Natural gas hydrate deposits (NGHD) have been investigated for decades and represent
one of the major methane reservoirs on Earth. They are encountered in sediment of both the …

Fracture-filling hydrate constitutes a pivotal component within the global hydrate reserves
and serve as a significant focal point for hydrate exploration and development. However, the …

Natural gas hydrates are crystalline solids found in sediments beneath the seabed and
permafrost, which significantly affect the mechanical behavior of sediments. The effect of …

Due to the extremely complex reservoirs and strong heterogeneity, deep-sea gas hydrate
logging porosity calculations still have problems, which further leads to insufficient resource …

Quantitative characterization of hydrate reservoirs is essential for evaluating hydrate
resources and monitoring environmental hazards. Rock-physics models provide the …

Numerous models have been developed for prediction of gas hydrate saturation based on
the microstructural relationship between gas hydrates and sediment grains. However …

Natural gas hydrates have the properties of ice with a microporous structure and its
concentration in sediments highly affects the wave velocity and attenuation. Previous studies …

In this paper, the dynamic and static elastic properties of cement pastes with a large range of
water to cement (w/c) ratios were modeled for the whole hydration range from 0 to 1. A …

Rock-physics modeling of hydrate reservoirs is an efficacious solution for assessing the
macroscopic elastic responses of rocks induced by microphysical parameters, pore …

The Extreme gradient boosting algorithm XGBoost has been confirmed to be an accurate
method for predicting rock stiffnesses and anisotropic parameters from basic input features …
