| Description | Journal: Iop Conference Series: Earth and Environmental Science The hydrogen and oxygen isotopes of the fracturing flowback fluids from 3 wells in the Longmaxi Formation in Dazu area of western Chongqing, China provides insights into the source of the flowback fluids. We use the valued of $δ^{2}$H and $δ^{18}$O, combined with concentrations of ions to discuss the changing rule of H and O isotopes throughout the flowback period. The values of $δ^{2}$H and $δ^{18}$O for Z2 and Z5 wells show different changing trends. But he values of $δ^{2}$H and $δ^{18}$O for Z2 and Z5 wells have similar changing trends. There is no obvious correlation between hydrogen and oxygen isotopes for 3 wells. The fracturing fluids, formation brines, meteoric water, and water-rock reaction can change the H and O isotopes for flowback fluids from shale gas wells. |
