In addition to the injection of water-soluble polymer the injection of surfactants has been recognised since the 1970s (Healy...

... co- hydrate, the effect of hydrate saturation should be taken into executions. consideration. Actually, the hydrate has a cement liked effect in enhancing the total strength of hydrate sediment (Sánchez et al., 2017). 1. Model approach When it dissociates into water and gas, there are two impacts...

... are filled in the pores of rock particles, different saturation and porosity constitute different media. Therefore, the outdoor cryogenic sound wave measurement experiment scheme is used. Under the experimental conditions of low temperature, the influence of gas hydrates with different saturation...

... ABSTRACT Cracks may be created in clays after gas hydrate dissociates. More cracks can be created in clays with a high degree of gas saturation after dissociation and the degree of gas saturation is linked to peak undrained shear strength of the clays through experimental tests. A damage model...
