Packer Permeability Test. Over 200 packer permeability tests were carried out using several different equipment arrangements to assess the insitu permeability of the geological formations As part of the permeability testing moderately high test pressures were used during packer testing in an attempt to initiate hydrojacking.

The ASTM D463096 Standard Test Method for Determining Transmissivity and Storage Coefficient of Low Permeability Rocks by In Situ Measurements Using the Constant Head Injection Test describes a packer assembly with a flow meter to measure water loss to the formation This information is then used in the calculation of transmissivity storativity and ultimately hydraulic conductivity.

packer test (Lugeon test) Test for measuring the permeability of ground in sections of boreholes An inflatable tube (‘packer’) is lowered down a borehole and expanded so that the sections above and below are isolated Alternatively two packers may be used to isolate a certain section.
Packer permeability testing in deep inclined boreholes
Packer permeability tests are a routine part of ground investigations for construction and tunnelling projects in rock The method described in BS EN ISO 2228232012 (and previously in BS59302010 and earlier editions of the same standard) is used to estimate hydraulic conductivity in rock.

What is Your Packer Test Actually Measuring?
Packer permeability tests are used routinely in geotechnical investigations to allow estimation of hydraulic conductivity by analysis of pressure/flow rate response during controlled injection of water into a section of borehole isolated by packers This paper is a review of the hydraulic fundamentals of the packer permeability test methods and analyses used routinely in geotechnical investigations and discusses the usefulness and limitations of the test Author Martin PreeneCited by Publish Year 2019.
