Numerical Modeling of Permeability Enhancement and Induced Seismicity during EGS Operation using a Partially Bridging Multi-stage Hydraulic Fracture design

open access: yes, 2023
Enhanced geothermal systems (EGS) have emerged as an alternative energy supply that is both green and tackles climate change. Multi-stage hydraulic fractured horizontal well design is a promising design for economic EGS development. In our previous work,

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds

open access: yesThe Journal of Wildlife Management, EarlyView.
Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Seismicity and development of Romashkino hydrocarbon field’s Almetyevskaya area

open access: yesGeoresursy
The relationship between the various human activities and seismic activity has become more evident in the last several decades. One of the important domains where such a relationship manifests itself is hydrocarbon fields’ development.

A Passive Low‐Frequency, High‐Sensitivity Diamagnetic Levitation Accelerometer

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Despite the great potential of diamagnetic levitation accelerometers in detecting low‐frequency and weak motion, there is still a demand to further enhance their sensitivity for geophysical and microgravity applications. In this study, a straightforward structural modulating approach is presented to enhance the sensitivity of diamagnetic ...

A Coupled Extended Finite Element–Cohesive Zone Model for Hydraulic Fracture Propagation Under Poroelastic Effects Across Different Propagation Regimes

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.
