Diffusive transport of chloride into and out of soil-cement mixtures

This study investigates the diffusive transport behaviour of chloride in cement-based solidified/stabilised (s/s) soil mixtures, focusing on the differences between inward diffusion (into previously uncontaminated specimens) and outward diffusion (from pre-mixed specimens). Two s...

2D and 3D Geomechanical Numerical Simulation for Evaluating Well-Stability and Reservoir Consolidation during the Production from the HYDRATE P1 Well on the Alaska North Slope

Abstract Methane hydrate production via depressurization can induce geomechanical changes in hydrate-bearing sediments, thereby impacting production performance and risking subsidence and wellbore instability. Here, a fully coupled thermo-hydro-mechanical simulator (COTHMA) is ap...
