Efficient analysis of problems in geomechanics
Ways of combining the Finite and Boundary Element Methods for the analysis of geomechanics problems are investigated. Examples for two approaches are presented and an assessment of the effort required both in programming and data preparation is given ...

Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

Real – Time Geomechanics: Applications to Deepwater Drilling
Lithologies under deepwater conditions usually show relatively reduced effective stress, due to the reduced lithostatic column. This translates into relatively narrow mud weight windows, driven mainly by shear failure or pore pressure in overpressured ...

Analytical Methodology to Determine Thermally Induced Soil Deformation From Laboratory Data
ABSTRACT Experimental laboratory investigations underlie most of the knowledge about the mechanics of soils under non‐isothermal conditions and their thermally induced deformation. Despite advances, the understanding of thermally induced deformation of soils remains inconsistent, hindering the development of a coherent framework that can advance ...

Numerical Modeling of Geothermal Heat and Lithium Co‐Production in Fault‐Hosted Reservoirs
Abstract The global transition to low‐carbon energy systems is driving demand for lithium, a critical raw material for battery storage technologies. Geothermal brines, particularly in the Upper Rhine Graben (URG) in western Europe, offer a potential lithium source co‐produced with heat, providing economic and strategic benefits.

Salt Tectonics and Inversion Style in the Southeastern Iberian Chain
Abstract The southeastern Iberian Chain is characterized by Mesozoic rift basins that were subsequently inverted during Alpine contraction. We integrate geological mapping, borehole data, balanced cross‐sections, structural restoration, and forward kinematic modeling to evaluate how rift architecture controlled Alpine deformation from basin to crustal ...

Magnitudes and Rates of Strength‐Drawdown Modulate Injection‐Induced Seismicity
Abstract Accurately forecasting injection‐induced seismicity remains a major challenge that is critically important for energy production and storage as controlling mechanisms are complex and remain opaque. We clarify key processes by following time‐histories of bespoke parameters anticipated to control strength reduction (drawdown) through ...

Micromechanical Insights Into the Cyclic Behavior of Fault‐Valve Systems
Abstract Cyclic fluid pressurization can promote repeated fault reactivation and transient permeability changes, a behavior often discussed within the fault‐valve concept in which faults alternate between acting as hydraulic barriers and conduits. To investigate the micromechanical processes involved during fluid induced reactivations, we simulate ...
