...Zonghu Liao; Lin Zhang; Long Wen; Lianbo Zeng Abstract Seismic survey data collected for coal gas exploration show that there are many collapse columns distributed in the subsurface of Qinshui Basin, China. The interesting features of the collapse columns are observed by the seismic attributes...

... constrained petrophysical and mechanical properties of a CBM reservoir from the southern Qinshui Basin (SQB), northern China, have been investigated by using a coal structure index ( CSI ). The CSI was established as a quantitative criterion for the deformation of SDCs based on surface conditions...

... seismic curvature data to the results of 221 core samples from the Zhengzhuang field in the southern Qinshui Basin, we provide a seismic curvature attribute-based coal texture evaluation method. Evaluation of the results shows that the coal texture types of the no. 3 coal seam include undeformed coal...

... and the current study area, the Qinshui Basin) typically have much lower permeability than conventional reservoir rocks elsewhere; it is therefore necessary to rely heavily on reservoir fracturing for economic CBM production ( Fu et al., 2007 ; Chen et al., 2013 , 2014 ). The brittleness index (BI...

...Qiang Chen; Sheng Zhang; Suoliang Chang; Bo Liu; Jun Liu; Jianhui Long ABSTRACT A subsurface landslide is the key problem to a large affordable home program in the southern Qinshui Basin, China. A geophysical survey integrated with seismic refraction tomography (SRT), seismic scattered wave imaging...

...Jiyuan Wang; Shaobin Guo Abstract To systematically study the whole-aperture pore-structure characteristics of the marine-continental transitional shale facies in the Upper Palaeozoic Taiyuan and Shanxi Formations of the Qinshui Basin, we have collected a total of 11 samples for high-pressure...

...Difei Zhao; Guo Yinghai; Shuai Yin; Chengyao Ren; Yujie Wang Abstract Using the tight sandstone of the lower Permian Shanxi Formation in the southern Qinshui Basin as an example, we have developed the concept of “geomechanical sweet spots” in a strongly deformed strike-slip fault zone...

...Mingjun Zou; Chongtao Wei; Xuehai Fu; Yuan Bao; Zhixiang Cai Abstract Based on the characteristics of seven representative coalbed reservoirs in the Qinshui Basin in Shan’xi Province, China, the reservoirs were classified as gas pressure reservoirs, water pressure reservoirs or hybrid pressure...

...Xianbo Su; Xiaoying Lin; Mengjun Zhao; Yan Song; Shaobo Liu Abstract The coalbed methane resource is very abundant in Qinshui basin (3.28 × 10 12 m 3 ; 114 tcf). The investigation on the upper Paleozoic coalbed methane system is a guide to the exploration and development of coalbed methane...
