Slug test vs pump test

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. Slug and pumping tests are used to determine in-situ properties of water-bearing formations and define the overall hydrogeologic regime. Such tests can determine transmissivity (T), hydraulic conductivity (K), Slug tests only sample a small region around the well and may be more representative of the disturbance of well installation or development than in situ conductivity. To provide a larger scale comparison to slug test estimates of hydraulic conductivity for unweathered Wisconsin age till in Iowa, a pumping test was performed, with both the pumping and monitoring wells placed in unweathered till.

Comparison of constant-rate pumping test and slug interference test results at the Hanford Site B pond multilevel test facility A pumping test does not require expensive large-diameter wells. If a suction pump placed on the ground surface is used, as in shallow watertable areas, the diameter of the well can be small. A submersible pump requires a well diameter large enough to accommodate the pump.

Pumpvolymen justeras med målsättning att hitta en jämviktssituation där pumpningen och tillrinningen är lika stor. Slugtest (in – och utströmningsförsök). Slugtest används vanligtvis för beräkning av jordens hydrauliska konduktivitet, och är egentligen ett förenklat pumpförsök. I vissa rör utfördes hydraultest vilka redovisas i följande avsnitt.

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. For a given slug test, select a method of initiation that introduces minimal noise into water-level readings. Slug tests may be initiated in a number of ways including the following methods: solid slug; bailer; pneumatic pressurization (1998) conducted slug test in wells with partially submerged screens.

Technical data of the groundwater monitoring wells. The slug test data provided estimates of the hydraulic conductivity of the aquifer immediately adjacent to the boreholes.

Analysis of slug-tests with high-frequency oscillations by Olivier Audouin 1,2,3 and Jacques Bodin 1,2 1Université de Poitiers, FRE 3114 HydrASA, 40 av .Recteur Pineau, 86022 Poitiers Cedex, France 2CNRS/INSU, FRE 3114 HydrASA, 40 av. Recteu r Pineau, 86022 Poitiers Cedex, France 3Now at SEMM LOGGING, Les Maufras, 18360 Vesdun, France Abstract The Slug Test Method is one of a number of different methods that are used to evaluate the permeability (or hydraulic conductivity) of an aquifer. The procedure involves either adding or removi ng a measured quantity of water from a well rapidly, followed by making a rapid series of water-level measurements to assess the rate of water-level recovery (either rising-head or falling-head). 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.
