Permeability data for micro- and macrocracked Lanhélin granite samples measured at elevated pressure and temperature

Text files contain raw data obtained during permeability measurements on micro cracked granite samples using either a steady-state method (indicated as SS in the file name) or a pulse decay method (indicated as P in the file name). The recorded variables include Time (in seconds), Flowrate (in mln/min) and Differential pressure (in mbar).Excel files contain raw data obtained during permeability measurements on micro- and macrocracked samples using a steady-state method. They also serve directly as spreadsheets for the derivation of permeability and the corrections for fluid-flow related artefacts (Forchheimer and Klinkenberg effects) and temperature effects.
