Abstract
Independent aquifer testing is the only way to fully understand the hydrology encountered in boreholes intersecting multiple aquifers. The most feasible method to accomplish the testing of multiple aquifer wells is through the use inflatable packers. The straddle packers and associated equipment herein described arE valuable tools for making isolated aquifer tests as well as conducting hydraulic fracturing experiments. The system, due to design, permits multiple tests in a bore-hole without the necessity of tripping in and out of the hole to redress the packers prior to testing each zone. Electronic pressure transducers, the output of which was fed into strip-chart recorders, were used to monitor the zone being tested, as well as to monitor the zones above and below the packers. This was necessary to ensure that no leaking had occurred around the packers, causing hydraulic continuity between the isolated zones.
