The Butler High-K method (Butler et al., 2003) is an appropriate solution for the analysis of slug tests performed in partially penetrating wells in formations of high hydraulic conductivity where oscillating effects are usually encountered in drawdown data. This exercise provides an example of slug test analysis using the Butler High-K method on oscillating drawdown data.
This exercise is written with the assumption that you have gone through the first exercise, and are familiar with the AquiferTest interface.
 Launch AquiferTest and choose the "Create a new project" button. If you already have AquiferTest open, create a new project by clicking the (New) button from the toolbar, or select File/New from the main menu.
 Create a new slug test by selecting Test > Create a Slug Test from the main menu. Select Slug Test 1 from the Tests Frame:
 Complete the fields for the Slug Test as follows:
In the Project Information frame:
•Project Name: Exercise 8
•Project No.: 8
•Location: Your Town
In the Slug Test frame:
•Name: High-K Butler Analysis
•Performed by: Your Name
•Date: filled in automatically
In the Units frame:
•Site Plan: m
•Discharge: U.S. gal/min
Aquifer Properties frame
 In the Wells table, a well has been created automatically. Ensure the type is Test Well which can be selected by clicking in the Type to produce a drop-down menu.
 Enter the following information for the well:
•Name: Well 1
The Slug Test tab should look like the image below:
 Click on the Water Levels tab to enter water level data for the test well
 In this test, you will import data from an excel file. Click the Import data... button
 The Open dialog will appear on your screen. Navigate to the folder
"C:\Users\Public\Documents\AquiferTest Pro\Exercises\Supporting Files\"
 Select the HighK_data.xls file and then click the Open button. The water level data will appear in the grid below
 In the Static WL [m] field type 0
 In the WL at t=0 [m] field, type 0.56
 Click the Refresh button from the toolbar. A graph of the drawdown appears to the right of the data grid, as shown below
 Click on the Analysis tab
 In the Analysis Name type “High-K Butler”. Notice that this name now appears in the Analyses frame of the Project Navigator Panel
 From the Analysis Method frame of the Analysis Navigator panel choose “Butler High-K”
 You may have to edit the Min and Max values for both axes so that the graph fits comfortably on the page. Time should range from 0-30 seconds, and the drawdown axis should range from -0.2 to 0.7.
 Click on the (Automatic Fit) icon, to fit the data to the type curve. The analysis graph should look like the image below:
 If you are not satisfied with the fit of the line, use Parameter Controls to adjust it.
 Once you are finished, the result in the Results frame of the Analysis Navigator panel should display the calculated conductivity value:
•K = 7.34E1 ft/d (73.4 feet/day), assuming an unconfined aquifer.
This completes the Butler High-K slug test analysis exercise. The next exercise will demonstrate how to use derivative analysis tool to help in identifying aquifer conditions and type curve matching. You have the choice of exiting AquiferTest or continuing on to the next exercise.
