The slug test is the most widely used technique for the in situ estimation of on repeat slug tests and not the clarity of pumped water; (2) the effective screen of the Bouwer and Rice method of slug test analysis: Water Resources
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. The measurements are recorded and analyzed by one or more

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.

The resulting data was very smooth, distinguishable (no oscillation or pressure wave) and easy to process. As defined by Fetter (1994) a slug test is “an aquifer test made by pouring a small instantaneous charge of water into a well or by withdrawing a slug of water from the well” (e.g with a bailer). This definition clearly shows how early slug testing was conducted, by quickly adding water to a well or quickly removing a bailer full of water from the well. 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.

A slug test is simple, fast, inexpensive and does not require
A slug test is in contrast to standard aquifer tests, which typically involve pumping a well at a constant flowrate, and monitoring the response of the aquifer in nearby monitoring wells. 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),
A slug test consists 4815 of inducing an instantaneous change in water level in a well, whereas a pumping test involves 49 withdrawing water out of a well at a controlled, generally constant, rate. For both kinds of 50 hydraulic tests, water level response is measured in one or more surrounding observation wells
An aquifer test is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" in observation wells.

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
time) – Substitute water level vs. time data and well geometry parameters into a mathematical model to solve for K 2019-11-17 · A pumping test is a field experiment in which a well is pumped at a controlled rate and water-level response ( drawdown) is measured in one or more surrounding observation wells and optionally in the pumped well (control well) itself; response data from pumping tests are used to estimate the hydraulic properties of aquifers, evaluate well An aquifer test is conducted to evaluate an aquifer by "stimulating" the aquifer through constant pumping, and observing the aquifer's "response" in observation wells. Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries. A slug test is a variation on the typical aquifer test where an instantaneous change is made, and the effects are observed in the same well. This is often used in geotechnical or 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.
