Abstract:

Fracturing water and flow back water samples were obtained in a shallow vertical shale well (28°15′50″N, 106°6′2″E; well depth of 704 m) drilled into the marine shale in Xishui County of Guizhou Province of China in 2019. In parallel, laboratory water-rock interactions experiments with water/rock ratio of 2:1 at the reservoir temperature of 28℃ were conducted to verify data trends observed in the field data. Physical parameters and chemical and isotopic compositions of water samples from field and laboratory were analyzed to obtain the In Situ Sample for Hydraulic Fracturing and Laboratory Analysis Dataset in Xishui County of Guizhou Province of China. The dataset includes: (1)Geo-location of the sample; (2) the physical parameters and chemical and isotopic compositions of fracturing water (FRW) and flow back water (FBW) (Tab.1); (3) water rock interaction experiments between deionizer water and shale with water/rock ratio of 2:1 (Tab.2); (4) water rock interaction experiments between fracturing water (FRW) and shale with water/rock ratio of 2:1 (Tab.3); (5) the nitrate adsorption/desorption experiment (Tab.4). The dataset is archived in .xlsx, .kmz, and .shp data format, and consists of 8 data files with data size of 31.3KB (compressed to 28.7 KB in one file).
