Summary
Description
These data represent the interpretations from borehole electric (resistivity) logs from oil and gas wells and lithologic logs from nearby water wells. These interpretations were used to build the hydrogeologic framework in the Williston structural basin. The resistivity logs were used to identify the hydrogeologic units (fig. 3A of SIR 2014-5047) and to quantify the vertical detailed lithology (thickness of sand, coal, gravel, silt, and shale) in the oil and gas exploration boreholes.
