Inflatable straddle packers were used to isolate and test 19 intervals ranging from 56 to 747 meters (183 to 2,450 feet) each in hole UAe-2, Amchitka Island, Alaska. Packer seats were poor in part of the hole because of unstable wall conditions. Thus, some zones had to be tested several times.
The static water levels in the intervals tested ranged from 14.2 meters (46.6 feet) below land surface in the upper interval to 33.7 meters (110.6 feet) below land surface in one of the intervals near a depth of 1,500 meters (4,900 feet).
The specific capacity of the open hole from 83.5 to 1,980.6 meters (274 to 6,498 feet) was 3.26 cubic meters per day per meter (0.182 gallon per minute per foot) of drawdown after the hole had been jetted at an average rate of 763 cubic meters per day (140 gallons per minute) for about 41 hours. Transmissivity computed from the recovery of water level after jetting stopped was 2.97 cubic meters per day per meter (239.2 gallons per day per foot).
The relative specific capacities of isolated intervals ranged from 0.001 cubic meter per day per meter (less than 0.001 gallon per minute per foot) of drawdown to 2.765 cubic meters per day per meter (0.155 gallon per minute per foot) of drawdown.
