions. This effort was joined by the American Association of Petroleum Geologists (AAPG) later that year The SEC Final Rule—Modernization of Oil and Gas Reporting. For publicly traded U.S. E&P companies, oil and gas reserves reported in the notes to their annual reports filed with the SEC are determined by the “SEC Final Rule”. On December 31, 2008, the SEC issued a final rule revising disclosure requirements relating to oil and gas reserves.
