Robotic Arm Geomechanical Experiments and Analyses to Enable Lunar Science and Settlement

Earth and Space Science
This study evaluates the capability of a robotic arm equipped with a force‐torque sensor and a specially designed scoop to perform geomechanical characterization of high‐fidelity lunar highlands regolith simulant. Experiments focused on pressure‐sinkage,

Anomalous Pressure Diffusion and Deformation in Two‐ and Three‐Dimensional Heterogeneous Fractured Media

Water Resources Research
In fractured and stress‐sensitive reservoirs and aquifers, hydromechanical coupling is important, in connection with their heat and solute transport properties, and because the fluid production or extraction leads to land subsidence and potentially to ...

Impact of hydraulic fracturing on a nearby well under drilling

Известия высших учебных заведений: Нефть и газ
The premise of the study is increasing cases of negative impacts of hydraulic fracturing on nearby wells that are still being drilled, especially in areas with dense well clustering and abnormally high reservoir pressure.
