The best part is that the Hi-K kit provided excellent results with smooth test data that was free of early oscillations typical of solid slug tests. Finally, slug-test theory was extended to include double-porosity effects coupled with wellbore storage and skin. The following is a short summary of the development of slug-test analysis. Ferris and Knowles presented an application of the instantaneous slug-test solution for determining formation transmissivity.

Ett slug-test mäter hydraulisk konduktivitet i en akvifer genom ett borrhål, vilket gör att uppskattningen av akviferens material bara blir till den del man borrat i.

Slugtest är den enklaste metoden. Principen är att släppa ner ett Examensarbete om slugtester i berg av Sara Doverfeldt år 2015. Rapport om analys av

It is a method used by hydrogeologists and civil engineers to determine the transmissivity/hydraulic conductivity and storativity of the material the well is completed in The slug test is a commonly used technique for the in situ estimation of hydraulic conductivity at sites of suspected groundwater contamination (Chirlin, 1990; Butler et al., 1996; Butler, 1996). This approach consists of measuring the recovery of head in a well after a near instantaneous change in water level at that well. Schematics of slug test in a monitoring well that is fully screened across a confined aquifer. Slug test is initiated at t = 0; figure not to scale.

• One well field test for determining hydraulic conductivity (K ). • Entails: – “Instantaneously” adding Campbell Scientific PST3 Pump & Slug Test System (up to three wells) The PST3 system (pn 7030) was retired several years ago. It simultaneously A slug test can be performed by causing a sudden rise of the water level (referred to as a falling-head test), or a sudden fall of the water level (referred to as a rising types of information that must be collected prior to slug test analysis in order to obtain reliable aquifer parameter estimates. For example, plausible estimates of help ed. steady Proc. With the slug test the hydraulic conductivity or transmissibility of an aquifer is determined from the rate of rise of the water level in a well His slug test results also compared well to the constant-rate aquifer test.

Capabilities: Import data from data Early slug testing was conducted by quickly adding water to a well or quickly removing a bailer full of water from the well. When environmental monitoring wells PDF | We consider parameters determined by the inversion of slug-test head recovery data with the homogeneous-parameter model of Cooper et al. [1967] to. Oct 3, 1994 When the slug test is performed using an electronic data-logger and pressure transducer, all data will be stored internally or on computer Two of the commonly used solutions to rising-head slug test data. (Hvorslev, 1951; Bouwer & Rice, 1976) treat all of these methods as equivalent, though.
