H-l8/Culebra First Buildup Dimensionless Homer Plot with INTERPRET Simulation The log-log plot of the SBU data (Figure 5-56) also shows overpressure skin effects as a decline in the derivative at late time. The simulation shown is similar to that developed for the FBU, and is representative of a single-porosity medium with a transmissivity of 2.2 ftZ/day (Table 5-3). The skin factor for this simulation is -1.0, showing increased stimulation during the DST's. The overpressure skin caused the pressure to peak at 155.0 psia after 70 minutes of the SBU (Figure 5-53). The dimensionless Horner plot of the SBU data (Figure 5-57) shows that the overpressure skin was initially driving the recovery toward a static formation pressure of 156.1 psia, but that at late time the data deviated toward a lower pressure as the rates of pressure-skin dissipation and pressure recovery became more equivalent. Figure 5-58 is a semilog plot of the rising-head slugtest data, along with the best-fit type-curve match. This match provides a transmissivity estimate of 1.7 ftz/day, slightly lower than those provided by the DST buildup analyses (Table 5-3). During the slug test, the pressure appeared to be recovering to a value of 154.5 psia, slightly lower than the final SBU value. The transmissivity values provided by the DST's and slug test of about 2 ftZ/day indicate that H-18 lies in a transitional region between the higher transmissivities to the north and the lower transmissivities to the south. Based on experience with similar transmissivities at H-3 (Beauheim, 1987a), the Culebra at H-18 might be expected to show double-porosity effects in its hydraulic responses. Fractures in the Culebra core from H-18 further indicate a potential for double-porosity behavior. No double-porosity behavior was observed, however, perhaps because the small spatial scale and the short test durations involved in DST's and slug tests allow for little interaction between fractures and matrix. A pumping test of several days' duration would provide a more definitive indication of whether or not the Culebra behaves hydraulically as a double-porosity system at H-18. 88
