ABSTRACT
Gas hydrate sediments are a potential energy source due to their high energy content and widespread presence in permafrost and deep-sea regions. This study uses the gas hydrate sediments constitutive model proposed by Wani & Kandasami (2025) to understand the geomechanical response of hydrate sediments. The model introduces a pseudo-consolidation parameter that accounts for the influence of hydrate saturation, pore pressure, and temperature. This parameter is contingent on the distance between the current pore pressure and temperature conditions of the hydrate sediments relative to the stability line. By integrating the dependency of the pseudo-consolidation parameter on this distance, the model accurately predicts geomechanical behavior under varying pore pressures and temperatures, validated against experimental data. A sensitivity analysis of the model parameters is conducted to evaluate their impact, aiding in the calibration of the model. The findings support accurate modeling for safe gas extraction.
