Injection-induced seismicity has become one of the most critical challenges for widespread deployment Enhanced Geothermal Systems (EGS). In particular, some EGS development projects have led to large, damaging earthquakes that unexpectedly occurred far off stimulated reservoir region and, in after stopping fluid injection. Yet, causative mechanisms these patterns remain highly elusive. Here, we identify a combination could explain delayed sites by conducting fully-coupled hydromechanical...
Abstract Deep geothermal energy (DGE) represents an opportunity for a sustainable and carbon-free supply. One of the main concerns DGE is induced seismicity that may produce damaging earthquakes, challenging its widespread exploitation. It widely believed risk can be controlled by using doublet systems circulating water to minimize injection-induced pressure changes. However, cold reinjection also give rise thermal stresses within beyond cooled region, whose potential impacts on fault...
Abstract. Fluid injection into geological formations for energy resource development frequently induces (micro)seismicity. Moderate- to large-magnitude induced earthquakes may cause injuries and/or economic loss, with the consequence of jeopardizing operation and future these geo-energy projects. To achieve an improved understanding mechanisms seismicity, develop forecasting tools manage associated risks, it is necessary carefully examine seismic data from reported cases seismicity...
Porosity, pore structure characteristics, and permeability are among the key petrophysical properties of shale gas resources. Accurate characterization these parameters in unconventional systems has been proved to be challenging due uniqueness structures, mineral compositions, tightness, pores hosted organic matter. In this study, porosity, cored samples from Garau formation located southwestern part Iran were evaluated using a combination laboratory methods. Multiple linear regression...
Abstract Geologic carbon storage in deep saline aquifers has emerged as a promising technique to mitigate climate change. CO 2 is buoyant at the conditions and tends float over resident brine jeopardizing long-term containment goals. Therefore, caprock sealing capacity of great importance requires detailed assessment. We perform supercritical injection experiments on shaly samples (intact fault zone) under representative subsurface conditions. numerically simulate experiments, satisfactorily...
Energy systems models analyzed by the UN Intergovernmental Panel on Climate Change (IPCC) suggest that geologic carbon storage (GCS) at annual rates of several gigatonnes may be required to effectively mitigate climate change crisis. Deployment GCS such large scales needs address uncertainties about availability and use subsurface resources. A major concern is growing risk induced seismicity with scale implementation as wastewater disposal comparable led a surge in seismic activity central...
Geochemical reactions in porous rocks are typically scaled up using effective reaction parameters derived under well-mixed conditions. Such conditions often absent natural settings. While conventional transport theories based fundamentally on diffusion and dispersion processes can not fully capture the state of mixing, several lines evidence point to dominance chaotic solute mixing. Yet, proving existence mixing remains unresolved mostly due limitations directly observing pore-scale...
Induced seismicity is likely a major obstacle in front of the widespread deployment geoenergy applications, such as geothermal energy or geologic carbon storage (GCS), which are indispensable components efforts to mitigate climate change emergency. earthquakes may jeopardize integrity subsurface structures and, if felt at surface, negatively impact public perception projects. Thus, effective and safe use provide clean sustainable reduce atmospheric emissions needs properly address risks...
Abstract The effectiveness of Carbon Capture and Storage (CCS) as an imperative decarbonization technology relies on the sealing capacity a fine‐grained caprock to permanently store CO 2 deep underground. Uncertainties in assessing increase with spatial temporal scales may delay CCS deployment at gigatonne scale. We have developed computationally efficient transport model capture dynamics basin‐wide upward migration multi‐layered setting over geological time scales. find that massive...
Reservoir-triggered seismicity commonly occurs as a result of reservoir impoundment. In particular, the Nova Ponte triggered series earthquakes, including 1998 M4.0 earthquake, which represents second-largest earthquake by impoundment in Brazil. The occurred after prolonged seismic activity following starting 1993. After more than two decades, mechanisms governing these earthquakes and their relation with spatiotemporal evolution events are still poorly understood. Here, we explain causal...

In the current study, two approaches were adopted predict shear velocities several petrophysical well logs, including gamma ray (GR), density (RHOB), neutron (NPHI), compressional (Vp). For this purpose, five intelligent models random forest (RF), extra tree (ET), Gaussian process regression (GPR), integration adaptive neuro fuzzy inference system...
Miscible gas injection has been considered one of the most important enhanced oil recovery techniques. Minimum miscibility pressure (MMP) is a key parameter in design an efficient miscible project.

Abstract Guaranteeing the sealing capacity of caprocks becomes paramount as CO 2 storage scales up to gigaton scale. A significant number laboratory experiments have been performed with samples intact rock, showing that low-permeability and high-entry pressure excellent capacities contain deep underground. However, discontinuities, such bedding planes, fractures faults, affect rock properties at field scale, being same time challenging monitor in industrial-scale applications. To bridge...
