Coal Bed Methane (CBM) is generated by coal layers, there is a preceding process, which is the formation of coal (coalification). Coalification begins with the burial of organic material originating from plants. The burial, lasting hundreds of millions of years, results in increasing temperatures and pressures, causing physical and chemical changes to the organic material. Methane gas, the largest component of CBM, is formed. Two processes: biogenic and thermogenic. In the early stages of coalification, biogenic methane gas is produced as a byproduct of the activities of decomposing microorganisms (anaerobic bacteria), similar to what occurs in the decomposition of organic waste. Only about 5 to 20 percent is stored within coal. There are four mechanisms for gas storage in coal: absorption, adsorption, free gas, and gas dissolved in water. Among these four mechanisms, adsorption is the most significant, accounting for 98 percent of the stored CBM in a combined system of micropores (coal matrix) and cleats. Coal Bed Methane resources in Indonesia can be found across South Kalimantan, East Kalimantan, Sumatra, and Java.

“…Carbon naturally combines with other elements to form products of economic significance. Among these products, coal bed methane (CBM) has drawn tremendous attention in the energy market as a clean energy resource because it produces fewer greenhouse gases than other conventional sources [1]. Coal bed methane (CH 4 ) occurs naturally within coal beds and is usually trapped within the coal matrix due to adsorption.…”

“…The reasonably large amount of coal deposits in India gives leverage for CBM recovery. India currently possesses 2600 billion cubic meters (BCM) of total CBM reserves, and CBM has been produced commercially since 2007 [1,[9][10][11][12]. According to the Directorate General of Hydrocarbons [13], CBM resources in the Indian Coal Basin are identified as having an area of 26,000 km 2 and ~91.8 TCF (trillion cubic feet).…”

Biogeochemical Controls on Methane Generation: A Review on Indian Coal Resources

Coal bed methane (CBM) extraction has astounding effects on the global energy budget. Since the earliest discoveries of CBM, this natural gas form has witnessed ever-increasing demands from the core sectors of the economy. CBM is an unconventional source of energy occurring naturally within coal beds. The multiphase CBM generation during coal evolution commences with microbial diagenesis of the sedimentary organic matter during peatification, followed by early to mature thermogenic kerogen decomposition and post-coalification occurrences. Indeed, the origin of the CBM and, moreover, its economically valuable retention within coal seams is a function of various parameters. Several noticeable knowledge gaps include the controls of coal make-up and its physico-chemical position on the CBM generation and genetic link through fossil molecular and stable isotopic integration with the parent coal during its evolution. Therefore, this manuscript reviews the origin of CBM; the influences of coal properties and micropetrographic entities on CBM generation and storage; and its genetic molecular and stable isotope compositions in India and the world’s major coal reservoirs. Moreover, analyses of and outlooks on future development trends in the exploration, production, and application of coalbed methane are also addressed. Finally, as India has the fifth largest proven coal reserves, this brief review of the recent CBM discoveries and developments provides a plausible scope for microbially enhanced CBM production from these basins.

“…Ye analyzed the relationship among the structure (Pan et al, 2019), micro-pores (Liu X. F. et al, 2022), micro-cracks (Zhang et al, 2021a), and CBM content (Ma Y. K. et al, 2020;Lu et al, 2021), which is of great significance for the optimal selection of CBM production areas (Niu et al, 2019;Ye et al, 2019;Zhou et al, 2021). Sinha took a mine in India as an example to study the geological model of the CBM-enhanced recovery process (Sinha and Gupta, 2021). Fu analyzed the potential evaluation of CBM and developed sweet-spot prediction based on the developed geological conditions in the Yangjiapo block in the eastern Ordos Basin (Zou et al, 2018c).…”

Geological structures of Sima coal mine in Shanxi Province were analyzed to understand the control effect of the geological structures on the occurrence of coalbed methane (CBM) in coal seam #3 of Sima coal mine. The CBM contents in the districts #2 and #3 of Sima coal mine were tested, and the effects of buried depth, fault and collapse column on the distribution of coalbed methane content are studied. The research results showed that: 1) The average content of CBM has a linear relationship with buried depth and overburden thickness, but in the smallscale range of buried depth, the dispersion between CBM and buried depth is very large. 2) Faults and collapse columns significantly affect the content of local CBM nearby, but from the largescale range such as the whole mining area, the average value of CBM content at a certain buried depth will not be affected by faults and collapse columns. 3) In the hanging wall of F29 normal fault, it is roughly estimated that the average escape rate of CBM near the fault is 13.9%, while in the footwall of F29 normal fault, this value is 0.7%–1.1%. The results show that there is a significant difference in the influence of the fault on the CBM content in the hanging wall and footwall. 4) The control effect of collapse column on CBM occurrence is related to the development height of collapse column, the cementation degree of collapse column, groundwater runoff conditions and other factors. It can be divided into three categories: aggregation action, escape action (such as collapse column X8) and no obvious effect (such as collapse column DX7).
