Abstract Understanding the adsorption mechanisms of CO 2 and N in illite, one main components clay shale, is important to improve precision shale gas exploration development. We investigated K-illite with varying pore sizes at temperature 333, 363 393 K over a broad range pressures up 30 MPa using grand canonical Monte Carlo (GCMC) simulation method. The system proved be reasonable suitable through discussion impact cation dynamics wall thickness. results excess amount, expressed per unit...
Abstract Seismic characterization of fractures is great importance in many disciplines, for which rock physics models provide the basis to link fracture properties seismic attributes. However, date, most neglect background anisotropy that may exist fractured formations. Hence, this work, we developed a theoretical model effective elastic with penny‐shaped cracks embedded transversely isotropic (TI) medium. We first derived analytical solutions case dry or fluid‐filled parallel plane TI...
Abstract Classical third‐order thermoelastic constants are generally derived from the theory of small‐amplitude acoustic waves in isotropic materials during heat treatments. Investigating higher‐order for higher temperatures is challenging owing to involvement number unknown parameters. These Taylor‐type classical thermoelasticity formulated based on Taylor series Helmholtz free energy density preheated crystals. However, these models limited even at low characterizing temperature‐dependent...

Differential effective medium (DEM) models to interpret seismic survey data with greatest success. However, cementation exponent pore aspect ratio as indispensable geometric parameters in elastic DEM independent, making not suitable joint elastic-electrical modelling, a key requirement interpretation of better understand increasingly complex hydrocarbon...

Joint interpretation of seismic and electrical survey data can help to better characterize the subsurface. However, key successful joint is understand correlations between elastic properties (i.e., elastic-electrical properties) underground rocks. This work aims investigate effects temperature on porous rocks by simultaneously measuring P-wave velocity, conductivity porosity five brine saturated Berea sandstones as a function varying from 25 °C 140 °C. We find that velocity first increases...

ABSTRACT Improvements in the joint inversion of seismic and marine controlled source electromagnetic data sets will require better constrained models elastic‐electrical properties reservoir rocks. Various effective medium were compared to a novel laboratory set elastic velocity electrical resistivity (obtained on 67 sandstone samples saturated with 35 g/l brine at differential pressure 8 MPa) mixed results. Hence, we developed new three‐phase model for sandstones pore‐filling clay minerals...
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...
