Geochemistry of Formation Water and Implications for Ultradeep Tight Sandstone of DK Gas Field in Kuqa Depression by Xiaobo Guo, Libin Zhao, Wei Han, Longfei Zhou, Zhilong Huang, Xiongwei Sun, Xuejun Yang, Tonghui Zhang, Chenglin Zhang

“…The formation water may have been influenced by early seawater, but it is not significant and is more likely to have been influenced by water seepage from the overlying gypsum strata. The Sr, H, and O isotopes reveal that the different types of formation water have good homology and are not affected by atmospheric precipitation, which is propitious to the preservation of natural gas.…”
