Effective Exploitation Potential Of Shale Gas From Lower Cambrian Niutitang Formation, Northwestern Hunan, China, Han Cao, Tianyi Wang, Ting Bao, Pinghe Sun, Zheng Zhang, Jingjing Wu

Michigan Tech Publications

The marine shale in the Lower Cambrian Niutitang Formation is the dominant shale-gas reservoir in northwestern Hunan, which accounts for more than 70% of unconventional energy in Hunan province. Accurately evaluating the shale-gas exploitation potential is a key to determining whether commercial exploitation standards can be met. In the literature, most existing studies have focused on evaluating the shale-gas exploitation potential based on either accumulation conditions or the shale fracability, which will lead to a gap between the real production and proven gas reserves due to the characteristics of the shale’s low permeability and low porosity. Therefore, further studies are …
