Friction and compaction data of simulated fault gouges derived from the Basal Zechstein caprock of the Groningen gas field

Luuk Bernd Hunfeld
We investigated the rate-and-state frictional properties of simulated anhydrite-carbonate fault gouge derived from the Basal Zechstein caprock overlying the seismogenic Groningen gas reservoir in the NE Netherlands. Direct shear experiments were performed at in-situ conditions of 50-150 °C and 40 MPa effective normal stress, using sliding velocities of 0.1-10 µm/s. Reservoir pore fluid compositions were simulated using 4.4 Molar NaCl brine, as well as methane, air and brine/gas mixtures. Brine-saturated samples showed friction coefficients (µ)...
