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.

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. A slug test consists of inducing an instan- taneous change in water level in a well, whereas a pumping test involves withdrawing water out of a well at a con- trolled, generally constant, rate.

(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

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.

Often slug tests are performed instead of a constant rate test, because: time constraints (quick results, or results for a large number of wells, are needed), the well does not or cannot have a pump installed on it (slug tests do not require pumping), SLUG TESTS Slug tests are generally conducted to determine the horizontal K of a ground water zone. A slug test involves the abrupt removal, addition, or displacement of a known volume of water and the subsequent monitoring of changes in water level as equilibrium conditions return.

ANALYSIS OF A "SLUG TEST" OR DRILL STEM TEST FOR LINEAR FLOW A. Barelli ENEL, Ttaly INTRODUCTION t I \ The objective of this work is to provide a means for analyzing pressure transients from drill stem tests (DSTS) in fractured wells dominated by linear flow in the formation. Author: mkoenig Created Date: 3/6/2018 3:11:21 PM 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. Completing a Pneumatic Slug Test Well-head Assembly Pulse tests can be used to determine the same information as interference tests.

pumping tests. Pump tests values are generally considered to better represent aquifer behavior (Butler and Healey, 1998). A slug test induces a rapid change in water level in a slugged well, and then one observes how fast the water level returns to equilibrium. The

In the Theis analysis, the transmissivity (T) and storativity (S) were calculated. In Hvorslev analysis, it is conductivity (K). En fläkt i pumpen drar till sig den varma ventilationsluften som finns i huset. I pumpen cirkulerar det en vätska som ”fångar upp” ventilationsluften. En kompressor utvinner värmen från luften som leds in i en kondensor. Värmen i kondensorn sprids till husets värmesystem, till exempel element och till varmvatten. COP- och SCOP-värde 2019-11-18 · Slug test initiation involves raising or lowering the water level in the control well as rapidly as possible.
