As can be seen in Figure 5-1, the pressure stabilized very rapidly at a pressure of about 1635 psia. The following morning, August 17, 1985, DST's consisting of two flow and two buildup periods were performed. The first flow period lasted about 31 minutes, and was followed by a 100-minute buildup period. During the buildup period, the pressure rapidly reached 1635 psia and stabilized. The second flow period lasted about 59 minutes, and was followed by a 128-minute buildup period. Again, the pressure rapidly reached 1635 psia during the buildup period and stabilized. The transducer was set at a depth of 2760.4 ft during these tests. The fluid in the well was a saturated brine having a specific gravity of about 1.2. Corrected for depth, specific gravity, and atmospheric pressure, 1635 psia corresponds to a pressure of about 190 psig at the surface. This pressure is well below the 288 psig measured before testing began, but intermediate between the maximum brine-reservoir pressure recorded (208 psig) and the brine-reservoir pressure measured just before the plug was set in 1983 (1 69 psig). The speed with which a constant pressure of 1635 psia was repeatedly reached during these tests indicates the presence of a constant-pressure source. This source is most likely the brine reservoir. The brine-reservoir plug is apparently not a perfect seal; pressure seems to be transmitted through the plug fairly readily. The fact that WIPP-12 wellhead pressures were higher than the pressure coming through the plug, however, indicates two things. First, the brine reservoir is not the source of the pressures measured at the surface. Second, any flow through the plug would be driven downwards into the brine reservoir by the higher pressures present above the plug. 5.1.2 Castile Tests. Following the plug tests, the DST tool was raised 39 ft and reset at the top of the Castile Formation. The bottom of the packer at this time was at a depth of 2735.5 ft. Figure 5-2 shows 42

WIPP-l2/Upper Castile and Plug Test Linear-Linear Sequence Plot the pressures measured during the subsequent testing. The tubing was swabbed to decrease the pressure in the test interval, and the test intenral was then shut in to allow the pressure to equilibrate. In less than an hour, the pressure was near stabilization at a value of almost 1614 psia. After a 15-minute flow period, the test interval was again shut in for a 64-minute buildup period. Again, the pressure was rapidly stabilizing at almost 1614 psia. The results of these tests are virtually identical to the results of the plug tests discussed in Section 5.1.1. The pressure in these tests stabilized about 21 psi lower than in the previous tests, but that was caused by the transducer being positioned 39 ft higher in the hole for these tests. Pressure transmitted from the brine reservoir through the plug appeared to be the dominating factor in these tests. No other pressure sources were noted in the upper Castile. 5.1.3 Salado Tests. The Salado tests were originally meant to be performed using a double- (straddle-) packer DST tool with a 100-ft separation between packers. Hole conditions proved to be such, however, that two good packer seats 100 ft apart could not be found. From August 19 to 23, 1985,17 attempts were made to set the DST tool and perform tests at depth intervals ranging from 1005 to 2200 ft. All of these attempts failed as fluid was able to bypass one or both packers. Only a single packer seat, from 11 15 to 11 20 ft deep between Marker Beds 102 and 103, was unequivocally good. During the course of these attempts, the DST tool was pulled up into the well casing and tested on four separate occasions. Each time, both packers set successfully with no apparent fluid leakage around them. Between the ninth and tenth attempts at testing, the tool was brought to the surface and all components were either replaced or rehabilitated. Our tentative conclusion from these failures is that hole closure since the original drilling in 1978 has caused fracturing in the rock around the hole that allows fluid to bypass any packer blocking the hole itself. 43
