From June 1981 through August 1984, four deep hydrogeologic test wells were drilled in the Palo Duro Basin of Texas. The wells were part of an area characterization program to evaluate the basin for suitable high-level radioactive waste repository sites. Pumping test data from four wells, Sawyer No. 1, Mansfield No. 1, Zeeck No. 1, J. Friemel No. 1, have been analyzed using numerical simulation and type-curve comparison techniques. The testing procedure consisted of several pumping cycles. Each cycle consisted of a period of constant-rate pumping followed by a period of recovery. A method was developed to include the effects of prior cyclic pumping/recovery history while recovery for each cycle was plotted. From the recovery curves, preliminary values of transmissivity and initial formation pressure were estimated, and aquifer boundary configurations were assessed. This preliminary information was used as initial input to a finite-element model of the test zone, and parameters were refined through trial and error until an acceptable match between modeled and actual curves was obtained. 15 refs., 138 figs., 40 tabs.
