Investigating fracture network creation and stimulation mechanism of EGS reservoirs

Ayaka Abe et al.

Summary: Based on previous EGS projects, hydraulic stimulation can create a complex fracture network consisting of preexisting fractures and newly formed fractures. To further understand hydraulic stimulation mechanisms in an actual EGS reservoir, a numerical model was applied to investigate the interaction between a preexisting fracture and a newly formed fracture in Fenton Hill Phase-2 reservoir and Basel EGS site. The results indicate that the Fenton Hill setting generated a broad fracture network with branching flow paths, while the Basel setting produced a narrow fracture network with straight flow paths. This study suggests that the dimensions, migration orientation, and complexity of a fracture network are influenced by preexisting fractures' stress state, dominant orientation, and initial connectivity. Furthermore, stimulating a reservoir with poorly-oriented preexisting fractures may result in a complex and broad fracture network, which is advantageous for energy recovery.

Fault strength and rupture process controlled by fault surface topography

Shiqing Xu et al.

Summary: The topographic heterogeneity of faults affects their strength and earthquake properties. Less heterogeneous faults are weaker and have a larger stress drop compared to more heterogeneous faults. Rupture along less heterogeneous faults tends to propagate at subshear speed while more heterogeneous faults accommodate a wider range of rupture speeds. These findings have implications for understanding natural faults and earthquakes.

Modelling of fluid pressure migration in a pressure sensitive fault zone subject to cyclic injection and implications for injection-induced seismicity

Yinlin Ji et al.

Summary: Fault zones are major fluid pathways in geo-energy systems, but injection-induced instability can cause large earthquakes. Cyclic injection is proposed as an alternative protocol to mitigate seismic risks. The extent and magnitude of fluid pressure perturbation determine the risks of injection-induced seismicity.

Fault roughness controls sliding instability

Doron Morad et al.

Summary: The frictional strength of faults plays a crucial role in controlling the stability and dynamics of slip in natural phenomena such as earthquakes, induced seismicity, and landslides. This study demonstrates experimentally how slip dynamics vary dramatically with surface roughness, with stick-slip oscillations occurring only within a specific range of roughness values defined as the critical roughness. The findings highlight the importance of dilatant shear across moderately rough interfaces for inducing stick slip oscillations and sliding instability.

Laboratory experiments on fault behavior towards better understanding of injection-induced seismicity in geoenergy systems

Yinlin Ji et al.

Summary: Induced seismicity from fluid injection into underground formations poses a threat to sustainable utilization of the subsurface. Laboratory experiments have played a crucial role in understanding the fault behavior related to injection-induced seismicity. This review provides an overview of the current understanding of injection-induced seismicity from the laboratory perspective. It covers the basics of fault behavior, laboratory methods, and the effects of various factors on fault behavior, with a focus on implications for injection-induced seismicity. The review highlights the advancements made in understanding the role of fault properties, stress state, fluid physics, and injection protocol in injection-induced seismicity. However, there are still unresolved questions that could be addressed in future experimental studies.

Transient evolution of permeability and friction in a slowly slipping fault activated by fluid pressurization

Frederic Cappa et al.

Summary: This study investigates the mechanisms of permeability and friction evolution in a natural fault in situ. The authors conclude that the transient evolution of fault permeability and friction caused by a pressure perturbation exerts a potentially dominant control on fault stability during fluid flow.

Fluid migration in low-permeability faults driven by decoupling of fault slip and opening

Frederic Cappa et al.

Summary: The decoupling of fault slip and opening drives rapid fluid pressurization and migration in low-permeability faults, with fault displacement occurring before the build-up of fluid pressure. Once fluid migration occurs due to slip-induced permeability increase, the fault experiences further opening.

Cyclic Water Injection Potentially Mitigates Seismic Risks by Promoting Slow and Stable Slip of a Natural Fracture in Granite

Yinlin Ji et al.

Summary: The study investigates the activation of a critically stressed natural fracture in granite under pressure-controlled and volume-controlled monotonic and cyclic water injection. Results show that cyclic injection can lead to aseismic fracture slip at smaller peak slip rates compared to monotonic injection, but continued injection after an unstable shut-in stage could result in rapid and unstable fracture slip.

More Than 40 yr of Potentially Induced Seismicity Close to the San Andreas Fault in San Ardo, Central California

Thomas H. W. Goebel et al.

Summary: Fluid-injection-induced seismicity is rare in California hydrocarbon basins where evidence shows surface deformation in San Ardo oilfield, potential seismicity associated with injection, and correlations between seismicity and wastewater disposal wells. The seismic behavior at San Ardo is complex with clustering of earthquakes occurring at close spatial proximity but long interevent times, suggesting multiple processes contribute to potentially induced earthquakes. It is observed that fluid-injection operations occur close to seismically active faults in California, yet seismicity is predominantly observed on smaller unmapped faults with little evidence that large faults are sensitive to induced stress changes.
