摘要：

Oxygen isotope compositions of formation waters from drill stem tests and produced waters are reported from the Yeoman and Duperow aquifers across the Williston basin. Mapped isotopic distributions vary across the basin from <- 24 parts per thousand delta(18)O to values over + 9.4 parts per thousand delta(18)O, relative to Standard Mean Ocean Water (SMOW). Areal distributions of oxygen isotopes support a complex model of paleohydrogeology of the basin. They can be used to trace meteoric recharge into the basin, identify slow or stagnant brine-flow areas, and the presence of glacially induced recharge water deep in the subsurface.
