Abstract

The In Salah Joint Venture carbon capture and storage project at Krechba, Algeria began injecting CO2 in 2004. This study makes use of microseismic event data recorded by a single geophone. Information from shear waves enables fracture directions and densities to be inferred and we find fractures striking N145°E, in agreement with the regional direction of maximum horizontal stress. There is no evidence for any temporal change in shear-wave splitting parameters in the time frame studied. This implies that CO2 injection is reactivating pre-existing fractures. We are able to obtain only very approximate event locations which suggest that events occur at or below the reservoir level, with no change over time.
