Combination of CO 2 ${\text{CO}}_{2}$ storage and geothermal energy production in porous and fractured superhot geothermal systems

Deep Underground Science and Engineering, EarlyView.
The graphical abstract depicts the workflow for porous‐ and fractured‐media simulations, where stochastically generated discrete natural fractures are required for the fracture‐media simulation. Abstract CO 2 ${\text{CO}}_{2}$ leakage is one of the main risks and barriers to geologic carbon storage. However, under the high‐temperature and high‐pressure

Multi‐factor coupling effects in hydraulic fracturing of laminated shale: Experimental insights and physics‐informed neural network‐driven optimization

Deep Underground Science and Engineering, EarlyView.
This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Geological carbon dioxide storage in the German North Sea: Static‐to‐dynamic capacity refinement for a 10 Mt/y injection scenario

Deep Underground Science and Engineering, EarlyView.
This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Large-Time Behavior of Solutions to Darcy–Boussinesq Equations with Non-Vanishing Scalar Acceleration Coefficient

Mathematics
We study the large-time behavior of solutions to Darcy–Boussinesq equations with a non-vanishing scalar acceleration coefficient, which model buoyancy-driven flows in porous media with spatially varying gravity.

Numerical investigation of natural fracture activation and leakage risk during CO2 sequestration in depleted sandstone reservoirs

Deep Underground Science and Engineering, EarlyView.
This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

Analysis of film condensation on a vertical plate embedded in porous media under local thermal non-equilibrium condition

Case Studies in Thermal Engineering
Film condensation on a vertical plate embedded in porous media under the local thermal non-equilibrium (LTNE) condition is analyzed. The Darcy-Brinkman model and the LTNE model are introduced to establish the mathematical formulation.
