CRIEPI has performed several conservative tracer tests to characterise the target fractures at depth. Newly developed equipment which can treat both sorbing and conservative tracers was demonstrated at the C-FRS site. A highly viscous fluid was injected to obtain more information about the flow dimension and aperture of the target fractures.
