The Change in Geomechanical Properties of Gas Saturated Methane Hydrate‐Bearing Sand Resulting From Water Saturation

Abstract: Laboratory tests were carried out on gas‐saturated hydrate‐bearing sand (HBS) specimens that were subsequently water saturated to determine the influence of water saturation on their small‐strain (stiffness) and large‐strain (strength) behavior. Hydrate formed using the “excess gas” method led to significant increases in stiffness and strength of the sand. The magnitude increase in stiffness was largest for the lowest hydrate saturation tests and was sensitive to the distribution of hydrate within the sand. In… Show more

“…Waite et al [73] provide a comprehensive pre-2009 review of research investigating solubility and formation considerations, thermal properties, fluid migration, EM properties, and seismic wave speeds of hydrate-bearing sediments. A selection of more recent investigations on mechanical properties and water saturation effects includes [74][75][76][77][78], a mere fraction of the work on this broad topic. In many cases, THF hydrate is used in experiments as it is stable under easily accessible temperature and pressure conditions and can be formed over short laboratory timescales.…”
