Fracture-filling hydrate reservoirs have been widely discovered, and electrical properties are typically employed for the characterization of fractured reservoirs. However, usually electrically anisotropic, distribution in fractures will significantly affect anisotropic Therefore, accurate quantification requires to understand effects on We developed a two-step effective medium modeling approach with floating bridging aligned fractures, applied it studying varying fracture parameters...
SUMMARY Fractured hydrate-bearing reservoirs are extensively discovered worldwide and show notable anisotropic geophysical properties. Hydrate distribution in fractures significantly affects the properties, hence plays an important role accurate assessment of hydrate resources. However, knowledge about how impacts properties fractured reservoirs, which is premise for identification quantification still poorly understood. To obtain such knowledge, we forward study effects various (including...
Successful joint inversion of seismic and electromagnetic survey data to estimate parameters improve the characterization earth’s subsurface relies on understanding cross-property relations between elastic electrical properties. Pressure-dependent relationships rocks with varying degrees fluid saturation remain poorly understood even though such conditions are encountered frequently. We investigate this problem by designing undertaking dedicated laboratory experiments simultaneously measure...
Abstract Fractures can widely exist in hydrate‐bearing reservoirs and give rise to anisotropic acoustic properties that play an important role the accurate assessment of fractured reservoirs. However, knowledge responses anisotropy is still poorly understood.

Fractured reservoirs, as one kind of unconventional have great potential for oil and gas development, their accurate characterization requires the development rock-physics models that better simulate real fractured rocks. However, current focus mainly on elastic properties rocks with aligned cracks, while effects randomly orienting cracks in transversely isotropic (TI) are poorly studied even though such conditions frequently encountered earth. To address this problem, we derived a TI...
Overpressure is one of the major difficulties that we have to face when exploring deep earth. Geophysical remote sensing methods, especially seismic and electrical are widely used predict overpressure for derisking drilling boreholes in earth’s crust. However, there uncertainties relating measured geophysical parameters physical properties crustal rocks, needed reliable estimation. We address this knowledge gap through dedicated laboratory measurements elastic velocity, conductivity,...
Geophysical methods detecting electromagnetic properties (e.g., conductivity, relative permittivity, and dielectric loss factor) have been developed into an important tool to accurately assess the hydrate-bearing reservoirs. The key satisfying inversion of collected data is precise understanding responses in However, frequency-dependent anisotropic fracture-filling hydrate reservoirs remain poorly understood. To acquire above understanding, we use a numerical simulation method investigate...
Acoustic properties play an important role in the identification of natural gas hydrate resources, estimation their potential yield and evaluation soil stabilisation during exploration. Physical properties, such as saturation, porosity clay content, are dominant factors that affect acoustic sediments. When considering these modified Biot–Gassmann theory Lee (BGTL), effective-medium (EMT) Frenkel–Gassmann equation (FG) adopted to show characteristics compressional shear wave velocities due...
