Isopach Maps Show contour lines of thickness of a stratigraphic unit. Infill drilling is the practice of adding one or more wells to an existing field ofWater in the Dakota generally occurs in sandstone beds that are quite variable in thickness, areal extent, and degree of cementation. Consequently, irrigation development may be restricted to those areas where adequate quantities of water are obtainable.
