# cal simulation of slug tests suggests that KGS is the best method for estimating hydraulic conductivity. At the same time, we can identify a considerable heterogeneity in the area of investigation; indeed, the slug test estimates of hydraulic conductivity (K) range over three orders of …

Slug/bail tests are performed using a single monitor well. Pumping and observation wells are not required for the test. Analysis of slug/bail test data is also very straightforward. On some occasions, slug/bail tests are an alternative testing method to the aquifer test described in the next section.

Find the hydrostatic pressure it takes to create a specific drop inside of the drill pipe. We can find this by using the following formula: HP psi = Mud Weight ppg x 0.052 x length of DRY pipe in feet. Step 2 -. Overdamped slug tests A mathematical solution by Hvorslev (1951)is useful for determining the hydraulic conductivity (K) of nonleaky confinedaquifers.

Calculation No.: U0174200. 1.0 Introduction. Aquifer and slug tests were completed at the Green River Uranium Mill Tailings Remedial Action (UMTRA) Project site to collect the hydrogeologic data necessary to characterize the Browns Wash alluvial aquifer and the middle sandstone unit of the Cedar Mountain Formation. Slug test data obtained from tests performed in an unconfined aquifer are commonly analyzed by graphical or numerical approaches to determine the aquifer parameters.

From these data, an estimate of hydraulic conduc-tivity can be calculated using appropriate analytical methods (for example, Ferris and Knowles, 1963).

## This webinar discusses using slug tests to evaluate an aquifer. Learn what slug tests are and why they are conducted, the differences between solid slug test

Slug catcher sizing is a function of many things including the various operating cases and flows and crtically the liquid pump out or flow out flow rate from the slug catcher. Pigging will give you a big volume, but the usual get -out is to pig at a much lower gas flow rate when pigging and reduce pig velocity to 2-3 m/sec, hence reducing your liquid flow rate into the slug catcher.

First Stage : Find hydrostatic pressure to create a specific drop inside of the Drill Pipe. Formula: HP psi = Mud Weight ppg * 0.052 * length of DRY pipe in feet 2019-08-25 In general, the test is conducted by adding (or removing) a slug to raise (or lower) the water level from its original equilibrium level, and measuring the rate of water level recovery. Other means of displacing the water column, such as compressed air, are equally amenable to analysis by these methods. Spreadsheets for the Analysis of Aquifer-Test and Slug-Test Data, Version 1.2.
