CBM is formed during the process of coalification by the transformation of plant material into coal. ISO 4657 is an International Standard that discusses assessment specifications of coalbed methane resources.
ISO 4657 specifies the objectives, tasks, work processes, classification, report preparation, and acceptance of coalbed methane (CBM) resource evaluation.
ISO 4657 on assessment specification of CBM resources is useful for:
CBM is an unconventional form of natural gas found in coal deposits or coal seams. It is a primary clean energy source of natural gas. The development and utilization of CBM are of great social and economic benefit.
The objective of the evaluation provided under ISO 4657 is to understand the distribution of CBM and the basic geological characteristics of CBM reservoirs in the evaluation region, locate the CBM exploration targets, evaluate the total amount, quality, and certainty of CBM resources, lay a foundation for submitting a CBM reserves report, and provide a basis for prospective planning of CBM exploration and development.
ISO 4657 is useful for clean-burning fuel for domestic and industrial uses. Overall, ISO 4657 aids in the development and use of CBM, resulting in significant social, economic, and environmental benefits.
