“…(Mohr and Evans 2011). China possesses rich natural gas resources, and Chinese authorities have estimated that the TRR (technically recoverable resource) and URR (ultimately recoverable resources) of natural gas are 6.1 trillion cubic meters (tcm) and 37 tcm, respectively (Hou et al 2015;Zou et al 2015). Although China is rich in gas resources, the domestic natural gas industry in China developed slowly during its industrialized period.…”

China's energy consumption experienced rapid growth over the past three decades, raising great concerns for the future adjustment of China's energy consumption structure. This paper first presents the historical evidence on China's energy consumption by the fuel types and sectors. Then, by establishing a bottom-up accounting framework and using long-range energy alternatives planning energy modeling tool, the future of China's energy consumption structure under three scenarios is forecast. According to the estimates, China's total energy consumption will increase from 3014 million tonnes oil equivalent (Mtoe) in 2015 to 4470 Mtoe in 2040 under the current policies scenario, 4040 Mtoe in 2040 under the moderate policies scenario and 3320 Mtoe in 2040 under the strong policies scenario, respectively, lower than those of the IEA's estimations. In addition, the clean fuels (gas, nuclear and renewables) could be an effective alternative to the conventional fossil fuels (coal and oil) and offer much more potential. Furthermore, the industry sector has much strong reduction potentials than the other sectors. Finally, this paper suggests that the Chinese government should incorporate consideration of adjustment of the energy consumption structure into existing energy policies and measures in the future.

“…In the 21st century, sustainable human development is closely related to the supply of energy [1]. Coalbed methane (CBM) is an unconventional natural gas occurring in coal reservoirs [2]. Coal is a porous medium with heterogeneity, where many natural fractures, pores, and defects are randomly distributed [3].…”

Dynamic Evolution and Quantitative Characterization of Fractures in Coal at the Eastern Edge of Ordos Basin under Axial Loading

et al. 2023

Understanding the evolution of pore-fracture networks in coal during loading is of paramount importance for coalbed methane exploration. To shed light on these dynamic changes, this study undertook uniaxial compression experiments on coal samples collected from the eastern edge of the Ordos Basin, complemented by μ-CT scanning to obtain a 3D visualization of the crack network model. The compression process was divided into three stages, namely, micro-crack compaction, linear elasticity, and peak failure. An increase in stress resulted in greater concentration and unevenness in fractal dimensions, illustrating the propagation of initial cleats and micro-cracks in the dominant crack direction and the ensuing process of crack merging. These results provide valuable insights into the internal structure and behavior of coal under stress, informing more efficient strategies for coalbed methane extraction.

“…Recently, there has been an increase in the desire to recover hydrocarbons from formations with extremely low porosity (˂15%) and low permeability (˂0.1 mD), like coalbed methane reservoirs, methane hydrate, tight reservoirs, and shales (Yekeen et al, 2018). For these reservoirs to produce, horizontal drilling and multi-stage hydraulic fracturing techniques must be used to create artificial fractures that allow the flow of the gas to the wellbore (Hou et al, 2015). Water-based fracturing fluids have been in use for decades; however, the costs associated with formation damage, excessive water use, and environmental degradation have limited their field applications.…”
