“…To create a realistic representation of the Basin's subsurface hydrogeologic architecture, we based our model's hydrostratigraphy off Geldon (1989) and developed structure maps of the bottom of the shale-rich hydraulic barrier and top of the Precambrian basement (Figure S1 in Supporting Information S1). The structure maps were constructed using well lithology logs (COGCC, 2020;NMOCD, 2020), geologic maps (Baldwin & Muehlberger, 1959;Clark & Read, 1972;Fridrich et al, 2012;Garrabrant, 1993;Johnson, 1969Johnson, , 1974Johnson, , 1975Lindsey, 1995aLindsey, , 1995bLindsey, , 1996Pillmore, 2003;Vine, 1974;Wallace & Lindsey, 1996;Wanek et al, 1958) and Precambrian basement data (Hemborg, 1996). The stratigraphic data was interpolated using a natural neighbor algorithm to generate surfaces that encompasses the entire model domain.…”
