Description
The LP-700 determines rock sample permeability using the steady-state method in accordance with Darcy’s Law. The unit includes all components necessary to carry out a permeability test. It is equipped with two pressure transducers to measure upstream and downstream pressures, two differential pressure transducers to measure the pressure drop across the sample: a low-range sensor for high-permeability specimens and a high-range sensor for low-permeability specimens. A controlled flow of pore fluid is injected through the core using a pore-pressure pump to determine permeability. The sample is enclosed in a jacket, placed inside an overburden cell, and subjected to the required confining pressure. Fluid is introduced at the inlet face, while a back-pressure regulator maintains a constant outlet pressure to ensure stable test conditions. The BPR features its own pressure-setting system, allowing the pore pressure to be adjusted to the desired value.
