Product DescriptionThe Lugeon test, sometimes call also Packer
test, is an in-situ testing method widely used to estimate the
avarage hydraulic conductivity of rock mass. It is indeed In situ
test of formation permeability performed by measuring the volume of
water taken in a section of test hole when the interval is
pressurized at given pressure (10 bars -150 psi). It is used
primarily in variably permeable formations under evaluation of
fracturating .Deployment and operation is simple. The wireline
permeability packer assemble is deployed down the drill rods until
the bit seating sub lands on the drill rod bit. With the top seal
assembly (tighthead) tightened, the packers are inflated and water
is then pumped through the tighthead down the rods, through the
packers and into the formation. Product ParametersMain
