| The concept of this test lies in the measurement of the volume of water that can escape from an uncased section of a borehole in a given time under a given pressure. Flow is confined between known depths by means of packers. The flow is confined between two packers in a double packer, or between one packer and the bottom of a hole in a single packer. In other words this test measures the acceptance of water under pressure by in-situ rock, to determine the permeability and Lugeon value. |
