FLECAS was designed as versatile and transportable core analysis system for the investigation of consolidated and unconsolidated rocks under reservoir temperature and pressure conditions. It comprises a measuring setup for the measurement of porosity, permeability, electrical resistivity, ultrasonic compressional and shear wave velocities and amplitudes.
The system was applied for
 

• the study of gas hydrate bearing sediments in the frame of the Mallik 2002 gas hydrate production research well program at the Mallik field laboratory at Inuvik, NWT, Canada,
• investigations at temperatures up to 250 °C of water saturated volcanic rocks from Icelandic high - temperature geothermal reservoirs,
• injection experiments of supercritical CO2 into potential host rocks and cap rocks of CO2 sequestration sites.

A similar system is currently assembled which permits long term constant flow experiments at conditions that can be found in the reservoir of the in-situ geothermal lab Groß Schönebeck.
