Abstract: To exploit the resource of methane hydrate, it is crucial to understand the mechanical behavior of hydrate-bearing sediments. In this paper an elastoplastic constitutive model is developed for describing the mechanical ...

Abstract: Geomechanical behavior of methane hydrate-bearing sediment (MHBS) plays a major role in evaluation of the stability of a hydrate reservoir. A series of triaxial compression tests were conducted on MHBS to study the influence ...

Abstract: The water retention curve is an important constitutive relation routinely incorporated into numerical stimulations of production from gas hydrate reservoirs. It has significant influences on the physical and mechanical ...

Abstract: In the South China Sea, a significant amount of methane hydrate exists in the sediment containing fine-grained soil. Increasing temperature and/or decreasing pore pressure can remarkably degrade the mechanical characteristics ...
