The development of specifications of coalbed methane resources / reserves, that is suitable for our national conditions and compatible with international standards, can promote the reasonable utilization; prevent the disaster of gas of coal mine; and prevent atmospheric environment of coalbed methane resource, under the situation of the reform and opening-up policy. In order to adapt the needs of exploration, development and resources / reserves management of coalbed, Ministry of Land and Resources issued Specifications for Coalbed Methane Resources / Reserves (DZ/T 0216-2002) in the form of geological mineral industry standard of the People’s Republic of China on December 17, 2002. It will be put into effect on March 1, 2003. After more than 7 years of implementation, this specifications has played a role in promoting the development of coalbed methane; in the meanwhile, it also exposes some shortcomings. On January 29, 2008, the Consulting and Research Center of the Ministry of Land and Resources Entrust Department conducted a study, and revised the specifications to be this Standard. From the implementation date of this Standard, the previous standard shall be abolished simultaneously. SN/T 2034-2007 Specifications for coalbed methane resources / reserves 1  Scope  This Standard specifies the classification and grading standard, definitions, reserves estimation methods, reserves evaluation standard, and preparation requirements for reserves report of China's coalbed methane resources / reserves. This Standard is applicable to the ground-exploited-mine’s coalbed methane resources / reserves assessment and report preparation. It may be used as basis for the coalbed methane resources / reserves estimation review, the preparation of development program and medium-term and long-term planning in the coalbed methane resources / reserves management and mining economic activities. Regional survey and resources evaluation for coalbed methane resources, or resources / reserves estimation and report preparation of for exploitation and exploitation of coalbed methane by other means can be executed by reference. 2  Normative references  The articles contained in the following documents have formed this Standard when they are quoted herein. For the dated documents are quoted, all the modifications or revisions made thereafter shall be applicable to this Standard.

This Standard specifies that the required estimating resources / reserves mainly refers to adsorbed gas. 3.2 Coalbed methane resources The total amount of coalbed methane which is occurred in coalbed, according to the estimation by certain geological and exploration engineering basis; is recoverable in current time or future; and has the realistic economic significance and potential economic significance. According to with- and without- prospecting-well engineering control, it is divided into the known reserves and potential reserves to be discovered. 3.3 Coalbed methane reserves 3.3.1 Original coalbed methane in place Under the original state, the total coalbed methane which is occurred in the known coalbed with a clear estimation boundary; has realistic economic significance. According to exploration degree, it is divided into 3 levels - forecasted, controlled, and proved. 3.3.2 Recoverable reserves The recoverable part of the original coalbed methane in place. It refers to using the existing technologies and theoretical estimation or analogy to calculate the recoverable total coalbed methane, under the current laws and policies and market conditions. It is divided into “controlled” and “proved” levels, according to exploration degree. For recovery-rate parameter, it may be obtained by adopting the methods such as analogy and numerical simulation of the same domestic or foreign geological conditions. 3.3.3 Commercial recoverable reserve It is part of the recoverable reserves. It refers to using methods such as theoretical estimation or analogy to calculate the recoverable total coalbed methane, under the current economic and technical conditions. It can be divided into the “controlled” and the “proved” levels, SN/T 2034-2007 according to exploration degree. 3.3.4 Developed initial reserves The proved commercial recoverable reserves that is consumed by the corresponding cumulative production. Generally it may be obtained by using the cumulative production to be divided by recovery-rate. 3.3.5 Remainder proved initial reserves (referred as remainder reserves) The difference BETWEEN proved commercial recoverable reserves AND developed initial reserves is the remainder proved initial reserves. Remainder proved initial reserves are divided into “built capacity remainder commercial recoverable reserves” and “un-built capacity remainder commercial recoverable reserves”. Built capacity remainder commercial recoverable reserves refer to the remainder proved initial reserves that is occupied by under-built or built capacity. Un-built capacity remainder commercial recoverable reserves refer to the difference BETWEEEN the remainder proved initial reserves AND built capacity remainder commercial recoverable reserves. 3.3.6 Coalbed methane reserves abundance The coalbed methane reserves in the unit of coalbed containing-gas area. 3.4 Coalbed methane well 3.4.1 Prospecting well The engineering well which adopts drilling-well, supplemented by logging-well and coring analysis test method, to determine the parameters such as coalbed’s depth, thickness, struct... ......
