Breakthrough of shallow shale gas exploration in Taiyang anticline area and its significance for resource development in Zhaotong, Yunnan Province, China

Integrated Assessment Modeling of China’s Shale Gas Resource: Energy System Optimization, Environmental Cobenefits, and Methane Risk

“…China's domestic shale gas research mainly focuses on four themes: first, the potential of shale gas resources [53][54][55][56][57]; second, shale gas development in consideration of the current technical difficulties and mining costs [46][47][48], focusing on technological innovation; third, the positive influence of shale gas, which focuses on its energy substitution [20][21][22] and carbon reduction [20,[22][23][24][25] effects; fourth, the negative impact of shale gas [24,25]. The position of our study in the literature is that we consider all the four aspects and the positive and negative effects, and highlight the atmospheric environmental impact.…”

“…What's more, we noticed that the use of shale gas will be challenged in other ways [42]. Including the social influence and public attitude [11,43,44], shale gas extraction, recovery and reuse technology [45][46][47][48][49][50], government subsidy pressure [51,52], and so on. At the social impact level, the study of Cooper J et al [11] in the United Kingdom shows that the use of shale gas can bring employment opportunities and financial benefits to local communities, but it needs to overcome social barriers such as low public support.…”

“…While in Weiyuan County, China [44], nearly half of the people were found to support relevant policies, a very small number completely oppose it. In terms of shale gas extraction, recovery and reuse technology, the problem that has always been explored is how to determine the potential and limitations of shale gas [46][47][48] through various technologies, and improve shale gas recovery rate by carbon dioxide injection technology [49] and heating treatment [50]. In addition, there are concerns about government subsidies for shale gas use in China; Liu J. et al [51] and Bai Y. et al [52] showed that shale gas development needs subsidies in the early stages, and fiscal subsidies are effective incentives for shale gas investment.…”

Occurrence of Irreducible Water and Its Influences on Gas-Bearing Property of Gas Shales From Shallow Longmaxi Formation in the Xishui Area, Guizhou, Southern China

“…After the commercial development of the Longmaxi shale gas in the Sichuan Basin, southern China (Li and Zhang, 2015;Guo, 2016), the exploration of shallow marine shale gas outside the Sichuan Basin has made significant progresses. For instance, the GIP content of the Longmaxi shale in the Zhaotong Block, Yunnan Province can reach 3.81 m 3 /t, with an initial gas production of 0.39-1.12 × 10 4 m 3 /d although its burial depth is less than 1,000 m (Tian, 2018;Yang, 2018;Liang et al, 2020). The shallow marine shale gas in southern China is expected to become a new exploration field (Li, 2018;Liang et al, 2020).…”

Reservoir Characteristics of the Lower Silurian Longmaxi Shale in Zhaotong Region, Southern China

“…The Changning, Weiyuan, Zhaotong, and Fuling marine shale gas demonstration zones achieved a combined annual output of 79 × 10 8 m 3 in 2017 [8]. China has great potential for additional shale gas exploration, and the production of shale gas in the country is forecast to reach 800 -1000 × 10 8 m 3 by 2030 [9].…”
