Thus, the lower 2.7 ft of the Tamarisk and the upper 3.6 ft of the unnamed lower member were tested along with the Culebra. These overlying and underlying intervals are composed of anhydrite, gypsum, and/or clay, and were not considered to have contributed significantly to the transmissivity measured during the Culebra testing. The H-17 Culebra testing was performed from October 9 to 12, 1987. The testing consisted of two DST flow periods, two buildup periods, and a risinghead slug test (Figure 5-47). The FFL lasted about 16 minutes, and was followed by a 449- minute FBU. The SFL lasted about 24 minutes, and was followed by a 939-minute SBU. To obtain constant flow rates for buildup analyses, the FFL was divided into two flow periods having rates of 0.368 and 0.259 gpm, and the SFL was divided into two flow periods having rates of 0.443 and 0.280 gpm (Table 5-1). The slug test lasted about 48 hr, by which time about 99% of the induced pressure differential had dissipated. The data from these tests are presented in Stensrud et al. (1988). A log-log plot of the FBU data is presented in Figure 5-48, along with a simuiation generated by INTERPRFT. The simulation is representative of a single-porosity medium with a transmissivity of 0.21 ft*/day (Table 5-3). Assuming a Culebra porosity of 20%, a total-system compressibility of 1.0 x 10-5 psi-’, and a fluid viscosity of 1.0 cp, the skin factor for this simulation is -1.5, indicating a moderately stimulated well. The decline in the pressure derivative at late time indicates the presence of an overpressure skin created during coring and reaming of the Culebra October 7 and 8, 1987. The dimensionless Horner plot of the FBU data (Figure 5-49) also shows the effects of the overpressure skin as the data trend slightly upward at very late time towards a pressure lower than the 145.5 psia specified as the static formation pressure for that simulation. In fact, the buildup pressure reached a maximum of 144.8 psia after 275 minutes of the FBU (Figure 5-47), and declined slightly thereafter. The data collected after the maximum pressure was reached are not included on the analysis plots. 82
