The flow and bottomhole pressure data have been analyzed for the two sands (Nos. 8 and 9) tested by the Gladys McCall No. 1 Well. The more productive sand (No. 8) appears to be bounded by two linear faults at distances of approx.740 ft and approx.1360 ft from the well and there appears to be a decrease in the formation transmissivity away from the well. The formation properties inferred from the well test analysis have been used with a reservoir simulator to match the bottomhole drawdown/buildup history measured during the Reservoir Limits Test of Sand Zone No. 8. Wellhead pressure data measured during the long-term production testing of Sand Zone No. 8 have been employed to estimate the corresponding downhole pressures. The simulation model based solely on the Reservoir Limits Test is found to be in remarkably good agreement with the estimated bottomhole pressures for the first six months of production testing, but enlargement of the reservoir volume, by moving the boundary most remote from the well outward, is required to adequately match the full production history. The added remote volume corresponds to an increase by a factor of three in the estimated reservoir volume. The results for the Gladys McCall well are discussed in the context of earlier results determined from testing the other through geopressured geothermal design wells (Pleasant Bayou No. 2, Amoco Fee No. 1 and L.R. Sweezy No. 1 Well). 12 refs., 36 figs., 7 tabs.
