H-lG/Culebra Second Buildup Dimensionless Horner Plot with INTERPRET Simulation Figure 5-46 shows a semilog plot of the rising-head slug-test data, along with the best-fit type-curve match. The match shown provides a transmissivity estimate of 0.69 ftz/day (Table 5-3), slightly lower than the estimates from the DST analyses. The static formation pressure estimate of 134.8 psia used to achieve the fit in Figure 5-46 is also slightly lower than the values used in the DST analyses. This decrease probably indicates continued dissipation of an overpressure skin. A comparison of the static formation pressure indicated by the slug test with the pressures measured by the transducer installed at the Culebra horizon as part of the H-16 5-packer completion (Figure 3-8) may also indicate the continued presence of an overpressure skin during the DST's and slug test. The transducer used for the DSTs and slug test was set at a depth of 678.6 ft. H-16 contained water having a specific gravity of 1.02 at the time of the Culebra testing. The slug-test pressure of 134.8 psia reduces to 121.1 psig when the atmospheric pressure of 13.7 psia measured by that transducer is subtracted. The corresponding formation pressure at the midpoint of the Culebra 712 ft deep is about 136 psig. In contrast, the Culebra transducer of the 5-packer system, which is located at a depth of 702.6 ft, 24 ft deeper than the DST transducer, showed a pressure stabilization at 128 psig shortly after the 5-packer installation was completed (Stensrud et al., 1988). With the hole now containing brine having a specific gravity of 1.2, the corresponding formation pressure at the midpoint of the Culebra, 712 ft deep, is 133 psig. Hence, about 3 psi of additional pressure-skin dissipation may have occurred after the Culebra testing was completed. Alternatively, continued leakage of Culebra water into the WlPP shafts may have lowered the Culebra formation pressure at H-16. 5.2.2.8 H-17. Testing of the Culebra at H-17 was planned to determine whether or not the well had been successfully located in an area of high Culebra transmissivity. The Culebra lies from 705.8 to 731.4 ft deep at H-17 (Figure 3-9). The interval tested extended from 703.1 ft to the then-bottom of the hole 81
