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.
Constant-duration pumping tests are a better method of analyzing the The simplest way of dealing with slug-test data is to plot displacement versus time.
A pneumatic slug test eliminates cross-contamination of wells, reduces equipment contact with water that may be hazardous, and allows testing where a traditional slug test may be prohibited. While initial equilibration can take time in a pneumatic test, the slugging event is nearly instantaneous.

Testvapnet ska inte med på jakt utan den provar jag enbart på skjutbanan Jag har hittills nog aldrig hittat en pump eller halvauto som jag tyckt varit lika Jag sköt hagel och slug med vikter från 24g upp till 36g och den enda
A slug test involves the abrupt removal, addition or displacement of a known volume of water and the subsequent A considerable body of data has been amassed that indicates that the K estimate from a pumping test is, on average, considerably larger than the estimate obtained from a series of slug tests in the same formation. Although these data could be interpreted as indicating a natural underlying scale dependence in K, an alternate explanation is that the slug‐test K is artificially low as a result of incomplete well development and, to a much lesser extent, failure to account for vertical anisotropy.
Slugtest är den enklaste metoden. Pumpvolymen justeras med målsättning att hitta en jämviktssituation där pumpningen och tillrinningen är lika stor.

The hydraulic conductivity test system provides high-quality data for accurate determination of formation hydraulic conductivity (K).

Abstract. In most field investigations, information about hydraulic conductivity (K) is obtained through pumping or slug tests. A considerable body of data has been amassed that indicates that the K estimate from a pumping test is, on average, considerably larger than the estimate obtained from a series of slug tests in the same formation.
