Numerical simulation of injection-induced seismicity

, 2022
Geo-energies, such as geothermal energy, geologic carbon storage, and subsurface energy storage, will play a relevant role in reaching carbon neutrality and allowing net-carbon removal towards the midcentury.

Probabilistic prediction of rate‐dependent rock strength using natural gradient boosting and Gaussian process regression

Deep Underground Science and Engineering, EarlyView.
Probabilistic natural gradient boosting and Gaussian process regression models accurately predict rate‐dependent rock strength across lithologies. Static strength and strain rate dominate, while geometric factors have minimal influence, enabling interpretable and uncertainty‐aware predictions for dynamic geomechanical applications. Abstract The dynamic

MULTISCALE SPATIOTEMPORAL ANALYSES OF SEISMICITY AND WASTEWATER INJECTION IN OKLAHOMA [PDF]

, 2017
The increase in seismicity in Oklahoma since 2009 has been primarily attributed to wastewater disposal, however, the extent and nature of the relationship is not clear.

Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

Deep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Reservoir Stimulation's Effect on Depletion‐Induced Seismicity

, 2018
International audienceDepletion‐induced seismicity can pose a problem in some fluid‐producing subsurface reservoirs, in some cases requiring production rate control in order to limit the seismicity.

Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Whole-mine subsidence over tabular deposits and related seismicity

International Journal of Mining Science and Technology, 2017
The challenge of estimating mine-wide subsidence and linkages to seismicity over tabular deposits is addressed by a special finite element technique (dual node–dual mesh). Subsidence and mine-induced seismicity begins near the face when caving occurs and
