(1998) conducted slug test in wells with partially submerged screens. The slug test presents numerous pros, but also some cons. Indeed, the reliability of a slug test is less than a pumping test that, when it is possible to use, undoubtedly more accurately estimates perme-ability. A slug test is simple, fast, inexpensive and does not require Spreadsheets for the Analysis of Aquifer-Test and Slug-Test Data, Version 1.2. By Keith J. Halford and Eve L. Kuniansky. Preface. This report documents several spreadsheets that have been developed for the analysis of aquifer-pumping test and slug-test data.

Regardless of whether a slug test is performed in a conventional (Figure 1a) or multilevel (Figure 1b) format, the pneumatic method [Prosser, 1981] is most appropriate for test initiation in highly permeable intervals (see Appendix A). Given the short duration of slug tests in highly permeable aquifers, a test will have on the aquifer system. It is not the intent of this section to give a detailed explanation of every aquifer test and its limitations, but rather to review basic terminology and provide the fundamental concepts for conducting an aquifer test.

values. This transducer recorded the slug test signals for quantitative analyses. For rising slug tests, the aluminum pipe was pressurized with nitrogen (N2) gas; for falling slug tests the aluminum pipe was depressurized with a vacuum pump. The 2.5 cm (1 inch) wellhead fitting accommodated the slug test transducer cable, the gas line, and a slug test in a well with a skin Of finite thickness. The solution was found in the Laplace domain and type curves were obtained by numerical inversion. Using realistic values of aquifer and skin hydraulic properties, we show the effects Of a finite- INTRODUCTION The slug test is known to be a valuable pumping tests. Pump tests values are generally considered to better represent aquifer behavior (Butler and Healey, 1998).
