In the Palo Duro basin, the problems of the hydrogeologic setting are reduced by delineating regions with little variation in surface topography and structure. The P-D plots for these different regions vary considerably. To evaluate the effect of the hydrogeologic setting on these P-D plots, theoretical models of hydrostatic conditions were computed for the hydrogeologic setting of each region. Comparison of regression lines through real P-D data to those through modeled data distinguishes true hydrologic conditions from the misleading effects of the hydrogeologic setting. P-D plots indicate regional underpressuring in Palo Duro basin. Variations in potential vertical flow within the underpressured basin are indicated by variations in P-D gradients across the basin. Potential upward flow is indicated along the western flanks of the Amarillo uplift, while potential downward flow is indicated in the southwestern and eastern parts of the basin.
