..., the Shixi–Mobei Uplift is a key area for oil and gas exploration. This study examines the geological and depositional characteristics of the Sangonghe Formation using cores, microscopy, mineral analysis and seismic profiles. The Sangonghe Formation represents the peak of lacustrine transgression...

... the Junggar, Turpan-hami, and Santanghu Basins, and covers an area of 42.5×10 4 km 2 . Most oil and gas fields are located in the Junggar and Santanghu Basins, with accumulations in Carboniferous age reservoirs (e.g. the Chepaizi and Shixi Oil Field), the Kelameili Gas Field in the Junggar Basin...

... and marginal lacustrine environments. The palaeosol and calcretes primarily occur in the Jiande Group, Yongkang Group, Qujiang Group in the basins of western Zhejiang and Shixi and Luotang Formations in the basins of NE Jiangxi. The Jiande Group comprises the Laocun, Huangjian...

... of Dinan bulge in Junggar basin, China (see Fig. 1 ). It extends to the east of Karamaly mountain and connects to west Shixi bulge. The area also approaches Dongdaohai riding in the south and connects to Dishuiquan riding in the north. Dx is underlain by volcanic and sedimentary rocks...

..., Shixi, Cainan, and Shanan oil fields have subsequently been found. Recent work shows that more than 90% of the petroleum resources of the basin are located in the central part of the basin ( Cai and Liu, 2005 ) but the discovery rate is still low ( He et al., 2004 ). The study area is situated mainly...

.... Northern Guizhou has the characteristics of a medium-to-low geothermal field, with an average heat flow of 64 mW/m 2 and an average geothermal gradient of 24°C/km [ 65 ]. It experienced uplift at the Late Cretaceous [ 66 ]. By combining the burial–thermal history with the trapping temperatures...

... the field fracturing due to the limitation of equipment load and samples size. In order to comprehensively consider the influence of engineering and geological factors on fracturing, numerical simulation technology has been developed and widely used. The commonly used numerical methods mainly include...

... of Exploration and Development, PetroChina Southwest Oil and Gas Field Company. The samples for thin-section observations were doubly polished to a thickness of approximately 0.03 mm. Microscopic observations of thin sections for petrology, mineralogy, and hydrocarbon shows were conducted under...

... intervals of the Bashituo oil field and the potential source rocks in the depression. Shaded rectangular and gray-shaded rectangles show the reservoir intervals and potential source rocks. Gas chromatography of the saturate fractions was performed using an Agilent Model 6890 gas chromatograph...

..., was examined in this study through petrographic and geochemical analyses as well as geochemical modeling. Field and petrographic work recognized four paragenesis stages in the Jinshan deposit: (1) quartz (Q1)-carbonate, (2) pyrite-quartz (Q2), (3) gold-polysulfide-quartz (Q3)-carbonate, and (4) chlorite-quartz...
