Description
FLECAS-HT is a unique flow-through system enabling the simultaneous measurement of permeability and electrical resistivity (co-axial 4-electrode arrangement) on rock cylinders with a diameter of 30 mm and a length of 75 mm at temperatures of up to 500 °C. Currently, FLECAS-HT can be operated at a maximum confining Ar-gas pressure of 40 MPa, and a pore fluid pressure of 25 MPa. Due to the corrosive nature of high enthalpy aqueous fluids, the sample must be encapsulated with a gold tube.
Scientific topics:
- Long-term flow-through experiments (weeks to months) at simulated reservoir conditions
- Effect of chemical fluid-rock interactions on hydraulic and electrical rock properties
- Effect of phase transitions (liquid solid/ liquid gas) on physical rock properties
