A new triaxial apparatus to study the mechanical and fluid flow aspects of carbon dioxide sequestration in geological formations

► Triaxial apparatus for high confining and injection pressures for CO2 sequestration. ► To conduct mechanical and permeability tests on intact or fractured rock samples. ► Delivering fluids at up to 50 MPa injecting and 70 MPa confining pressures. ► Record injection and confining pressures, axial load and displacement and outflow rates. ► Leakage and sample tests have confirmed the effectiveness of the device.
