Hydraulic testing and sampling of hole Ue-1 in central Nevada

Hydraulic testing and sampling of hole Ue-1 began on January 31, 1967, and ended on February 13, 1967. Depth intervals tested and sampled were: zone 1, 1,710 feet to total depth; zone 2, 1,508 to 1,706 feet; zone 3, 1,266 to 1,464 feet; zone 4, 788 to 986 feet; and zone 5, 400 to 598 feet. 

Injection and recovery tests were run on each depth interval. Relative specific capacities calculated from injection data were much smaller than those calculated from recovery data. More mud and lost circulation material in the hole and in the formation during the injection test account for the different relative specific capacities. 

Comparative composite hydrostatic heads before and after the injection and recovery tests were 211.5 feet below lsd (land-surface datum) and 218.0 feet below lsd. The difference may be due to differences in the conditions of the measurements. 

Of the five zones tested, only zone 5 did not have at least partial communication around the bottom packer.
