WebbWater flow rates and potentiometric surfaces (or piezometric levels) were inferred from drill stem test information acquired from McAllister and Associates of Calgary. Only tests with water recovery were considered after discarding misruns and unsound tests. The flow rates were estimated on the basis of a drawdown of 300 m. Webbthe contours on it suspended in space. The projection on the bottom surface (the xy-plane) shows the triangle of Figure 6. Also shown is the projection on the xz-plane, a side view. The contours would be horizontal lines on this projection. A B C Figure 7. Three-dimensional context of the representation shown in Figure 6. (See also Isaaks
