If this is not the case mechanical slug tests may be performed on the well using the transducer, acquisition module and software included with the kit. 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. "Modern slug testing is considerably more rigorous than the typical one-size-fits-all Bouwer and Rice slug tests of old. The FIELD GUIDE FOR SLUG TESTING AND DATA ANALYSIS by the Midwest GeoSciences Group is concise yet technically thorough with just the right amount of detail necessary to guide a user through the critical factors (such as well development) that affect slug testing results 2011-09-28 Slug/bail tests are performed using a single monitor well.

Oct 3, 1994 "A Slug Test for for K calculations. However, it is much more time. Determining the Hydraulic Properties of Tight consuming than the Hvorslev Slug weight. Hydrostatic pressure required to give desired drop inside drill pipe. psi. Difference in pressure gradient between slug and current mud weight.

This research presents a hydraulic conductivity (K) analysis of unconfined aquifers using slug tests. Slug tests are used to determine in situ aquifer hydraulic conductivity more quickly and economically than by a pump test.

slug volume bbls = slug length ft x drill pipe capacity bbl-ft Now that we know how to find the slug calculation in bbls for a Length of DRY Pipe, let’s do an example give the following data. - Desired length of dry pipe, 3 stands = 276 ft

This is a easy chi-square calculator for a contingency table that has up to five rows and five columns (for alternative chi-square calculators, see the column to your right). The calculation takes three steps, allowing you to see how the chi-square statistic is calculated.

The slug test data provided estimates of the hydraulic conductivity of the aquifer immediately adjacent to the boreholes. Pump tests were conducted using downgradient wells in high-hydraulic conductivity zones (based on slug tests) to determine their areas of influence. The tests were analyzed to determine hydraulic conductivity.

This report documents several spreadsheets that have been developed for the analysis of aquifer-pumping test and slug-test data. Each spreadsheet incorporates analytical solution (s) of the partial differential equation for ground-water flow to a well for a specific type of condition or aquifer. During a slug test, a slug of known volume is lowered instantaneously into the well. This is equivalent to an instantaneous addition of water to the well, which results in a sudden rise in the water level in the well (also called a "falling head" test). 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 … 2019-11-18 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.

Hydrostatic pressure required: HP, psi = 12.2ppg x 0.052 x 184ft HP = 117 psi. Continue reading here: Volume height and pressure gained because of slug. Was this article A slug test is a particular type of aquifer test where water is quickly added or removed from a groundwater well, and the change in hydraulic head is monitored through time, to determine the near-well aquifer characteristics. 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.

rejection regions). SlugIn 1.0, a program to Interpret Slug tests, is the answer to the requirement of the Instituto Geológico y Minero de España (IGME) (Spanish Geological Service) for a calculation tool for interpreting permeability tests in boreholes and/or wells Download Limit Exceeded You have exceeded your daily download allowance.

Slug test data obtained from tests performed in an unconfined aquifer are commonly analyzed by graphical or numerical approaches to determine the aquifer parameters. Calculate Hydraulic Conductivity from slugtest data using Bouwer and Rice method. STEP1 - Graph slugtest data - Log Head Vs. Linear Time.

Example Calculation. STEP1 - Graph slugtest data - Log Head Vs. Linear Time. STEP 2 & 3 - Enter test parameters. h 1 = 1.0 ft h 2 = 0.2 ft t 1 = 10 min t 2 = 20 min Well Type: = Partially Penetrating b = 100 ft H = 50 ft L = 15 ft r c = 0.083 ft r w = 0.33 ft

At least one week should elapse between the drilling of a well and the performance of a slug test. Note: For purposes of this document, a bail-down test is a test that instantaneously extracts or withdraws a volume of water or a slug from the well, and a slug test is a test that instantaneously injects a solid slug into the well.

Slug test method. The slug of water can either be added to or removed from the well — the only requirement is that it be done as quickly as possible (the interpretation typically assumes instantaneously), then the water level or pressure is monitored.

Comparison of results from the instream slug tests and empirical calculations showed that Hazen and Harleman equations produced results of K similar to those from the slug tests whereas the Krumbien and Monk and the Kozeny-Carmen equation overestimated the K values of the streambed material.
