Data logger for Lugeon Test : the Lugeon test allows you to assess the permeability or billing of rock formations.
In fact this test gets its name from Maurice Lugeon (1933), a Swiss geologist who first formulated the test.
Accordingly this test is also known as “water pressure test” or “packer test”.
Firstly it can be carried out during the advance of the drilling, using only one packer or with a complete hole by means of a pair of packers.
In other words it is a water injection test through the drilling of rock masses that have a certain mechanical strength.
Therefore the procedure for carrying out the test is to enter water under pressure into boreholes.
Besides in the boreholes a pipe for water supply is lowered with two shutters that allow to isolate the stretch of hole in which the test is to be carried out.
Again the tests are carried out for at least 5 values of the injection pressure, each kept constant for 10, 20 minutes.
In addition to this, it is possible to perform tests in advance, stopping the drilling every 2 – 5 meters, or in ascent when drilling is finished.
Obviously, the measured permeability is expressed in Lugeon Unit, where 1 Lugeon corresponds to the permeability of a rock formation that absorbs about 1 liter of water per minute, per meter, at a pressure of 10 atmospheres.
