Subsurface leakage of fluids, such as CO 2 , along faults is a key quantity to estimate when modeling underground fluid storage. Using our coupled multiphase flow-geomechanics-fault slip simulator, we quantify leakage dynamics using the fault dip angle and leakage magnitude, a proposed metric of gas leakage. We present novel leakage dynamics of faults to show that leakage is non-trivially coupled to induced seismicity and multiphase flow along faults due to the effect of fault dip. The onset time of induced fault slip, controlled by the initial shearto-effective normal stress ratio on the fault, is a non-monotonic function of the fault dip. The leakage directions of gas and liquid phases are determined by the directions of slip propagation and the buoyancy vector, both of which depend on the dip. A consequence is that leakage evolution is non-monotonic in time for hanging wall injection-induced seismicity on a normal fault because of the competition between up-dip oriented buoyancy and down-dip oriented induced slip. With respect to monitoring, we note that subsidence at the location of an injection well could be indicative of leakage. K E Y W O R D Sfault leakage, induced seismicity, underground gas storage INTRODUCTIONInjection and storage of fluids in underground aquifers is important for many industrial applications. Natural gas is stored underground during summer months and produced during winter months to meet the seasonal demand of heating gas. 1,2 Radioactive waste 3,4 and wastewater 5-8 are candidates for injection underground for long-term disposal. CO 2 is injected underground as part of Carbon Capture and Sequestration (CCS) and enhanced oil recovery projects. [9][10][11][12][13][14][15][16] Underground storage is also a naturally occurring process for example, during creation of petroleum reservoirs in structural traps. 17 Injection-induced stresses can cause ground deformation [18][19][20][21][22][23] and induce shear and tensile failures along faults and fractures, [24][25][26][27][28][29][30] which are ubiquitous in the subsurface. Fault slip is often associated with changes in permeability that can lead to flow of stored fluids up-dip or down-dip along a fault and consequently leakage into shallower or deeper formations, respectively. 4,[31][32][33][34] Leakage can cause contamination of underground sources of drinking water 35,36 and pose health and environmental risks on the ground surface. 37 In case of CO 2 storage, unless below a leakage limit, 38 even a small leakage flux can result into a significant loss of volume over the hundred-year time scale of such projects. Such concerns have fueled research in monitoring of leakage via various means for example, geochemical, 39,40 hydrological, 20,41-43 geophysical, 44,45 electrical, [45][46][47] and isotopic. 48,49

The geological storage of carbon dioxide is considered as one of the measures to reduce greenhouse gas emissions and to mitigate global warming. Operators of storage sites are required to demonstrate safe containment and stable behaviour of the storage complex that is achieved by geophysical and geochemical monitoring, combined with reservoir simulations. For site characterization, as well as for imaging the carbon dioxide plume in the reservoir complex and detecting potential leakage, surface and surface‐borehole time‐lapse seismic monitoring surveys are the most widespread and established tools. At the Ketzin pilot site for carbon dioxide storage, permanently installed fibre‐optic cables, initially deployed for distributed temperature sensing, were used as seismic receiver arrays, demonstrating their ability to provide high‐resolution images of the storage formation. A vertical seismic profiling experiment was acquired using 23 source point locations and the daisy‐chained deployment of a fibre‐optic cable in four wells as a receiver array. The data were used to generate a 3D vertical seismic profiling cube, complementing the large‐scale 3D surface seismic measurements by a high resolution image of the reservoir close to the injection well. Stacking long vibro‐sweeps at each source location resulted in vertical seismic profiling shot gathers characterized by a signal‐to‐noise ratio similar to gathers acquired using geophones. A detailed data analysis shows strong dependency of data quality on borehole conditions with significantly better signal‐to‐noise ratio in regions with good coupling conditions.
