The Cambrian is the most poorly dated period of the past 541 million years. Here, the authors present a new astronomical time scale, allowing for a first assessment, in numerical time, of the evolution of major biotic and abiotic changes that charact

The Steptoean Positive Carbon Isotope Excursion Event (SPICE) represents one of the largest carbon cycle perturbations in the Cambrian, which coincided with climatic changes and dramatic extinction of shallow-shelf faunas. This carbon perturbation ha

Profound environmental and biological changes took place during the Cambrian, yet, compared to other Phanerozoic intervals, the Cambrian time framework remains poorly constrained, which severely hinders a detailed understanding of the timing and prog

The Dongpu Depression, especially the northern part, is an important natural gas-rich area in the Bohai Bay Basin, China. The gases found in Es3M, Es3L and Es4 are mainly distributed in the western part of Qianliyuan, in Weicheng, and in the middle o

Pore structure and fractal analysis of Lower Carboniferous carbonate reservoirs in the Marsel area, Chu-Sarysu basin

Autor: Zhengfu Zhao, Ke Wang, Kun Zhang, Xiongqi Pang, Xinhe Shao, Wei Li, Xue Zhang

Publikováno v: Marine and Petroleum Geology. 93:451-467

Evaluation of carbonate heterogeneity, closely related to pore geometry and connectivity, is important in oil and gas field production and reservoir prediction. To profoundly understand the heterogeneity of Lower Carboniferous carbonate reservoirs in
