To address this gap, we conducted experiments by collecting core samples from optimal intervals of typical Silurian deep shale gas reservoirs in the Sichuan Basin, China. Due to sedimentary microfacies variations...

... Abstract Since the Late Paleozoic, China's primary basins have evolved into lacustrine basins, fostering high-quality shale formations in semi-deep to deep lake facies. This study investigate the lacustrine shale characteristics of the Jurassic Ziliujing Formation within the Sichuan Basin...

... Abstract Three shale gas fields, Fuling, Weirong, and Wulong, in the Sichuan Basin exhibit significant differences in the production performance of the Wufeng-Longmaxi shales. This study investigates the total organic carbon (TOC) content, mineralogical properties, and organic matter (OM) pore...

..., and coal bed methane. Shale gas, as a clean energy source, has good development potential and value [2] , and China has abundant shale gas resources [3] , mainly concentrated in the Sichuan Basin and the Ordos Basin [4] . The Sichuan Basin, as the main area of shale gas resources in China and one...

... in laminated reservoirs using an integrated reservoir-geomechanics-fracture model. Using a dataset from the Sichuan Basin, Western China, a multilayer deep shale gas reservoir model is built with 4 horizontal parent wells spaced at 450 m in the lower producing layer and child wells to be placed in upper...

... Abstract Fluid typing identification is one of the greatest challenges in Sichuan Basin, China. To solve this problem, various borehole measurements are introduced by operators, such as nuclear magnetic resonance and array dielectric logs. These measurements are barely satisfactory...

... Abstract Shale hydration is an important factor affecting the productivity and flowback rate of shale gas wells. In this paper, we conduct a set of experiments on shale sample from the Longmaxi Formation (LF) located in the Sichuan Basin. The experiment of shale hydration was carried out...

... Abstract The Upper Triassic Xujiahe formation is very tight formation located in highly tectonically stressed zones in the Western Sichuan Basin of China. The second and fourth members (abbreviated as T3X2 and T3X4, respectively) of the Xujiahe formation are gas-bearing tight sandstones...

... Abstract A large shale gas reserve has been discovered in the deep Longmaxi reservoir in Sichuan basin, western China, which is anisotropic, tectonically stressed, largely naturally fractured, and under complex geological structure. Successful development of the deep shale gas resources relies...

... of variations of mineral constituents and depositional features indicates sedimentary facies distribution. The Lower and Upper WuFeng-LongMaxi Formation was studied in 27 wells spanning 100 km west-east across the southern SiChuan basin. From elemental spectroscopy, argillaceous, carbonate, and siliceous...

... Abstract Most bedding-parallel fractures in the WuFengLongMaxi Formation, SiChuan basin, are calcite filled and commonly show slickensides, which features characterize bedding-parallel shear fractures. Such fractures can serve as flow channels and storage spaces in gas shale reservoirs...

... Abstract Out of the 101 wells in the Changning and Weiyuan shale gas blocks in Southwest China's Sichuan basin drilled before March 2016, casing deformation occurred in 32. Analysis of one of these wells shows a fault at a sheared casing location, which suggests that hydraulic fracturing...

... Abstract Outcrops reveal extremely complex geometries and distributions of natural fractures at various scales in the Ordovician-Silurian Wufeng-Longmaxi shale formation in South Sichuan basin. Field experiences suggest natural fractures can significantly affect efficiency of drilling...

... Summary One of the significant challenges in the characterization of the Cambrian Longwangmiao Formation, Sichuan basin, South West China was to recognize the lateral and vertical variability of lithofacies and secondary porosity development and then construct the spatial distribution trends...

Exploration achievements indicate that the discovered gas in Leikoupo Formation are mainly distributed around gypsum pots...

... Summary The Wufeng-Longmaxi Shale, Upper Ordovician and Lower Silurian marked by a widespread transgression in Yangtze Platform region are unique with highly thermal maturity, tectonically complex setting and significantly variable in-situ stress field. The Sichuan Basin with comparatively...

... Abstract The Fuling shale gas field within the Sichuan Basin, Southwestern China, is the first major commercial discovery of shale gas outside of North America in the world, with proven gas reserves of 3,769.85 billion ft 3 , by the July of 2014. The gas occurs in the lower Paleozoic Wufeng...
