1. Scope
The proposed Practice describes methods for the determination of the gas content of coal by desorption, using samples obtained by surface drilling and from underground. It sets out guidelines for the equipment construction, sample preparation and testing procedure, and method of calculation.
Natural gas from unconventional sources, such as from coal beds (coal bed methane), has become a common target for exploration in recent years. Coal gas demand continues to grow and is expected to provide about 10 percent of US production in coming years. There are no commonly excepted guides, practices or standards available that describe current procedures used to determination the gas content of coal in North America. Gas content is the most important factor needed to determine the resource potential of a particular deposit. The proposed ASTM Practice will be used by government, industry, and research laboratories to establish procedures for equipment construction, sample preparation and testing procedure, and method of calculation.
