Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4043628-MS
... porosity, permeability and mechanical properties under temperature and pressure effects. 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...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4043959-MS
... 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...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 17–19, 2024
Paper Number: URTEC-4043775-MS
... 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...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 20–22, 2022
Paper Number: URTEC-3722421-MS
... 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...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 26–28, 2021
Paper Number: URTEC-2021-5267-MS
... 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...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 20–22, 2020
Paper Number: URTEC-2020-2443-MS
... 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...

Paper Number: URTEC-2882313-MS
... 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...
