natural gascarbon isotopethermochemical sulfate reductionmigrationTarim BasinThe origin of natural gases in central Tarim Basin is very complicated and there has been no definite conclusion in this aspect. Based on the results of systematic research on their composition and carbon isotopic characteristics,...
Timing and origin of natural gas accumulation in the Siljan impact structure, Sweden Henrik Drake, Nick M. W. Roberts, Christine Heim, Martin J. Whitehouse, Sandra Siljeström, Ellen Kooijman, Curt Broman, Magnus Ivarsson & Mats E. Åström Nature Communications volume 10, ...
Origin, migration and secondary processes of oil and natural gas in the western part of the Polish Outer Carpathians: geochemical and geological approach The origin, migration pathways, as well as the influence of secondary processes of oil and natural gas accumulated in lower Cretaceous to lower...
摘要: The isotope shows that gas in Hutubi gas field is coal- derived and sourced from Jurassic rock. Secondary cracking existed in Hutubi gas field. The filling history was determined according the gas generation kinectics.关键词: Hutubi gas field Gas Origin Carbon and hydrogen isotope Light...
GAS POTENTIAL OF BITUMEN IN THE SINIAN STRATA FROM THE MIDDLE SICHUAN PALEO-UPLIFT, SICHUAN BASIN, P. R. CHINA The Sichuan Basin is located in the middle of the China plate. It is well known by its very rich natural gas resources. Before 1990, commercial gas reservo... X Xiao,Y Huang...
In this paper, the origin of natural gas in the formations of the Changxing–Feixianguan within the Longgang gas field was studied in detail using geochemical methods. The gas discovered has a very high dryness coefficient, yet low ethane and other less heavy hydrocarbons content. Apart from a...

The chemical and stable isotopic compositions of natural gases from Jiannan Gas Field, Sichuan Basin, China, were investigated to elucidate the origin of the gas and to reconstruct the reservoir filling history. The natural gases in Jiannan Gas Field are dominated by CH4 with low amounts of non...
Studies have been made by several laboratories on the isotopic and chemical abundances of He, Ne, Ar, Kr, and Xe in natural gases from both gas wells and geothermal areas. This work has shown that the rare gases consist of a mixture of two distinct components--atmospheric and radiogenic. ...
