Different from the conventional, unconventional natural gas accumulations have obvious particularity in reservoir forming conditions, enrichment mechanism, distribution modes, prediction method and exploration technology. Analyzing the reservoir…
Natural gas currently represents close to a third of U.S. primary energy consumption and has often been described as a bridge fuel in the context of the ongoing energy transition. As coal plants are retired and the share of variable renewable…
Eocene and Lower Oligocene rocks are potential source rocks for crude oil accumulations in the Hungarian Palaeogene Basin. To enhance the understanding of the hydrocarbon system, this study (i) assesses the petroleum potential of Palaeogene…
The effects of crude oil on the microstructure and spontaneous combustion characteristics of coal were assessed, using raw coal sample and coal samples containing 5%, 10% and 15% oil. The pore structures, oxygen adsorption capacity, surface…
Hydrogen is a clean fuel that can potentially revolutionize the energy supply chain and decarbonize fuel consumption. However, a key hurdle that needs to be overcome before a full-scale hydrogen economy can be established is hydrogen storage which is…
Geomechanical evaluation of CO2 underground disposal is complex and can be even more challenging in coal reservoirs due to natural fractures and combined effects of multi-component transport. The objective of the research work presented in this paper…
We conducted simulation experiments on supercritical carbon dioxide (ScCO2)-H2O-rock interactions for caprock samples obtained from the Qinshui Basin, China, to explore the influence of carbon dioxide (CO2) injection on the sealing capability of deep…
The Baode block on the eastern margin of the Ordos Basin is a key area for the development of low-rank coalbed methane (CBM) in China. In order to find out the genesis of CBM and its storage and seepage space in Baode block, the isotopic testing of…
Hypothesis: Hydrogen geo-storage is considered as an option for large scale hydrogen storage in a full-scale hydrogen economy. Among different types of subsurface formations, coal seams look to be one of the best suitable options as coal's micro/nano…
A comparative study on organic geochemistry and kinetics was performed on two representative coal measure mudstone and coal samples of the Eocene Pinghu Formation in the Xihu Sag, East China Sea Shelf Basin, China. Gas chromatographymass spectrometry…
Carbon isotope composition (13C) has been used as a standard geochemical tool to explore the genetic and post-genetic information of natural gas systems. However, little attention has been paid to the influence of the diffusion loss on the real 13C…
The Ordos Basin is abundant in natural gas resources, and the Shanxi Formation with the transitional facies is considered as a potential stratum for shale gas reservoir. However, the origin and geochemical characteristics of the Shanxi Formation…
