Flow logs of the multi-zone wells were collected under steady-state ambient and pumped conditions with heat-pulse and electromagnetic flowmeters.  The combined measurement range of the high-resolution flowmeters configured with fully-fitted diverters spanned flows encountered under ambient and low-rate pumped conditions. Flows under high-rate pumped conditions in large-diameter test and production wells were measured with the electromagnetic flowmeter configured without a diverter or with an underfit diverter.  Wellbore-diameter, acoustic- and optical-image, and fluid-property logs served as guides for the collection and interpretation of the flow logs.  Model analysis of the ambient and pumped flow logs along with drawdown data provided estimates of the transmissivity and hydraulic head of the flow zones. 

Fluid-property logs collected under the same ambient and pumped conditions were interpreted along with the flow logs to determine the quality of water from the flow zones.  Depth-dependent samples for water quality and specific-ion logs from newly developed multi-parameter probes supplemented traditional fluid resistivity and temperature logs.

Integrated flow and fluid-property logging for well evaluation and flow-zone characterization in the Paleozoic (New York), Floridan (Florida and South Carolina), and Edwards (Texas) carbonate-bedrock aquifers will be presented.  Case studies will demonstrate applications in test wells for hydraulic characterization and design of discrete-zone head and water-quality monitoring installations, and applications in monitoring and production wells for saltwater intrusion and other non-point contamination assessments.
