AutoLab 1000

AutoLab 1000 is a hydrostatic servo-hydraulic system for measurements of compressional and shear wave velocities, permeability, electrical resistivity, pore volume compressibility, and linear compressibility on rock specimens up to 50 mm (2.0 in) in diameter at in situ overburden pressure, pore pressure, and temperature. The high-pressure system consists of a pressure vessel and servo-hydraulic intensifiers for confining and pore pressure. Coreholders for velocity, permeability, and resistivity are mounted on cloverleaf closures that are inserted in the pressure vessel and locked with a 60° rotation. This design is convenient for routine measurements at reservoir pressures up to 100 MPa (15,000 psi) and temperature. An external furnace heats the vessel.
